Dot density themes are sometimes called dot distribution maps because they show where particular data characteristics occur. It uses dots or other symbols to represent the number of occurrences of a given data characteristic in a particular location. Starting at MAPublisher 8.4, the ability to create dot density maps is available through the provision of Dot Density Themes.

When creating a new MAP Theme simply choose "Dot Density" from the available theme types. The creation of a dot density theme is facilitated through the MAP Themes panel. The dot density theme is an Adobe Illustrator effect applied to an area layer.

In a previous blog, we discussed about how to georeference Adobe Illustrator document using MAPublisher. To recap, below are four of the required items to to make georeferencing possible:

1. The scale of the map in the Adobe Illustrator document (e.g. 1 : 25,000,000, etc.)
2. Details of the coordinate system the data is in (e.g. World Robinson projection, WGS84 geodetic system, WGS84 UTM Zone 32 N, etc.)
3. The XY coordinates of one tie-in point in the coordinate system of your map in the Adobe Illustrator document
4. The map's rotation angle.

We found that the most tricky information to collect is the coordinate system of the map. It can be very easy if it is clealy indicated in a map like this:

For many years, Esri has been promoting its geodatabase format. It is a great format that has many advantages over simpler formats and has seen many improvements and enhancements with each new version. We are pleased to announce that geodatabase feature classes can now be imported into Adobe Illustrator on both Windows and Mac using MAPublisher 8.4. Unlike the other geodatabase support feature within MAPublisher, this Basic Personal Geodatabase Reader does not require the installation of Esri ArcGIS products on the same computer because it uses a different import engine.

If you are using an existing Adobe Illustrator file that was created without the use of MAPublisher, then it does not contain any geographic parameters. The following step will enable you to georeference your Adobe Illustrator document and ultimately create an attribute-rich, accurate scale and world grid structure for your map. Please familliarize yourself with the main MAPublisher functions and in particular those in the MAP Views section of the MAPublisher User Guide (chapter 4) before proceeding.

Before beginning to georeference an Adobe Illustrator file, you must be in posession of the following information:

• The map scale in the Adobe Illustrator file (e.g. 1:25,000 etc.)
• Details of the coordinate system the data is in (e.g. World Robinson projection, WGS84 geodetic system, WGS84 UTM Zone 32 N, etc.)
• The XY coordinates of one tie-in point in the coordinate system on the map in the Adobe Illustrator document
• Finally, the MAP rotation angle value.

MAPublisher 8.4 has an exciting new feature: importing data from web services. It is another enhancement to provide you with more options to access data.

You can import vector data using the Web Feature Service (WFS). It accesses web servers that deliver vector content in GML format. Similarly, you can import raster data with the Web Map Service (WMS). It accesses web servers that deliver raster content in a variety of formats.
