--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

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. 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.

EXAMPLE¶

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