Synopsisrastream [[-M splitmode] [splitmode options]] [-f file processing program -B secs] [raoptions] [— filter-expression] DescriptionRastream reads argus data from an argus-data source, and splits the resulting output into consecutive sections of records based on size, count time, or flow event, writing the output into a set of…
Raster data processing in GRASS GISRaster maps in generalThe geographic boundaries of the raster map are described by the north, south, east, and west fields. These values describe the lines which bound the map at its edges. These lines do NOT pass through the center of the grid cells at the edge of the map,…
3D Raster data (voxel) in GRASS GIS3D Raster (voxel) importThe module r3.in.ascii supports generic x,y,z import. Alternatively, voxels can be generated from 3D point vector data (v.to.rast3). Always the full map is imported. Volumes can also be created based on 2D elevation map(s) and value raster map(s) (r.to.rast3elev). Alternatively, a volume can be composed of…
