Seeing the 255 attribute limit brought to mind the original ARC/Info (which I used on a Prime and on early PCs in the late 1980s and early 1990s). Info was limited to 1024 characters per row which was often a serious constraint for environmental analyses.

That effectively answers my question. I miss the old .e00 format (used with GRASS-4.x) which had (still has) two advantages over shape files: 1) it includs topography and 2) it's in plain text easily read by humans and computers.

I know this because last year I started a thread on using geodatabase files and was shown how to do it by those who know. I'm sure it's in the mail list archives. For some reason I'm not finding it in my local grass mail file. Rich ___ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user

I have had success reading data from geodatabases in R and QGIS, but only vector layers. If they have embedded rasters you will need Arc to get them out. -- Sent from: http://osgeo-org.1560.x6.nabble.com/Grass-Users-f3884509.html ___ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
Re: [GRASS-user] geodatabase or shapefile?
Rich, Have you figured out a way to read a geodatabase in GRASS? I think it can be done in R, and with rgrass7 you can probably bring the data into GRASS. Shapefiles are pretty straight forward in GRASS.

[GRASS-user] geodatabase or shapefile?
US National Wetland Inventory datasets are available in two flavors: geodatabase and shapefile. What are the benefits of one format over the other for use with grass, other than the former being much smaller (compressed) than the latter?
