v.what v.what help v.what [-dag] map=name[,name,...] [east_north=east,north[,east,north,...]] [distance=float] [--verbose] [--quiet] Flags: -d Print topological information (debugging) -a Print attribute information -g Print the stats in shell script style --verbose Verbose module output --quiet Quiet module output Parameters: map=name[,name,...] Name of input vector map east_north=east,north[,east,north,...] Coordinates for query If not given reads from standard input distance=float Query threshold distance Default: 0


v.what Outputs the category number value(s) associated with user- specified location(s) in user-specified vector map layer(s). This module was derived from the d.what.vect module by removing all interactive code and modification of the output for easy parsing. Using the -g flag permits to generate script style output which is easily parsable. This module always reports standard acres, even when the location uses US Survey feet as the map unit.
Spearfish example: v.what fields east_north=599121.75,4922981.125
