Example 11 with MatchResult

use of com.graphhopper.matching.MatchResult in project graphhopper by graphhopper.

the class MapMatchingTest method testSmallSeparatedSearchDistance.

/**
 * This test is to check what happens when two GPX entries are on one edge
 * which is longer than 'separatedSearchDistance' - which is always 66m. GPX
