GRASS Vector Attributes

Q: How to edit GRASS Attributes?

A: Some commands allow specification of attributes, shown as: attr=string|cat|double|coords|dim

The meanings of these terms:

• string: text label attribute
• cat: vector ID number
• double: double precision attribute
• coords: vertex coordinates
• dim: number of dimensions (2D, 3D etc)

Graphical editing can be done with the WxGUI Attribute Table Manager and the WxGUI Vector Digitizer

Command line editing can be done with v.db.update and related modules.
