Measure Height

Instructions for use

"Height" button, which is used to measure the height of the earth surface in the scene. At present, the height measurement function supports the height measurement of the model.

Operation steps

  1. The unit of height used for height measurement is meter.
  2. Click the Height button in the Measurement group on the Scene tab.
  3. Move Stop by Mouse to the Scene, and the mouse status changes to the selection status, so that the height can be measured on the surface of the earth in the scene.
  4. Click the left mouse button at the appropriate position on the earth's surface to determine the starting point of height measurement. At this time, move the mouse, and a temporary line with changing length connecting the current point of the mouse and the starting point will appear on the screen. This line is always perpendicular to the earth's surface, and the height value determined by the temporary line is also displayed.
  5. Click the left mouse button (or the right mouse button) when the height measurement calculation is finished, the value annotation of the current height will appear at the corresponding position of the height measurement calculation, and the value of the height measurement calculation will also be displayed in the Output Window.
  6. Click the " Clear" button in the " Measurement" group to clear the value annotation of height measurement in the current Scene.
  7. Repeat steps 1 through 6 if you need to continue with the height measurement.

Precautions

  1. Measure Height in the scene. It can only be measured on the Earth Surface. In other areas of the Scene outside the Earth, the height measurement is invalid.
  2. When there is no Terrain Data in the measured area, the height measurement takes the spherical surface of the smooth sphere (i.e., the surface of the smooth earth without considering the topographic relief of the earth's surface) as the starting point of the measurement; When the area to be measured has Terrain Data, the actual height point of Terrain Data is taken as the starting point of height measurement.
