Downstream Conflation Method in LP360

The Downstream Constraint method is used to create 3D polylines that are guaranteed to flow in the downhill direction. This method is useful for creating breaklines that hydrologically enforce streams in a downhill direction. The first step in the conflation method is to perform a drape of the geometry to the LIDAR surface. The drape…

New Contour Smoothing Algorithm

The new and improved contour smoothing algorithm removes noisy data which causes contour jaggedness by interpolating the Z elevation around contour levels, thereby smoothing the surface and creating much better contours. This display works for both the Map View and 3D view when the user has turned on this setting via the usual Smooth Contours…

Output by Line Macro Step

Output by line action can be used to write points into output files per line number. You would typically use this to produce final output files for delivering each line in a separate file. The output file format can be any of the supported file formats implemented in TerraScan or a user-defined point file format.…

Check Coverage

Check coverage command finds holes and areas of low point density in the project binary files. The area to be covered can be either defined by one or more selected polygons or by all block boundaries of the project. The application calculates the point density within sample areas and decides to which coverage level an…
