Measure

The mobile version of ArcGIS Earth provides basic 3D analysis tools that perform quick measurements on any 3D contents or objects in the scene. It calculates the analysis result in real time, making work in the field efficient and effortless.

Tap the Toolbox button Toolbox at the bottom of the screen and select the Measure tool Measure. Choose from the options below to start a measurement for the following:

  • Point Measure Point—Measure coordinates and elevation of a point on the ground.
  • Line of sight Line of sight—Create line of sight analysis given an observer point and target point.
  • Viewshed Viewshed—Create viewshed analysis given an observer point.
Additionally, you can change distance units of the measurements by tapping Unit Units at the top of the screen.

Measure a point

Measure a point with only a tap. Use the anchor point to help locate your point accurately and tap Add Add to measure. Tap Copy Copy to copy a measurement to your clipboard.

Measuring a point

Line of sight analysis

Perform line of sight analysis by specifying an observer point and a target point. Once finished, the visible segment is colored in green and the obstructed segment is colored in red.

  1. Use the anchor point to help locate your point accurately and tap Add Add to add an observer point.
  2. Tap Back Back to undo the observer point or tap Finish Finish to add a target point.

Viewshed analysis

Perform viewshed analysis by specifying an observer point. Once finished, the visible area is colored in green and the obstructed area is colored in red.

  1. Use the anchor point to help locate your point accurately and tap Add Add to add an observer point.
  2. Update viewshed parameters to adjust the viewshed analysis result on the fly.
    • Horizontal angle Horizontal angle—The horizontal angle of the field of view. Values range from 1 to 360 degrees.
    • Vertical angle Vertical angle—The vertical angle of the field of view. Values range from 1 to 360 degrees.
    • Heading Heading—The heading of the viewshed. Values range from 0 to 360 degrees.
    • Tilt Tilt—The tilt of the viewshed. Values range from -90 to 90 degrees.
    • Distance Distance—Specifies the maximum distance from the observer. Distance ranges from 100 meters to 5000 meters.
    • Height Height—The absolute elevation of the viewshed observer. Height ranges from 0 to 2000 meters.
