If I may chime in, I repeat what Richard already explained actually, just for fun :-) The GRASS GIS data base is the root (of all good geospatial analyses :D). Inside it are put Locations. There can be only one reference system per Location. And, inside a Location, Mapsets help to organise stuff. Note, there is always a PERMANENT Mapset per Location and users may/should use it as a pool for imported data from which to draw the material that is to be processed. > Is the following command a "normal" way to make a location with a > projection from a georeferenced file: > > g.proj -c georef=/home/user/raster.tif location=example Absolutely. But, 1) be careful to define a "location=" otherwise the current location will be altered. 2) only from inside an existing GRASS Location! From outside, you may use something like the following grass70 -c /geo/geodata/SomePointOfInterest.kml /geo/grassdb/testing/Test_Location In this example, the georeferenced file "SomePointOfInterest.kml" will be used obtain information about the spatial reference system and a Location will be created. Actually, any georeferenced file recognised by GDAL/OGR should be a valid source Depending on how many of the directories given in the path pre-exist, a Mapset will be created (if GISDBASE and LOCATION pre-exist), a LOCATION will be created as the last part of the defined path (if only the GISDBASE pre- exists), etc. Please, check also the output of 'grass --help' if working in the command line (because the word "Scripts" is mentioned in the subject of this thread). > Is there a command to delete a location? No. One has/can simply delete it as any other directory. > I found g.mremove, but that seems to remove data, not locations. Yes, "g.remove" is for removing single elements inside a GRASS GIS data base (raster and vector maps, groups of raster maps and other). "g.mremove" (note "_m_remove" instead of simply "remove") is for removing multiple elements/maps in one go by defining a naming pattern using regular expressions.
