Feature Description

The Isolines from Click feature extracts all isolines matching the elevation value at the mouse-click position.

  • The source dataset for extracting isolines must be a DEM or Grid dataset.

Application Example

Open the "Terrain" datasource in the "ExerciseData/RasterAnalysis" folder containing 5-meter resolution DEM data, which we'll use for demonstration.

Feature Entry

  • Spatial Analysis Tab -> Raster Analysis -> Surface Analysis -> Isolines from Click;

Steps

  1. Move the cursor over the map (cursor changes to crosshair), then click to select one or multiple points for isoline extraction as shown:
  2. After selection, right-click to open the "Isolines from Click" dialog displaying coordinates and raster values of selected points.
  3. Configure common parameters including target dataset, resampling coefficient, smoothing method, and smoothness in parameter settings. For parameter descriptions, see: Common Parameter Description.
  4. Click "OK" to complete extraction. Result example:
