That would be simply great! With SpatiaLite support evolving in GRASS, QGIS and (perhaps) gvSIG, there would finally be a sane way for direct exchange of vector data between open source GIS without crippling it by going through abominations like Shapefiles. Ben - Original Message - From

You're on the right track. If you have obtained a an ESRI GRID representing a DEM in an e00 format, then with GDAL and/or GRASS you can convert from ESRI GRID (e00) to USGS DEM format, with the workflow Hamish outlined previously. ESRI data is in binary raster/vector formats when ESRI software is
