Summary

The GT_SET_Z_PL command in GeoTools adjusts out-of-range elevation values in polylines by replacing them with the nearest valid non-zero elevation. This ensures a consistent elevation profile in BricsCAD, AutoCAD, ZWCAD and ARES Commander.

Set Out of Range Elevation Values to Nearest Valid Elevation Values: GT_SET_Z_PL – GeoTools Command

Key Features Include:

• Corrects Out-of-Range Elevation Values:
  • Scans polyline vertices and identifies those with elevations equal to or below a specified threshold.
  • Replaces these values with the nearest non-zero vertex elevation.
• User-Defined Elevation Threshold:
  • Allows users to specify a custom elevation value, treating any vertex at or below this value as out-of-range.
• Option to Delete Out-of-Range Vertices:
  • Provides the ability to remove invalid vertices instead of adjusting them.

Benefits:

• Ensures smooth and accurate elevation transitions in polyline data.
• Eliminates zero or out-of-range elevation values, improving terrain modeling and topographical accuracy.
• Helps in cleaning up surveyed data where incorrect elevations might exist.
• Improves 3D visualization and analysis by maintaining a consistent elevation profile.

This tool is particularly useful for surveying, civil engineering, and GIS applications, ensuring that polyline elevation data remains reliable and free of errors.
