Surface distance

Instructions for use

Used to calculate the grid surface distance, that is, the surface distance along a specified line segment or polyline segment on the 3D surface fitted by Raster Dataset. The distance measured by Surface Measure is on a curved surface, so it is larger than value on a flat surface.

Application provides two ways to calculate the surface distance: one is to measure the surface distance of the drawing object through the drawing object; the other is to directly select one or more objects in other Dataset to measure the surface distance (sum).

Operation steps

Surface Distance

  1. Open the Raster Dataset in Map for which you want to calculate the surface distance. Note: In Current Workspace, if there is no open Raster Data, this function cannot be used.
  2. In the Spatial Analysis tab-> Raster Analysis-> Surface Analysis-> Surface Distance item.

    3. Prompt in the Output Window: "Please use the mouse to draw a straight line or broken line on the map, and then right click to analyze", and the mouse status changes to the drawing status.

  3. Draw a broken line or straight line on the map and click the right mouse button to complete the operation.
  4. The Application displays the analyzed surface distance size in the Map and Output Window. The default distance is in meters. Hold down the Esc key to clear temporary line segments drawn in the Map.

Select Line Distance

  1. If both Raster Data and line data exist in the Map, select one or more line objects (hold down the Shift key to select multiple line objects).
  2. Measure the surface distance of the line object in the Spatial Analysis tab-> Raster Analysis-> Surface Analysis-> Select Line Distance subitem.
  3. The Application displays the analyzed surface distance size in the Map and Output Window.

Or do the following:

  1. From the Spatial Analysis tab-> Raster Analysis-> Surface Analysis-> Select Line Distance subitem, A prompt will pop up in the map, "Select one or more line objects for Surface Measure, and right-click to end the selection.".
  2. Select one or more line objects as prompted (hold down the Shift key to select multiple line objects), and right-click to end the selection.
  3. The Application displays the analyzed surface distance size in the Map and Output Window.

Note: When multiple line objects are selected, the measurement result is the sum of the surface distances of the multiple line objects. The default distance is in meters. Press and hold Esc to clear Map The selected state of the centerline object.
