Showing Selection Sets on a Map

When you select map features, Maptitude automatically shows features in each selection set in a distinctive style or color. You can further enhance the way a map looks by customizing the way selected features are displayed.

There are a number of ways that you can customize how selection sets are displayed on a map. You can:

Change the style that is used to display them
Change the color, font, or style of the labels
Hide the features in the selection set
Hide the layer so that only features in a selection set are visible
Autoscale a selection set to display only at certain scales
Zoom the map to show all of the features in a selection set
Zoom to individual features in a selection set

Maps showing customer selection sets highlighted in different ways

Selected features are highlighted in the map on the left. Selected features are highlighted, labeled, and other features are hidden in the map on the right.
