Overview
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 generates script-style output which is easily parsable.
Examples
North Carolina sample dataset example:
Query polygon at given position:
v.what zipcodes_wake coordinates=637502.25,221744.25Find closest hospital to given position within given distance (search radius):
v.what hospitals coordinates=542690.4,204802.7 distance=2000000Source code
