NAMEv.what - Queries a vector map at given locations.KEYWORDSvector, querying, positionSYNOPSISv.whatv.what --help v.what [-dagjm] map=name[,name,...] [layer=string[,string,...]] [type=string[,string,...]] coordinates=east,north [distance=float] [--help] [--verbose] [--quiet] [--ui] Flags:
Parameters:
DESCRIPTIONv.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 generates script-style output which is easily parsable.EXAMPLENorth Carolina sample dataset example:Query polygon at given position:
