DESCRIPTION

v.category attaches, deletes or reports vector categories to map geometry.

NOTES

Use v.to.db to upload the related categories a linked attribute table.

EXAMPLES

1) Report vector categories
v.category in=testmap option=report 
FIELD 1:
type       count        min        max
point          0          0          0
line        1379          1       1379
boundary       0          0          0
centroid       0          0          0
area           0          0          0
all         1379          1       1379

2) Delete all vector categories in field 1
v.category in=testmap out=outmap option=del

3) Add vector categories in field 1 with step=2
v.category in=outmap out=stepmap option=add step=2 

FIELD 1:
type       count        min        max
point          0          0          0
line        1379          1       2757
boundary       0          0          0
centroid       0          0          0
area           0          0          0
all         1379          1       2757

4) Add categories/centroids to a vector map without categories
v.category in=wkt out=wktnew option=add

Results can be tested using d.what.vect.
