Army steering committee established.||Distribution to several hundred sites. Pilot tested by Soil Conservation Service. Adopted by National Parks Service.|
|1988||GRASS 3.0||Image analysis reworked into GRASS; runs on all GRASS machines. Raster files can contain from 1-4 bytes per cell. DLG dropped in favor of an internal vector format. Completely new digitizing package for user. Full assortment of command-line driven programs. Approximately 170 different programs.||Distribution to about 1000 sites.|

Table 2: GRASS History
"Now users that have paid the significant costs of joining the Internet have easy access to GRASS3.1. GRASS as a public domain product has no distribution restrictions. Programmers who use the UNIX utility ftp can log in using the login name anonymous and any password to uxc.cso.uiuc.edu (18.104.22.168). GRASS files can be found in the directory pub/grass. Your local guru will be able to make sense of the files found therein.
Happy GRASSing, Gurus"
