## METHODS OF INPUTTING DATA TO GRASS

Data must be digitally stored in a GRASS database in order to be used by GRASS programs. Data can be entered into a GRASS database in one of the following ways:

(1) Hardcopy data (like paper maps) may be either digitized or
scanned into GRASS's vector file format;

(2) Data already available in another digital format (like ARC-INFO
data) may be converted into GRASS's digital data file format,
and stored in a GRASS data base;

(3) GRASS analysis programs can be used to create new GRASS data
from data already stored in GRASS digital data file format.

For further information on data entry into a GRASS database, refer to the "Digitizing and Map Development" section, located at the Help System Main Menu.
