Cartographer Chronicles: Thorfinn Tait

Cartographer Chronicles Thorfinn Tait

A teacher by day and a cartographer by night, Thorfinn Tait (a native of Scotland) has been teaching high school in Japan for almost 20 years while making maps of fantasy lands in his spare time.

Mapping is a hobby for Tait, and his deep love of atlases, along with fantasy role-playing games (known as RPGs), helped drive him towards creating his own maps of fantasy worlds. He started in 2005, making maps in Adobe Illustrator. His goal was to create an atlas of a fantasy world, that included the same variety of maps that you’d find in any traditional world atlas — topographical, political, thematic — along with all the tables of data typically found in an atlas. He chose to map the world of Mystara, a popular Dungeons & Dragons (D&D) campaign setting from the 80s and 90s.

Tait set out to compile all of the original maps of Mystara (more than 250 of them) into a cohesive whole. “One of my biggest struggles was trying to work out what projection Mystara’s maps used. But there was a fundamental disconnect for me in that Illustrator alone did not have the functions I needed,” says Tait. “For example, to change the projection of a map, I tried to use it in tandem with other GIS software, but it was very troublesome having to constantly import and export elements between programs.”

While working on the Atlas of Mystara project, an original Mystara author made a return to the industry, and Tait volunteered to remake his maps in Illustrator. The year after, that same author commissioned Tait to map a new RPG world, the World of Calidar. Determined to avoid the same problems he’d encountered with Mystara, he began establishing dimensions of the new world and creating custom projections based on them. But, working between Adobe Illustrator, Adobe Photoshop and GIS software was still very complicated.

World of Calidar

I managed to complete the first assignment with just those tools, but as soon as I got my first commission, I invested it right back into my maps by purchasing MAPublisher and Geographic Imager.” With MAPublisher, a plug-in for Adobe Illustrator and Geographic Imager, a plug-in for Adobe Photoshop, Tait could work natively in both Illustrator and Photoshop.

“My favourite aspect of MAPublisher is without a doubt the custom coordinate system. It allows me to create resources for fantasy worlds just like they already exist for the real world, and then repurpose them across all of my maps,” says Tait. He also uses MAP Attributes and adds data to the world’s geography. “For example, it’s easy for me to track things like road and river lengths, land areas, dimensions of coastlines and political borders, and so on — MAPublisher calculates all of these things for me automatically.”

MAPublisher has allowed Tait to take his previous work and convert it to the newly established custom coordinate systems, without losing any of the GIS attributes he’d created over previous years. Tait also uses Geographic Imager to create Digital Elevation Models (DEMs) for the World of Calidar. DEMs can help bring maps to life, adding an intricate level of detail and depth.

Tait’s tagline for his freelance business is “Mapping fantastic worlds with real-world accuracy”. “I couldn’t do this without MAPublisher and Geographic Imager,” he says. “The software allows me to create and work with data for a fantasy world just like other people map the real world, the only difference is that I am creating all the data myself!”

“MAPublisher has truly expanded my horizons as a cartographer and has also changed the course of my projects. Without it, my current work would simply not be practical — in fact, probably not possible at all.”

Tait is currently working on georeferencing existing Mystara maps and tagging elements with their original sources. Check out more of his mapping projects on his website!

MAP Chart Themes: Doing More with Your Data

We all love a good choropleth map, but sometimes we need our map to display more than just different shades of colour to communicate more detailed information. MAP Chart Themes are the perfect way to distribute that extra bit of information that you want your readers to know. You can display the data in a bar chart format, or pie chart format. There’s even the option to have the charts change scale according to the data.

Say you have a map showing the population density of Toronto, like this map below.

MAP Theme Density Map

But, while this shows just the density of the population, you want to go more in-depth. For example, you want to look at all the ethnic origins of the residents of each neighbourhood. This is the perfect opportunity to use MAP Chart Themes.

To create a MAP Chart Theme, open the MAP Themes panel (Window > MAPublisher > MAP Themes) and click the + button to create a new Theme. Then choose Chart as the Theme type.

Create MAP Chart Theme
Once you’ve created your theme, now you can get to making your charts! You can use either bar charts or pie charts, choose whichever will show your data best. To show the variety of ethnic origins for the neighbourhoods in Toronto, I chose a pie chart.

MAP Chart Themes Settings

Select a layer, then click the Add Attribute button (the green plus icon) to add your attributes. Select the attribute you want to include in the chart, and style it as you see fit. The preview at the bottom will update as you make changes to the components of your chart. There are options to change the size of the chart, and even turn it into a donut chart!

MAP Chart Themes Donut Chart

If you want to include a title for your charts you can, but because my map contains so many charts in a relatively small area, I chose not too. Labels for the sections of the charts can also be added as well. Edit the test if necessary, and even label your pie charts with percentages if that helps to better communicate your data.

MAP Chart Themes Labels

My favourite feature is the Scaling option (button is on the right). This allows you to automatically scale the size of your charts based on attributes. You can set the scale by defining the value that represents 100%, then select an attribute, click Load and watch the magic happen. This feature is super handy especially if you’re creating a map with tight boundaries or not a lot of extra space because you can easily adjust the size of all charts at the same time.

MAP Chart Themes Scaling

Back to my example map, I set the scaling and applied the MAP Chart Theme. Since there are 140 neighbourhoods in Toronto, I chose an inset of the larger map to show how the scaling appears. You’ll see neighbourhoods with a higher population have a larger pie chart, while neighbourhoods with a lower population have a smaller chart.

MAP Chart Themes

The scaling feature works for bar charts as well. I created another map with data showing the total number of inter-province visits for each Canadian province in 2016 vs 2017. In this case, I chose not to change the scale of the charts (by total number of visits per province) so it’s easier to see the comparison.

MAP Chart Themes Bar Charts

If you’ve made it this far in the post, and have eagle-eyes you’ll notice that there are no charts for the Territories or the Maritime provinces. Since I only wanted to visualize the data for some of the provinces, I used the Ignore option in the MAP Chart Themes box. It’s handy when you want to exclude certain data, for any reason.

MAP Chart Themes Settings

There you have it! An easy way to visualize that extra data that your readers want to know, and you want to share without making your map overly complicated. Looking for more details on Chart Themes? Find it in the MAPublisher Documentation available on our website. 

Using Automation in MAPublisher

We are always looking for shortcuts to make work easier for our MAPublisher users. One way to simplify your workflow is by automating some of the routine tasks that are required to make maps using MAPublisher in Adobe Illustrator. Not everyone is familiar with software automation, or even knows that it’s available in MAPublisher but if you are curious to learn more, then keep reading!

Automation tools in MAPublisher help to make simple or repetitive tasks easier and faster. Automation can be run independently or in conjunction with the FME Auto MAPublisher Plug-in which allows more advanced automation. The Automation tool can be accessed from the automation button (lightning bolt) on the MAPublisher toolbar, or by clicking in the menu Object > MAPublisher > Automation.

MAPublisher Toolbar Automation

There are several automation options available in MAPublisher. You can use automation to create MAP Grids, apply labels, apply applicable MAP Stylesheets, and even export to geospatial PDFs. An important point to note, to use automation on a MAPublisher document, the document must be active in Illustrator.

Automating Map Views

If you’re planning to use automation, you’ll have to enable the specific options you would like to automate. For example, to import data to a matching MAP View, simply enable the MAP Views option, and select from the dropdown list the tasks that you want MAPublisher to complete. Make sure that the coordinate system of data being imported matches a coordinate system of the existing MAP View, then select one of the four actions for your data.

MAPublisher Automation MAP Views

Automating MAP Themes

If you’re a fan of MAP Stylesheets (we all know they make our lives easier) then you can have MAPublisher apply them using automation. Enable the option and MAPublisher will apply any  MAP Themes that meet the criteria to the imported data. Don’t forget to set the ‘Auto-assign’ in the specific MAP Stylesheets themselves as well since you can’t link layers that haven’t been imported yet. If the ‘Auto-assign’ properties aren’t set correctly, your data will import but the stylesheet will not be applied.

MAPublisher Automation MAP Themes
Automating Grids & Graticules

For Grids & Graticules, you can set the extents for the grid bounds with either the MAP View or a layer that you’re going to import. If you’ve already created configuration files for your grid, then select either ‘All configuration files in this folder’ or ‘Only these configuration files’ if there is a need to use only certain configuration files.

Automating Labeling

When you enable labeling, choose either MAPublisher labeling or LabelPro. You’ll also have to choose a specific setting in the MAPublisher Preferences (Edit > MAPublisher Preferences > Import MAP Data). Uncheck ‘Append feature type as the suffix on imported layer names’ to be sure that your labels import properly.

To use the regular Label Features option, set the details such as the source layer, target layer, attribute, and the style. You can add as many layers as you need with the Add Layers button on the left, and remove as necessary. If you’re using LabelPro, simply load the .lps file.

MAPublisher Automation Labeling

Automating Export to Geospatial PDF

Last but not least, if need your document to be exported to a geospatial PDF as the last step of the automation process, enable the option and specify the location you’d like it saved in. Once you’ve selected all of your automation settings, import your data to watch your automation work!

Enabling automation in MAPublisher can speed up your map making process, and make your workflow easier. Save yourself extra steps when working with stylesheets and grids you’ve already created, and let automation do the work for you. Simple MAPublisher magic!

More MAPublisher Features We Love

Last year we wrote a blog post about some of our team’s favourite MAPublisher features. Not surprisingly for software that has been around for over 20 years, everyone had a different favourite and we had to be selective for the blog post. This year, with new team members coming on board and new MAPublisher releases it’s a good time for a new list of favourites. Check out some of these features that you might not know about, and find out how they can make your workflow easier!

Create Elevation Plot

Jeff C. – Quality Assurance

Prior to MAPublisher 10.3, “Create Elevation Plot” was a feature of Path Utilities I seldom used because, to be honest, it had a few limitations. MAPublisher 10.3 introduced a completely new way of creating elevation profiles, and the difference is astounding. The available customization options are endless – not only can you select whether your axes will use metric or imperial units, but you can also set the Line Colour, Line Width, Fill Colour, Background Colour, Axis Intervals, Axis Labels, Graph Size and much more. Another aspect of this updated tool that I love is the ability to save and re-use ‘styles’. These styles remember specific elements of an elevation profile (e.g. appearance, units, size, etc.) and can be applied to other profiles made in the future, saving the user a lot of time.

Elevation Plot Created in MAPublisher

Text Utilities

Keith  S.- Quality Assurance

In my opinion, the Text Utilities tool is one that is underutilized in MAPublisher. The tool allows you to perform actions on text within a document, including Curve Text to Latitude, Draw Shape Around Text, Merge Text, Create Line From Text on a Path, and many more. The actions can be performed on selected text only, text on specific layers, or all text in the document. The tool even allows the user to preview most actions before committing the changes.

If you have ever seen text along a path with a red plus symbol at the end of it after performing a transformation or manual adjustment it is an indication that the text path is not long enough to contain all of the text. No problem for my favourite action in the Text Utilities tool—Extend Overflowing Text. This utility solves the issue by extending the text path to a length which will accommodate the full length of the text.

Join Lines

Oliver N. – Customer Support

One of my favourite tools to use in MAPublisher is the Join Lines tool. If you are working with a road or rail network and sections of the same track or street connect to each other but are broken into different line features, you can easily join them into single features with a common attribute like Street Name or Track Number. You can target a line layer and then in the Destination options, choose either to perform the join on the original target layer or specify a name for a new line layer that will contain the joined lines. You can also use a proximity value to determine how close the lines must be in order to be joined. I find that this tool allows subsequent styling to be done easily and saves a lot of time in arranging the data to your needs. It also reduces the size of your file by compiling data into fewer features.

Copy MAP Objects From

Keith S. – Quality Assurance

This feature allows users to copy MAP objects (including MAP Views, MAP Layers, MAP Themes, MAP Selections, and MAP Locations) from one open document to another. MAP Views can be copied by themselves or with their associated MAP Layers. The best part is, that any artwork which is copied to the destination document will retain its styling provided that the custom colour swatches used in copied artwork are set as “Global” in the Adobe Swatch Options dialog. It works like this: With the destination document open, launch the Copy MAP Object From tool. Select the object(s) you want to copy to the destination document by checking the checkbox beside each object, then click “OK” to perform the copy. Copy MAP Objects From is one of my favourite features because it saves so much time when styling maps!

MAP Themes Scaling Charts

Bob P. – Business Development Associate

My favourite way of making infographic maps is using our MAP Chart themes. Within Chart Themes, you can add a bar or pie chart to any point layer, based on any set of attributes from the point layer. For an added level of information, each of the charts can be scaled based on the value from another attribute. This helps when you want to show the proportion of values, but also give an indication of the total population size for each point too. The best part is MAPublisher allows you to pick between Area and Radial scaling for pie charts. If the population of one point is twice the size of the smallest point, it can either have twice the area, or twice the radius length. This is my favourite tool in MAPublisher, because it shows that our team thinks of everything to make sure cartographers can make the exact map they want, right down to the smallest details.

Mapping Love: Celebrating Valentine’s Day by Creating Infographics

Happy Valentine’s Day! What better way to celebrate than with new maps (and creating infographics) about love? This year we’ve hunted for romantic data for Canada and the United States and visualized it all for you using MAPublisher 10.3 and Adobe Illustrator.

The first map shows all the most romantic locations (at least as their names suggest) in Canada. This information was provided by Stats Canada. Using the MAPublisher Point Plotter, it was easy to plot all of the locations!

The best part about using the Point Plotter is you can choose any symbol available in your symbol library to mark the points. I chose the symbol that I wanted (a Valentine’s map marker–how adorable!) and then plotted each location simply by using the town’s name and province.

Canadian Point Plotter - MAPublisher

After adding some text and symbols in keeping with the theme, the map was ready to go! You can check out the PDF below, or, you can download the georeferenced version from the Avenza Map Store, for use in the Avenza Maps app

Romantic Places Map made with MAPublisher

 

Moving on to my infographic – which is a popular and engaging way to illustrate statistics and small amounts of data that might otherwise be overlooked. I found data from the United States covering a variety of Valentine’s Day topics. The plan is for my infographic to include two maps and two additional charts. The first map illustrates the average wedding cost by state, and the second map shows popular proposal locations.

For the average wedding cost per state map, I used a MAP Theme to colour all the states appropriately (and quickly!). The benefit of using a MAP Theme is that you can apply a theme to multiple layers at once. Since Hawaii and Alaska were projected separately from the mainland of the United States, they exist in different layers on the artboard. Using a MAP Theme made it easy to include them in the colour scheme of the map.

MAP Themes - MAPublisher

On the second map, I want to map the most popular proposal locations in the country. I used the MAP Point Plotter tool again, but, this time, I used the latitude and longitude to plot the points because some of the locations could not be plotted by name alone. It’s very beneficial to be able to swap between the two options!

USA Point Plotter - MAPublisher

My maps are complete, and after adding two graphs (made using the graphing tools in Illustrator) containing even more fun Valentine’s day data, and some love-ly symbols, the entire infographic was finished. You can check out the completed infographic below!

Accurate Georeferencing with Geographic Imager

Georeferencing is the process of adding spatial information to a physical map or raster image. Geographic Imager includes a georeferencing tool and also includes two methods of validating georeferencing so that your imagery is not only beautiful but also spatially aware (that’s two of the four keys to great maps!).

Use the Georeference feature in Geographic Imager to reference an image by establishing ground control points, choosing a transformation method, and specifying a coordinate system. It can also be used to rectify—transform or warp—an image to match the image coordinate system specified. The Validate and Show Image Extents Online tools are used to test georeferencing accuracy.

Geographic Imager - validating georeferencing accuracy

The Validate tool provides a visual comparison of the accuracy of your image to the real world. Use the Validate tool by clicking a point on the image to see the corresponding location on a web map.

The image below shows the Validate tool in action. Select the tool and click on a road intersection to open the web map with the same intersection identified. If the two don’t match, consider georeferencing again. It is good practice to test several known points on the image to ensure overall accuracy. Choose features that will be easy to identify on the web map such as road intersections, coastlines, buildings, and landmarks.

 

The Show Image Extents Online tool displays a rectangle representing the spatial extent of the image on the web map. Use this tool to verify that the full area covered by the image is accurate. Note that the rectangle shown on the web map will include the non-map areas of the image including the borders, legend, etc.

 

Geographic Imager - Show Image Extents

 

It’s that simple! Using Geographic Imager, you can manipulate imagery in Adobe Photoshop while now ensuring spatial integrity!

Making The Orthographic Projection in MAPublisher Work for You

The Orthographic projection is a commonly used projection by cartographers because it closely resembles the world as we know it exists – a three-dimensional sphere (sorry “Flat Earthers”). However, when MAPublisher displays the world in the Orthographic projection, it will still draw any points, lines or polygons that fall beyond the perspective’s horizon. This can create a “hollow Earth” or see-through effect that would cause confusion to the map reader.

Orthographic Projection in MAPublisher - Avenza Systems

Further confusion may arise depending on the order of the artwork within the layers, as some features that should be on the far side of the Earth may appear on top of features on the near side of the Earth. In order to prevent these inaccuracies, we need to remove the data beyond the horizon before transforming the data to the Orthographic projection. The following workflow is one example of how to overcome this limitation. It can be easily adapted for any orthographic projection with a custom latitude of origin and/or central meridian.

Step 1: Plot Your Centre Point

Import your world dataset and ensure the MAP View is in WGS84 (or you can use the world.mif file from the MAPublisher Tutorial Data folder).

Next, decide where you want the final orthographic map to be focused on. In this example, our focal point is 70°N, 100°E. Create a point layer, and plot your centre point using the MAP Point Plotter tool.

Plotting the focal point - MAPublisher

Step 2: Project to Azimuthal Equidistant Projection

Reproject the map to Azimuthal Equidistant (with a sphere-based datum). To do so, go to the MAP Views panel > Edit Map View. Enable Perform Coordinate System Transformation and click the No Coordinate System Specified hyperlink.

Under the Projected > World category, find Lambert Azimuthal Equidistant (Sphere), meter and click the Copy Object button to begin editing a copy of the existing Lambert Azimuthal Equidistant (Sphere), meter coordinate system.

Making a copy of Lambert Azimuthal Equidistant (Sphere) - MAPublisher


Side Note – Why start with the Azimuthal Equidistant projection?

The straight-line distance between the central point on the map to any other point is the same as the straight-line distance between the two points along the earth’s surface.

Furthermore, you must use the ‘Sphere’ version of the Lambert Azimuthal Equidistant projection, because the radius is equal in all directions. The other version of the projection uses an ellipsoid datum which would require more complex formulas to solve the buffer distance in Step 3.


Next On the Definition tab, set the Central Meridian to 100, and the Latitude of Origin to 70. You may rename the custom projection on the Identification tab if you wish to reuse it later. Click OK and apply the projection.

Editing the parameters of the Lambert Azimuthal Equidistant copy - MAPublisher

Step 3: Create the Horizon Line

Create the horizon line from your custom centre point. Next, add a buffer of 10,002.5 km (see note below) around your focal point.

Creating the horizon line - MAPublisher


Curious about where the buffer value comes from?

Given that we know:
Earth’s radius using Authalic Sphere is 6,371,007m
The formula for the circumference of a sphere = 2πr
The distance from the focal point to the horizon in the Azimuthal Equidistant projection = 1/4 of Earth’s circumference = C × 1/4

 

Relationship between Earth’s circumference and the horizon line - MAPublisher

We can first determine the circumference by:
= 2πr
= 2 × π × 6,371,007
= 40,010,000 m

Now that we know Earth’s circumference, we can determine the distance to the horizon by:
= C × 1/4
= 40,010,000 × 1/4
= 10,002,500 m or 10,002.5 km


Step 4: Convert Your Custom Horizon Line

Convert the resulting circle with four Bezier curve points to polylines using MAPublisher’s path utilities tool Convert Beziers to polylines. This is your horizon line.

Converting bezier paths to polylines - MAPublisher

Step 5: Back to WGS84 and Editing the Horizon line

Import another copy of your world file. If necessary, transform it to WGS84 and drag your horizon line into this MAP View. You can also hide or remove the Lambert Azimuthal Equidistant MAP View.

Transforming horizon line - MAPublisher

Use Illustrator’s Direct Selection Tool to select and delete the horizontal portion of the horizon polygon.

Next, use Illustrator’s Scissors Tool to cut the polyline at the artboard edge

Move the section of the curve remaining outside the artboard inside and to the opposite edge.

Adjusting the horizon line - MAPublisher

Resize the artboard to match the extents of the WGS84 MAP View. Use Illustrator’s Pen Tool rejoin the two lines into one. Continue using the Pen Tool to close the polygon by following along the edge of the artboard (result should look similar to the image below). Export the polygon area in case you need to add additional data at a later date.

Closing the horizon polygon - MAPublisher

Step 6: Crop Beyond the Horizon

Use the Crop to Shape tool to remove the features outside of the polygon.

Preparing to crop the world to the horizon polygon - MAPublisher

Crop result to the horizon polygon - MAPublisher

Step 7: Reproject the Remaining Data

After cropping, go to the MAP View and Perform Coordinate System Transformation. Choose the Orthographic, meter projection, click Copy Object to begin editing the coordinate system and put in the custom central meridian and latitude of origin you chose back at the beginning of the workflow. Once the custom Orthographic coordinate system is created, complete the MAP View transformation.

Making a custom copy of the Orthographic coordinate system - MAPublisher

Step 8: Remove Lingering Polar Points

If there are any lingering polar points, you can delete them from the horizon line manually using the Direct Selection Tool.

Cropped dataset reprojected to the custom Orthographic coordinate system - MAPublisher

You’ve successfully projected your data into a custom orthographic projection without any overlapping features from the other side of the Earth.

 

Enhanced Orthographic projection - MAPublisher

The best part is, all of the map features retain their attributes, so you are free to continue applying MAP Themes, generating labels, and any of the other design tools at your disposal to make your map project a work of art.

Bridging the Gap Between ArcGIS and Adobe Illustrator with MAPublisher

Maybe you already know that MAPublisher has the ability to let you import shared data layers from your ArcGIS Online organizational account and to connect to publicly available map servers from various online sources. Once GIS data is imported, you can use Adobe Illustrator’s powerful design tools to style and edit your map into a thing of beauty. The ability to import from ArcGIS has been available for a while, however, it’s still a question that people ask our Support Team frequently. So, here’s a reprise of a blog post, from a while ago, that illustrates how to import layers directly from ArcGIS Online or an ArcGIS web service into Adobe Illustrator, using MAPublisher.

Esri’s ArcGIS Online is a collaborative web geographic information system (GIS) that allows you to store and share GIS data using Esri’s secure cloud. Use MAPublisher to import Feature, Map Image, and Tile layers into Illustrator without losing any georeferencing, features, or attributes. MAPublisher does not currently support the use of Map Image or Tile services that use Dynamic layers.

Importing from ArcGIS Online

To load a layer, use the MAPublisher Import tool as you would with any data type and select ArcGIS Online from the Format drop-down menu. Click the login link to enter your ArcGIS Online credentials to access your organization’s web portal.

MAPublisher Import Dialog Box

MAPublisher - Online User Portal Dialog

Feature Layers contain vector data that will import as artwork into Adobe Illustrator. You can reduce the time it takes to import by filtering the data first, isolating only the layers that you need.

Map Image Layers and Tile Layers are raster data layers that can be added by selecting the geographic extents.

Import from Map Image Layer

Importing from a Web Service

In addition to using your organization’s data, you can get publicly available data by connecting to an ArcGIS Web Service. To connect to a web service, use MAPublisher Import and select ArcGIS Web Service from the Format drop-down menu. Click to select the dataset and enter the URL for the service. This is a great option when searching for data from open data portals created by government agencies.

Import from Web Service

Connect to ArcGIS dialog

MAPublisher bridges the gap that exists between Esri’s Online services and the full-featured design environment of Adobe Illustrator. You can leverage Illustrator’s tools on GIS data shared within your organization, or from a publicly available source to make better, more beautiful maps.

Creating Elevation Profiles in MAPublisher

In the latest release of MAPublisher, version 10.3, we added some great new features including the ability to create elevation profiles. The new Elevation Profile tool allows you to create an elevation plot using elevation information from anchors (vertices) of a line as long as there is a single path in a MAP View, with a coordinate system. You can also use the Elevation Profile tool to easily make changes to an existing MAPublisher elevation profile.

Example 1 – Trail Elevation

For the first example – take a satellite image of Tunnel Mountain in Banff, Alberta. I gave the image a coordinate system and georeferenced it in Geographic Imager then imported into MAPublisher as a GeoTIFF. Using the pen tool, I replicated the trail system for Tunnel Mountain while adding anchor points (vertices) throughout the line feature. These anchor points are the source of the elevation information in the resulting profile. Alternatively, you can import the trail data from another source and add your own additional anchor points using the Add Anchor tool.  The screenshot below shows the anchor points indicating each line vertex.

MAPublisher - Trail showing Anchor Points 

These anchor points correspond with the points on the elevation profile below. Once finished, select the line feature to access the Elevation Profiles tool.

MAPublisher - Edit Elevation Profile

Editing Profile Options

The Edit Elevation Profile window lets you customize your profile manually with advanced customization tools or using a simplified built-in MAPublisher style. The advanced tools allow you to alter the size of the profile, intervals, axes, colour scheme, units of measurement and plenty more to ensure that you can make your profile unique and convey the desired information. For example, select “Edit series appearance” as shown in the screenshot, to choose whether you want your series to be a smooth line, or to display your individual anchor points. Additionally, select “Edit axis appearance” to customize the colour of your grid or change the appearance of your labels. Customize the look of your profile with the built-in stylized templates.

MAPublisher Elevation Chart Styles

I chose the “Temperate” style, for the example profile below, to stay true to the land cover as you can see above.

Elevation Profile - Tunnel Mountain

Now, in addition to making great trail maps in MAPublisher, the Elevation Profile tool allows you to create a valuable extra feature which could be exceptionally beneficial for hikers!

Try experimenting with the additional built-in styles that reflect the appearance of other land types available as well, such as Sierra, Arid, Boreal, and Fluvial which is featured in our next example.

Example 2 – Fluvial Depth Profile

The nautical map below takes aerial imagery from the National Agriculture Imagery Program (NAIP). Depth data is extracted from the line feature that extends from the marina into the Strait of Georgia in Washington, USA. Port Roberts map

Port Roberts Elevation Profile - MAPublisherThe fluvial depth profile shows the increase in depth the deeper into the Strait.

If you import track data into MAPublisher and add your own anchor points, you can see the elevation or depth reached on your excursion by creating an elevation profile from your track.

Depending on where you drop your anchor points, you can convey everything from coastal change by creating elevation profiles for a temporal series of aerial photos of the same area, to elevation or depth change of a hiking trail on a mountain in one of Canada’s most popular destinations or a sailing trip off the west coast.

Summing Up

With the release of MAPublisher 10.3, you can now make beautiful maps that also communicate elevation information with ease. The new Elevation Profiles tool will help make your maps that much better!

MAPublisher 10.3 Released

We’re excited to announce the release of MAPublisher 10.3 for Adobe Illustrator. We’ve listened to your feedback and worked closely with our users to build features to improve map design and productivity. Stay tuned for more blog posts and other resources that go deeper into some of the new features. For now, here’s an overview:

MAPublisher 10.3

This update contains new features and performance improvements as well as fixes for reported issues. Some highlights are summarized below, for the full release notes see below.

Compatible with Adobe Illustrator CC 2019. We’re committed to providing the best GIS and cartography tools for building great quality maps in Adobe Illustrator. Improvements to our user interface to support high-resolution monitors, and this release is fully compatible with the latest Adobe Illustrator CC 2019 on both Windows (32-bit and 64-bit) and Mac.

Create Elevation Profile charts. An often-requested feature from our users, elevation data for points along a selected path can now be collected and displayed as an elevation profile in a highly customizable chart. The data is downloaded in real-time from a server (internet connection is required), which can then be customized to your liking using the available settings. Frequently used settings can even be saved for future use.

View data distribution when batch generating rules in MAP Themes and MAP LabelPro. When selecting a data classification in MAP Themes or MAP LabelPro, you now have the ability to see how it affects the data distribution in an interactive histogram and chart. Histograms are a great way to visualize continuous data in intervals and useful for large sets of data points.

Improved attribute capabilities in ‘Join’ tools. We have added many attribute management improvements to MAPublisher Join tools (Join Areas, Join Points, and Join Lines). You can now better manage how attributes are handled during a Join process, including the ability to calculate new attributes. We also added additional operations to help you better sort and calculate statistics from attributes.
