[GRASSLIST:9317] Re: GRASS and ArcSDE

[Dylan Beaudette]

David and others,

Frank W. on the GDAL list has recently announced support for SDE in OGR!!

It looks like real-world SDE support will be possible in GRASS via OGR. Not to 
sure how the raster support via GDAL is yet. Might be a good idea to lurk on 
the GDAL lists for a while...

Cheers,

Dylan
