Contours From Raster Tool

Contours from Raster

This tool converts a raster surface model, such as a DEM, into a vector contour coverage. Users can specify the contour interval and optionally the base contour value. The tool also offers parameters for smoothing the contour lines and generalizing the contour paths.

Input parameters

• Input surface raster file – Select the file that will be modified.
• Contour interval – Defines the vertical spacing between contour lines in the output vector contour coverage
• Base contour height – Sets the starting elevation for the first contour line in the output vector contour coverage
• Smoothing filter size (in num. points), 3, 5, 7, 9, 11 – Specifies the size of the mean filter applied to the x-y positions of contour vertices, with larger values producing smoother contour lines.
• Tolerance factor, in degrees (0-45); determines generalization level – Sets the threshold for angular deflection required to retain vertices in the contour line.

Output parameters

• Output contour coverage – Enter the name for the new generated coverage.
