Modules
Import
- r.in.xyz - Create a raster map from an assemblage of many coordinates using univariate statistics.
(example)
- v.in.ascii - Import data from an ASCII file to GRASS vector format.
Limited to a few million data points unless topology and database creation is skipped
Analysis
- v.lidar.growing - Building contour determination and Region Growing algorithm for determining the building inside.
- v.lidar.correction - Correction of the v.lidar.growing output. It is the last of the three algorithms for LIDAR filtering.
Surface generation
- v.surf.rst - Spatial approximation and topographic analysis using regularized spline with tension.
- v.surf.idw - Surface interpolation from vector point data by Inverse Distance Squared Weighting.
- r.fillnulls - Fills no-data areas in raster maps using v.surf.rst splines interpolation.
Sample data
Widely used in GRASS tutorials
