Our friends in the map library at Brock University in St. Catherines, Ontario have put together a very nice how-to on creating super overlays for Google Earth using Geographic Imager and Adobe Photoshop.
These instructions describe the process of georeferencing a high-resolution image, creating a geotiff file, using Google Earth Pro to make a super overlay and how to provide access to others. The full process is outlined here https://www.brocku.ca/maplibrary/Instruction/Creating_a_super_overlay.pdf

HTML5 is the current major revision of HTML (Hypertext Markup Language), the core markup language of the Internet. One of its major development goals was to reduce the need for proprietary, plug-ins such as Adobe Flash and to provide new graphics drawing abilities to the canvas element of HTML5. Scripting (e.g. JavaScript) is used to draw graphics, animations, and display other types of content. The potential of applications in online mapping with HTML5 technology varies widely including uses in fields such as cartography, GIS, demographics, and statistics.
Introduction to HTML5 Map Web Author
As maps become more detailed and data sources becoming richer, the way we present multiple data layers and map projections in dynamic map zoom levels and extents, traditional web mapping techniques start to become too limited. While many current web maps are rendered and served through a server, this could limit the amount of data provided and be slow to transfer as more and more tiles are served. MAP Web Author uses a technique to make maps from Adobe Illustrator compatible with browsers that support HTML5, specifically the canvas element. The maps exported using MAP Web Author are not server-side rendered, instead, they are rendered on-the-fly and content dynamically changes when the map is panned or the map zoom level is changed. This ultimately produces a more flexible, interactive and dynamic map. An HTML5 map also has more efficient storage and requires less space than other web map technologies. Stored vector map data (points, lines, and areas) is more efficient than raster tiles and can be displayed at any scale and even styled using CSS. Since HTML5 technology replaces browser plug-ins like Flash or Java, web maps generated by MAPublisher are accessible on Android, iOS, and Windows mobile devices (smartphones and tablets).
Files created from export
After exporting your map using MAP Web Author to HTML5 format, several files will be created. A ready to use index.html file and an index_data folder. The index.html file contains pre-formatted code necessary to view your map. In most instances, you can simply open the file in a browser to view the web map.
The index_data folder contains all of the necessary map layer data, JavaScript files, and CSS files to display your map.
How to embed an HTML5 web map into your site
The viewer will be embedded inside of a div element in your page (the “container div”). The map view will fill the container div.
For mobile specific sites we recommend setting the width and height of the container div to 100%, then using max-width and max-height to limit the width to the size of the map. The style should fit in the head, like this:
The following script tags must be included in the head tag as well. These scripts contain JavaScript functions that allow the map to function, like so:
Keep note that the prefixUrl points to the directory where your map data is stored. It should be a relative path to avoid cross-site access errors. The id is used below in the body of your page.
Within the body tag, place the div element where appropriate. Specifying the div element id initiates the JavaScript to display the HTML5 web map. If a browser that is not compatible is used, then the message is displayed.
<div id="map_container">
<div style="display:none">
<!--
The message below will appear instead of the map if
a user connects with a browser that does not support
enough HTML5 for the map viewer to function. You may
wish to customize the message for your site.
-->
A web browser that supports HTML5 is required in order
to view this content. If you are seeing this message
then your current web browser does not.
Please upgrade.
</div>
With MAPublisher 8.6 or higher, you can apply styles to GIS data upon import using the MAP Stylesheet Auto Assign feature.
You will need to prepare MAP Stylesheet theme(s) and set the Auto Assign settings within every stylesheet. In this example, there is only one stylesheet.
In the “Edit Stylesheet Theme” window, there is a link to click next to the “Auto-assign” right below the layer option. Once you create all the rules for stylization using attribute values, click the link to open the Auto Assign Layers dialog window.
MAPublisher will check the layer name of all the layers being imported if the Auto-Assign Layers settings are made. In this example below, one layer named “USA 2000.shp” will be imported. There may be other layers called “USA 2001.shp”, “USA 2002″…. and so on. There is a pattern in the layer name among the layers to be imported. We will specify here “Start with” for the Type, and “USA” for the Layer Name Match option.
For the Type option, there are five: Equals, Start with, Ends with, Contains, and Wildcard. All my layers start with “USA” in the example above.
Let’s import one layer called “USA 2000.shp” (you can import mutiple layers at once, of course).
If the Adobe Illustrator document has this Auto-assign setting ready, MAPublisher will detect it and it will give you an option whether or not you would like to apply the styles to the layer(s) being imported. We’ll click the first option “Apply MAP Themes to imported layers now”.
As a result as shown on the very top screencapture image, every polygon in the layer “USA 2000.shp” is stylized with the rules available in the MAP Stylesheet theme upon import.
Summary:
In September 2010, Avenza Systems, Inc. released the first version of PDF Maps for the Apple App Store where both free and for-pay versions of maps in the Geospatial PDF format could be downloaded for use with the iOS operating system. Currently, over 100,000 maps are now available for download. Are users likely to download maps normally found in a print version to their iPhone or iPad? Editor in Chief Joe Francica sat down with Avenza president, Ted Florence for more details on the “the iTunes of maps” business model – selling maps the way iTunes sells music.
Directions Magazine (DM): The transition from publishing printed paper maps to the digital world is a difficult one for many publishers who have been in the map business for many years. Why has the transition been so slow when we’ve had online mapping and the platform, the Internet, for many years?
Ted Florence (TF): Most publishers who have heretofore catered to the printed map audience have neither the means, the know-how nor financial capability to jump into the digital world, and hence a real catalyst was required. That is the essence of where Avenza’s PDF Maps app and digital map store solution come in. While the migration from analog product to digital product has unfolded over the last few years and the better part of the last decade for book and music publishers, map publishers (save for those with means of their own) have only been able to enviously sit back and watch as their printed map businesses have started to struggle. And recognizing that catalysts like Apple, with iTunes and iBooks, and Amazon, with Kindle, have made themselves available to music and book publishers, one could argue that were it not for those catalysts, music and books may not have made the migration either. Furthermore, the cost of transitioning can be very expensive and even prohibitive for many publishers, not to mention that undertaking such major initiatives as creating their own app or mapping device could likely distract most publishers from their main business of producing and delivering maps. So again, despite the fact that the paper or analog to digital transition has proven to be a viable model in the book and music industries and the demand for digital maps has increased with the advent of powerful smartphones and tablets, the map industry has lacked a similar manner of both transitioning and ultimately transacting in maps and has thus been faced with the simple dilemma of how to make that transition, at least until now.
DM: You’ve come up with a new model to support the transition by taking the archive of printed maps and exposing a new delivery method for the publishers. Can you explain the business model in some detail?
TF: The business model for the Avenza PDF Maps app and map store solution is very simple. Think of it basically as iTunes or Kindle but for maps.
The PDF Maps app and solution is an all-encompassing solution for the use, distribution and sale of digital versions of paper maps to mobile devices. Similar to iTunes for music, the Avenza PDF Maps solution includes both an app for users to discover, purchase and use maps directly from and to their devices, as well as a back-end store to facilitate the transaction and delivery of the maps. The app on the smartphone or tablet device contains all the functionality for using maps both on- and offline, including locating oneself, measuring, plotting points, importing and exporting points, and much more, all of which goes well beyond traditional paper map usage. Users can carry around dozens of maps on their device just like they are now accustomed to carrying around a library of music or books. On the other side of the equation, and again like iTunes and Kindle, the app has a built-in map store which connects users to a vast and growing library (currently over 100,000 titles) of maps from around the world and representing multiple genres and publishers. Users may browse and search through this catalog and quickly and easily find, purchase and download the map or maps of their choice, may of which are offered free of charge. Maps are then immediately and automatically delivered wirelessly to the device.
Any geo-referenced map may be uploaded to the system and made available for purchase in a fully electronic manner similar to the way in which music, videos, books and apps are currently sold and delivered.
Additionally, users may add their own maps directly into the Avenza PDF Maps app via a variety of methods. This is particularly useful for private and public-sector organizations that have a need to use their own private maps out in the field while doing work on tablets or smartphones such as iPads and iPhones. So the insertion of maps into the app is not exclusively dependent upon a purchase and download from the in-app map store.
DM: If your new model is essentially “the iTunes of maps” why wouldn’t one of the larger publishers like National Geographic or Rand McNally try to use their brand to do this themselves?
TF: This is certainly an option for all publishers, and some will do that, however, as many publishers are finding, the development and ongoing maintenance of such a dedicated app is very time-consuming and costly. That is why one of the business models in the Avenza PDF Maps solution is a customized or OEM offering of the Avenza PDF Maps app whereby publishers can avail themselves of the functionality and transaction model of the Avenza PDF Maps solution without the time and overhead required to do it all themselves. Moreover, though, as we look at the trail blazed in the music and book industries by iTunes and Kindle, we find that all the various publishers have gravitated to a one-size-fits-all solution in which all music publishers provide their offerings through a single place, iTunes, and all book publishers do so though a single place like Kindle or iBooks. What we do not see are dedicated apps for each publisher. We do not see individual music players and digital stores for Sony, Arista, Def Jam or Geffen nor do we see individual readers and digital stores for Penguin, Random House or Harlequin. Furthermore, on the user side, the fragmentation of the offerings is really not ideal or desirable as users do not want to have dozens of music and book apps on their devices in order to find, maintain and use their content. Simply put, why reinvent the wheel? We have seen how successful the digital music and book transition has become under this model, so why should we try to be any different in transitioning the map industry?
DM: Give us a better understanding of the app delivery method. How do you envision the store to function and what “departments” will you have in the store to make it easy to find content?
TF: Just like with iTunes, iBooks and Kindle, users can access a digital map store directly from within the Avenza PDF Maps app on their device. From within the map store they can browse various map categories or genres such as tourist, transit, recreation, nautical, aeronautical and special purpose, or enter any search term that might apply to a map they are looking for such as a geographic place or term or a particular map use case such as cycling or camping. Additionally, the map store interface allows for finding maps near to one’s current location, browsing recent additions to the map store and browsing the most popular maps at the time. Searches by publisher or brand may also be performed should users have a particular brand or publisher loyalty.
Once they have located a particular map of interest they can simply touch the listing to reveal more information about a map such as publisher, date of publication, file size and full description and even see a full preview of the map in order to feel comfortable that they have found a map they want to purchase. Then, as is done with music in iTunes, they simply touch the “buy” button and complete the transaction.
On iOS devices (iPads, iPhones and iPod Touches) the payment comes seamlessly via the user’s iTunes account and then the map is delivered to the device. Essentially the system functions with the same elegance and simplicity that users are accustomed to when purchasing music and books.
DM: What does the store look like in three years? How do you envision the model developing over time?
TF: Currently there are over 100,000 maps in the map store from over 200 government and commercial publishers and more are being added all the time, every day. We expect this to continue to grow and eventually become the de facto place to purchase maps, much like iTunes has become the place to get music. It would not surprise me at all if we had over one million maps and many millions of users within two to three years. Just ask yourself this: If you need a map of a particular place for a particular use on your device, do you know where to get it? Well, we intend to answer that question for everybody, with the answer being the Avenza PDF Maps store.
There is no other model like this catering to the map industry and as more and more users discover it and more and more publishers realize it to be a viable and costless solution for them to enter the digital map business we see it indeed becoming the iTunes of maps.
We are currently working on an Android version of the solution followed by Windows Mobile and possibly Blackberry, as well as a Web-based interface and store for users who might prefer to do their map shopping on a computer screen rather than on the mobile devices themselves. This is something that music and book purchasers are already able to do, so why not maps as well? As these platforms are unveiled, continued growth is anticipated as new audiences get added. There is no doubt that there is a demand for this type of user and publisher solution so essentially the sky is the limit.
If you haven’t noticed yet, we released an enhanced version of the Grid and Graticules tool (MAPublisher 8.7 and higher). With the new Grid and Graticules tool, you will find that you can export grid settings and save them. Most importantly, these grid settings files can be shared and imported to another document.
Once a grid is created, save the settings to a *.cfg file. Two configuration files are created per grid: grid settings and label settings.
Grid settings configuration files store information for all related grid options (e.g. ticks, intervals, offsets, borders). Label settings configuration files store information for all related label options (e.g. axis labels, fonts, styles), even for multiple grids. Label settings are saved with _labelData suffixed to the file name.
Share the files and load the *.cfg file in the Grid and Graticules dialog box.
Some of the major functions of the new Grid and Graticules tool are adding tick marks along border lines, placing cross hair symbol instead of lines for grid/graticule lines, styling lines and text more flexibly, and having more label options available. You can share the settings by exporting one and importing to another document as well. You can make a set of grid lines looking like this below.

Updated: August 6, 2015 – New URL syntax for QR codes
Delivering mobile maps just became even easier for Avenza Maps vendors. This is a brief overview of how vendors can easily create QR codes (Quick Response Codes) to help promote, sell, and deliver their maps electronically.
A QR code is a two-dimensional barcode that can be easily scanned using any modern mobile device. When scanned, the mobile device automatically launches a web browser to direct the user to a website or other action. In our case, the map product page (free or purchase) in the Avenza Map Store.
These QR codes can be strategically placed on printed maps, signage, websites, advertising and anywhere else your maps are promoted.
This is an example of such a QR code:
When scanned on a device that has Avenza Maps installed, this code will automatically launch the Avenza Map Store listing for Avenza’s Amsterdam map. From there, one can browse details about the map and immediately purchase it. In this case, the QR code contains a special URL to which only the Avenza Maps app will respond.
Create a QR Code to launch an Avenza Map Store product listing
Previously, two types of URL syntaxes—one each for Android and iOS—were used to create QR codes for map downloads. This is no longer the case. With the most recent update to the Avenza Map Store, only one URL syntax will be needed to create QR codes compatible for both Android and iOS.
The new URL syntax now shares the same link from the Avenza Maps site and will look like this: http://avenzamaps.com/maps/{mapsku} (e.g. http://avenzamaps.com/maps/62190). Adding a title to the URL is optional: http://avenzamaps.com/maps/{mapsku}/{title}. If a title is added, any spaces in the title should be replaced with dashes. For example, a map listing that has a SKU number of 61290 and a title of Amsterdam Netherlands will yield the URL http://avenzamaps.com/maps/62190/amsterdam-netherlands. To retrieve the URL of one of your maps, go to your Avenza Map Store vendor page, view one of your map listings and copy its URL.
Once you’ve retrieved the URL of one of your maps, simply go to one of the QR code generators recommended below:
Some sites provide an option to download the QR code in different formats. We recommend saving the QR code as a high resolution image or SVG.
Examples of QR codes to deliver maps from the Avenza Map Store
As described earlier, QR codes can be used with Avenza Maps to drive a map purchase, but they can also be used to effect the download of any map within the Avenza Map Store.
QR codes with the Avenza Map Store can be a very effective way to deliver a free map, such as those found in transit shelters, tourist offices, car rental counters, parks, and trail heads. In such cases, for example, a QR code can be placed on a transit map in a bus shelter or on a signpost at a trail head, and anyone equipped with the Avenza Maps app who may be looking at that map can scan the code and immediately get the map delivered to their device. Here is an example of such a sign Avenza used recently at an event in San Diego, CA.
Imagine seeing such a sign on a hotel concierge desk, city tourist office or in an airport and how easy it would be to quickly obtain a map for that city.
Here is an example of how the City of Stavanger, Norway has employed a QR code on their city maps placed in popular and high foot-traffic areas.
Photo and map courtesy of Stavanger Guide Maps Norway.
Notice the QR code in the lower right corner directing viewers to the Avenza Maps app.
Lake Mead National Recreation Area has also implemented QR codes by adding them to posters placed in Visitor Centres and other strategic areas to allow visitors to get their hands on the park map before hitting the trails.
What else can you do with QR codes and maps?
QR codes can be strategically placed on printed maps, signage, websites, advertising and anywhere else your maps are promoted.
They can be placed on a paper map product to offer a digital copy of the printed map to someone who buys the paper one.
They can be used in magazine and newspaper articles to offer a map for sale for a destination mentioned in the article. If a map is used in an article a QR code can be used to offer that map.
QR codes can be placed on websites to enable the purchase of a map that is shown and offered for sale on that website.
They can be used on maps and map signage, such as those in Stavanger or on a hiking trail head map sign, to offer the same map that someone may be looking at on the sign.
They can be used on signs on hotel concierge desks, travel agencies, airports and train stations and any other place where travels congregate.
The ideas one can come up with are endless and we encourage everyone reading this to explore and exploit the use of Avenza Maps QR codes in their sales and distribution tactics.
The new MAPublisher 8.7 Georeferencer is a fast, easy, and accurate way to update your current unreferenced map collection or data to prepare it for PDF Maps or other digital formats.
The first step is to open your unreferenced document in Adobe Illustrator. If the document is a vector PDF it is often advantageous to rasterize the document and save it as a TIFF to avoid any conflicts with text.
Once the map is open, we can use the Map Locations tool to place reference points or Page Locations on our unreferenced map. It is recommended that known points, or points that are unlikely to move such as the intersections of road ways, are used as reference because these locations will be easily recognizable (as seen in the following steps). Tip: You will also want to zoom in as close as possible to the point to ensure the best possible accuracy.
After we have given a name to our page location we will continue to place page locations until there is four or more spread as evenly across the map as possible. Having greater than four reference locations could help to improve the overall georeferencing accuracy.
The next step is to find the real world counterparts, or World Locations, for each of our Page Locations using the Georeferencer tool. World locations can be sourced from an online map service, an open referenced document or entered manually. In this example we will use the built in Google Maps service to find our World Locations.
The Google Maps option opens the Add World Locations dialog box. Choose a Page Location from the drop-down list and use the map to find the corresponding world location. Use the Google search bar and zoom buttons to zoom as close as possible to the corresponding world location. Place the cross hairs over the location, click, and confirm the world location with the page location.
If the point is accurate, we will continue to add world locations for each page location. If not, the world location position can be changed by clicking and dragging it to a more accurate location. Right-click the pin to delete it.
If you’re unsure about the position of the original page location, you can drag the Add World Locations dialog box to the side and use the Zoom to artboard tool to help locate it.
After we have placed all of the World Locations with the corresponding Page Locations, we may now either specify a coordinate system (if one is already known) or click on Georeference and Save.
After clicking Georeference and Save, a list of possible projections will be presented. Select the projection which most accurately represents your map. With each projection we see an associated error. This error is based on the combined accuracy of our Page and Map locations.
As in this example, the first ranked projection is not always the best fit for our map, so it is best to use your best judgment when selecting a projection.
Click OK and add your map to a Map View and save. Your map is now referenced!
We can check the accuracy of our georeferencing by zooming in closely to our Page (green) and Map (blue) locations. The further the distance between the two points, the less accurate a given georeferenced map is.
You can also see a video of the Georeferencer in action on our YouTube Channel.
As we have all seen over the last decade, the distribution and consumption of music, videos and books has moved to a digital model and so, the question then becomes, why not maps? Similarly to the aforementioned media types, maps are also very conducive to both the distribution and use in a digital and mobile way. As we see organizations like Borders, Blockbuster and Kodak succumb to this digital revolution, we map-makers must adapt or suffer a similar fate.
Many of you may be struggling with the issue of selling your maps digitally, tackling the question of the “mobilization” of your content and wondering how to attack the new markets.
But what if there were a generic iTunes/iBooks/Kindle type environment where a map publisher, like many of you reading this, could offer their maps for sale just like musicians and book publishers currently do with their songs and books? There is and it’s called the Avenza Map Store, accessible through the PDF Maps app.
Right now, the Avenza Map Store has more than 100,000 maps from publishers all over the world and we are looking for more as we strive to become the “iTunes of maps”. Map sales in January have already more than doubled December in terms of both units and dollars and December was higher than previous months already.
So here is the gist of the system and the thinking behind it.
What is PDF Maps?
The award winning PDF Maps app is an all-encompassing solution for the use, distribution, and sale of digital versions of paper maps to mobile devices. It includes both an app for users to use, discover and purchase maps directly using their devices as well as an in-app store to facilitate the transaction and delivery of the maps.
Think of it like iTunes, iBooks or Kindle, but for maps.
The app loads georeferenced maps and has functionality for locating (via GPS), measuring, plotting points, importing and exporting points and much more, this goes well beyond traditional paper map usage.
Why PDF Maps? What are the advantages?
The PDF Maps app and the connected map store responds to the demand of both map users and map producers for a 21st century digital map consumption and delivery solution. In an era where a vast amount of content is shifting from analog to digital delivery and use, the map industry demands a similar solution for its users and producers.
For the user it solves four major problems:
How can I use a map I really like on my mobile device instead of the often less-desirable ones Google and other streaming services offer?
Google and other streaming services fail to perform when there is no Internet connection such as when hiking or traveling in remote unconnected areas.
Services that rely on a bandwidth connection are very undesirable when outside your home network area due to the high cost of data roaming charges.
Google and other streaming services, as well as many existing mobile apps, do not always offer a useful map for a particular purpose such as hiking, boating, and visiting national parks which leaves much desire for a “better” map.
For publishers it responds to the following specific needs:
With paper map sales declining, how can I get my content into the digital age for the mobile device market?
Devices like Garmins, TomToms and in-car navigation systems are usually closed to outside map content and thus map producers cannot easily, if at all, make their maps available to users of these systems.
In an effort to get into the digital marketplace it has to be easy, efficient, and inexpensive to repurpose existing content and map libraries. In most cases existing map libraries can be easily ported to the PDF Maps system and existing production processes do not need to be drastically modified, if at all, in order to produce new content for PDF Maps and the Avenza Map Store
With digital map use there is no printing, production quantity guesswork, inventory to manage, distribution and returns to account for.
Updates to the maps are controlled by the vendor and can be instantly made available to the marketplace, while at the same time, older redundant content can be instantly removed and discontinued.
Immediate, easy and effortless entry into the digital map marketplace.
