Generating elevation annotations

Summary

Using point cloud and contour lines to generate elevation points for topographic mapping.Notes Elevation Points File.

Usage

Click Terrain > Generating elevation annotation.

Settings

• Input Tiff File: Input DEM file format in LiData.
• Input Contour File (.shp): Input Contour file format in shp，The file needs to contain one or more contours.
• Radius (m)(default value is "15"): A Note Elevation Point is generated within a region with a defined radius.

• Output path: The path of the generated contour lines file(s) to save.

• Point Cloud: The input file is a single point cloud data file.

• Contour File: Input contour file in SHP format, which should contain one or multiple contour lines.

• Sampling Method: Includes Circle, grid, and diamond sampling methods.

• Sampling Distance: The distance between adjacent sampled annotation points.
• Conflicting Notes: Method for handling conflicting annotation points. Keep: retains originally sampled elevation annotation points; Modify: adjusts conflicting annotation point elevations based on adjacent contour lines; Delete: removes conflicting annotation points.
• Output Path: The output path for elevation annotation points (only valid when contour lines are in SHP format).
