Topic: geometry

i.image.mosaic	Mosaics several images and extends colormap.
r.patch	Creates a composite raster map layer by using known category values from one (or more) map layer(s) to fill in areas of "no data" in another map layer.
r.thin	Thins non-null cells that denote linear features in a raster map layer.
v.delaunay	Creates a Delaunay triangulation from an input vector map containing points or centroids.
v.drape	Converts 2D vector features to 3D by sampling of elevation raster map.
v.edit	Edits a vector map, allows adding, deleting and modifying selected vector features.
v.extrude	Extrudes flat vector features to 3D vector features with defined height.
v.hull	Produces a 2D/3D convex hull for a given vector map.
v.in.region	Creates a vector polygon from the current region extent.
v.mkgrid	Creates a vector map of a user-defined grid.
v.overlay	Overlays two vector maps offering clip, intersection, difference, symmetrical difference, union operators.
v.parallel	Creates parallel line to input vector lines.
v.patch	Creates a new vector map by combining other vector maps.
v.perturb	Random location perturbations of vector points.
v.report	Reports geometry statistics for vector maps.
v.segment	Creates points/segments from input vector lines and positions.
v.select	Selects features from vector map (A) by features from other vector map (B).
v.split	Splits vector lines to shorter segments.
v.to.3d	Performs transformation of 2D vector features to 3D.
v.to.lines	Converts vector polygons or points to lines.
v.to.points	Creates points along input lines in new vector map with 2 layers.
v.type	Changes type of vector features.
v.voronoi	Creates a Voronoi diagram constrained to the extents of the current region from an input vector map containing points or centroids.
