LIS Profiles
LIS Profiles provides tools for extracting, analysing and visualising cross-sections and transects from point clouds, raster datasets and vector data. Profiles can combine information from multiple datasets and be interactively inspected, measured and exported. Typical applications include examining terrain cross-sections, comparing point cloud elevations against a DTM, analysing changes between surfaces acquired at different times, measuring building heights, and checking vertical clearances between high-voltage power lines and the terrain.
Tool: Profile Plotter
