Filtering the attributes map

The 'Extensions→atFitlerAM→Filter attributes map' menu option allows you to merge land types in your attributes map based on pre-defined filters. Clicking on that menu option opens the 'select filter' window, shown below.

Once you select your filter and click OK, L3DT will apply the filter and re-draw the attributes map.

The filters listed in this window may be edited using the filter manager.
