## DIGITIZING MAPS

The commands listed below allow the user to enter paper (and other hardcopy geographic information) into GRASS databases, and to manipulate such data in GRASS. Their prefixes ("v.", "r.", and "s.") respectively denote whether commands operate on data in GRASS vector, raster or site_lists file format. The section, "Raster, Vector, and Sites Data File Formats," discusses these formats.

Although all of the commands listed below are used to develop new map data, "v.digit" is mainly used to develop new map data from non-digital sources. "v.digit" is a robust, highly interactive data development program used for vector digitizing, editing, labeling and converting vector data to raster format. The user can digitize data using either a digitizer hooked-up to his system, or GRASS's on-screen digitizing capability.

- v.digit - r.random - s.menu
- v.mkcontour - r.patch
- v.mkgrid
- v.mkquads
- v.support
- v.patch

For more information on a specific command, select a command and press ESC.
