Types allow you to classify items. Every item in ExpertGPS (waypoints, routes, tracks, shapes, and notes) has a type. A hiker might create waypoints with these types: Trailhead, Intersection, Summit, Camp. A farmer might use shapes to mark his fields, and give them these types: Corn, Soybeans, Fallow.
An item's type determines how it is displayed on the map. If you look at a professionally made map of your area, you'll see that all of the lakes are displayed using the same color and font. All of the airports are displayed with the same symbol and font. Color, font, and symbol provide strong visual clues that make the map easier to read and understand.
ExpertGPS allows you to create and manage your own personal list of types that meet your mapping needs. The Edit
dialogs for each item in ExpertGPS (Edit Waypoint dialog, Edit Route dialog, etc)
contain the Type Controls, which you will use to manage your personal type lists.
