Chapter 9. Completing the ForestTrails Application

In this chapter, we will complete our implementation of the ForestTrails application that we started building in the preceding chapter. So far, our application displays the basemap and lets the user zoom and pan across the map. We've also implemented the track editing mode, though the user can't enter or edit track data yet.

In this chapter, we will add the following features to the ForestTrails application:

  • Map tools that let the user add, edit, and delete tracks

  • A toolbar action that lets the user view and edit the attributes for a track

  • The Set Start Point and Set End Point actions

  • Calculating and displaying the shortest available path between the two selected points using a memory-based map layer
