Define Region

When displaying a map, you might want to obtain information on selected portions of the map. The Draw | Region commands allow you to specify a selection region by drawing a ellipse, rectangle, or polygon. Alternatively, you can select boundary objects by their primary IDs or in the Plot Window to create a selection region or buffer zone.


If you want to define more than one selection region at the same time, you can use the Draw | Region | Add command. The selection region you define remains displayed on the screen until you define another selection region, or you choose the Draw | Region | Clear command.


Once you have defined the region or regions, you can use the Analysis | Data | Records in Regions command to display information for the contained boundary objects.


Create a region with one of the following Draw | Region commands:


Selects boundary objects within a user-defined circle


Selects boundary objects within a user defined rectangle


Selects boundary objects within a user defined polygon


Selects boundary objects within an automatically generated buffer zone
