Instructions for use
Specified Isoregions can extract a certain number of isosurfaces of specific values as required by the user. You can directly enter a specific value, or automatically generate a series of elevation values according to the set range and interval. You can also import a specific value stored in a *.txt file.
- The Source Dataset for Extract Isosurface must be a DEM or Gird Dataset.
Application Example
Open the Terrain "Datasource under the Exercise Data/Raster Analysis folder, and there is DGM data with a resolution of 5 meters, which we will use as an example.
Function entrance
- On the Spatial Analysis tab-> Raster Analysis-> Surface Analysis-> Extract Specific Polygons;
- Toolbox-> Raster Analysis Tools-> Surface Analysis-> Extract Isolines/Areas-> Extract Specific Polygons. (iDesktopX)
Main parameters
- Value: you can directly enter a specific value, or click the "Batch Add" "button to pop up the" Batch Add "" dialog box, where you can set parameters such as the starting value, ending value, step length and segment number of the isosurface, and then click the "OK" button to return to the "Specified Isoregions" "dialog box.
- Set parameters such as resampling factor, smoothing method, and Smoothness. See: Public Parameter Description .
- Click OK to complete the isosurface extraction operation.
During Specified Isoregions, you can also import and export isosurface information in.txt format, and delete one or all current isosurface information. Use the buttons in the toolbar to import, export, delete, and delete all from left to right.
Starting value: The initial starting value of the iso-surface is generated.
End value: The maximum value of the generated iso-surface.
Step: The level distance between two adjacent isosurfaces from the start value. The default unit is the same as the Source Dataset unit.
Number of segments: The total number of isofaces in the Target Dataset. After the step length is determined, Application will automatically calculate the equivalent value.
