AGIS TO GRASS CONVERSION

[Marty Burks]

John Sparco,
	I too was frustrated at the AGISTOGRASS data conversion. We here
at SOIL CONSERVATION SERVICE wrote a complex program that converted 
attributed poly data that got rid of duplicate area edges. You can note
however, that you must seperate data types into seperate classes. ie:
poly,lines and points. One also must note that AGIS is very forgiving in
building topology. Your data must be clean in order not to end up with
slivers in GRASS. The process is done by selecting polys, writing out to a new file, using ie to make a .bna with 2 names, and using "v.in.atlas" in grass.

	You can obtain a cp of "v.in.atlas" & "v.out.atlas" from CERL.
It should be somewhere in "sourcd.contrib.SCS.

	If I can be of any assistance you can reply to sender or
call (817) 334-5212
