MAPublisher MAP Themes: Assign Symbology and Styles upon GIS Data Import

With MAPublisher 8.6 or higher, you can apply styles to GIS data upon import using the MAP Stylesheet Auto Assign feature.

MAP Theme Auto Assign  upon import

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.

MAP Theme Panel

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.

MAP Theme Auto Assign: Layer name pattern option

Let’s import one layer called “USA 2000.shp” (you can import mutiple layers at once, of course).

Importing a shapefile for an example

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.

MAPublisher Dot Density Maps

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.

Item 2: Coordinate system of the map

As dot density maps are most useful for showing where particular data occur, they may only be generated for MAP Area type layers. Most often, symbols are used to represent data occurring within a bounding polygon such as a census tract, zip code or county polygons.

Item 2: Coordinate system of the map

Dot density effects are created on a per layer basis, based on various user defined settings. Data ranges can be determined from selected attribute columns and then a dot value can be assigned a corresponding symbol at which point MAPublisher will map the appropriate results. Users may apply default symbols or load custom ones based on Illustrator symbol sets

In this example, population tallies per county have been loaded, assigned a dot value of 10,000 with a designated symbol of a 2pt black dot.
