Examples with PMap com.graphhopper.util.PMap used on opensource projects

Example 16 with PMap

use of com.graphhopper.util.PMap in project graphhopper by graphhopper.

the class MapMatchingTest method testDistantPoints.

/**
 * This test is to check behavior over large separated routes: it should
 * work if the user sets the maxVisitedNodes large enough. Input path:
 * https://graphhopper.com/maps/?point=51.23%2C12.18&point=51.45%2C12.59&layer=Lyrk
 * <p>
 * Update: Seems to me that this test only tests a long route, not one with
 * distant input points. createRandomGPXEntries currently creates very close input points.
 * The length of the route doesn't seem to matter.
