The Map Access sample demonstrates how to access map data from the Maps module. The sample mimics a car driving along a GPS path, visualizing the map around the car. The map geometry is stored as polylines of WGS84 coordinate points. It shows how to query the map data around a current position, how to transform the geometry into a local Cartesian coordinate space, and how to render that data from various views.
The command line for the Map Access sample, sample_mapaccess, is:
./sample_mapaccess
The sample plays automatically, running through a fixed route of GPS points.
While the application is running the following actions are possible:
The output window is split into 3 parts:
