v.digit consists of two parts: an initialization procedure, and a multiple menu-driven environment.
Area, line, and point features may be digitized in both "stream" and "point" modes. Both a mouse and a digitizer may be used to perform windowing functions. Labeling and editing are done from within v.digit, rather than through a separate set of programs.
v.digit has capabilities that allow users to display raster maps in background (Customize menu, Backdrop), to overlay already existing vector map layers onto the feature being digitized (Customize menu, Overlay), and set a multitude of parameters to furtherly customize a digitizing session.
v.digit may be used with or without a digitizer. Many options are available if no digitizer is used, i.e. digitizer support by mouse.
All options available within v.digit are contained within ten menus. Movement from menu to menu is done by chosing the movement options specified at the bottom of each menu.
Digitizer support
GRASS is using device independent code written originally by John Dabritz formerly of the Forest Service, which uses ascii description files to define how to communicate with the digitizer. The result is that we should be able to support just about any digitizer out there now with a minimum of work. Refer to the "digitizer definition manual" for information on the format of these files.
