DESCRIPTION

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.

This module always reports standard acres, even when the location uses US Survey feet as the map unit.

EXAMPLE

Spearfish example:
v.what fields east_north=599121.75,4922981.125
