The custom symbology includes variable scale display, user-specified line, point, and polygon symbology, and label text. Different classes of features can be created from a single layer by defining a SQL query. The MDRE saves these changes as a Map Template File, which is then used to display data in the TGDE viewer. The template file and the data need not be on the same computer as the Viewer. It is included with the Enterprise Pack, or available separately.
Programmers can define their own events in response to clicks on the map.
Active data layers and recordsets can be fully defined to suit the application's requirements. Map views can be pre-defined for ease of use. In addition to TBMMap, the full power of Visual Basic is available to the programmer.
