Class LocationDistanceMeasurement

  • public final class LocationDistanceMeasurement
extends Analysis
    LocationDistanceMeasurement measures the distance between a start and an end location (each using Point geometry). Three distance components are calculated:
    • Direct distance - the direct distance between the start and end location
    • Horizontal distance - the horizontal component of the direct distance
    • Vertical distance - the vertical component of the direct distance
    The analysis must be added to an AnalysisOverlay within a SceneView before distances will be returned. The units of the distance components are specified using setUnitSystem(UnitSystem).
