> GRASS has been developed for over a decade as completely unrestricted
|
|
public domain source code and executables. Though there was initial
|
|
resistance to the existence of such robust software in the public
|
|
domain, many competitors learned to take advantage of GRASS. It has
|
|
reputedly been the intellectual stimulus for several enhancements to
|
|
other GISs. Several companies conducted business by installing and
|
|
customizing public domain GRASS for customers, and by providing other
|
|
value-added services such as data base development.

> As USA/CERL no longer supports the public version of GRASS, users are
|
|
free to use what currently exists. They're also currently completely
|
|
on their own. At least where the public domain version is concerned.

sold its GRASSLAND for Sun, Linux and Windows NT. LAS is trying to

encourage the continuation of a robust public domain Linux, partly as

a source of new ideas and code for their own developments.
