Distance measurement analysis

Measure distances between two points in 3D.

screenshot

Use case

The distance measurement analysis allows you to add to your app the same interactive measuring experience found in ArcGIS Pro, City Engine, and the ArcGIS API for JavaScript. You can set the unit system of measurement (metric or imperial).

How to use the sample

Click 'Change units' to choose a unit system for the measurement. Click any location to update the measurement.

How it works

  1. Create an AnalysisOverlay object and add it to the analysis overlay collection of the SceneView object.
  2. Specify the start location and end location to create a LocationDistanceMeasurement object. Initially, the start and end locations can be the same point.
  3. Add the location distance measurement analysis to the analysis overlay.
  4. The MeasurementChanged event will be raised if the distances change. You can get the new values for the DirectDistance, HorizontalDistance, and VerticalDistance from the event arguments.

Relevant API

  • AnalysisOverlay
  • LocationDistanceMeasurement
  • LocationDistanceMeasurement.MeasurementChanged

Additional information

The LocationDistanceMeasurement analysis only performs planar distance calculations. This may not be appropriate for large distances where the Earth's curvature must be considered.
