[GRASS-user] can't ingest an E00 file using r.in.gdal, or anything else?

I’m not sure why this is not working, and I’m having a little trouble getting a satisfactory answer on the web.

I’m trying to import an e00 file (arc/info grid) using r.in.gdal. For example,

GRASS 6.4.0svn (himom):~/Documents/rufus/incoming/wadnr > r.in.gdal input=lewis_dem30.e00 output=lewisdem location=himom2 --verbose
ERROR 4: `lewis_dem30.e00’ not recognised as a supported file format.

from outside GRASS,

Jeff-Hamanns-MacBook-Pro:lewis_dir hamannj$ gdalinfo lewis_dem30.e00

ERROR 4: `lewis_dem30.e00’ not recognised as a supported file format.

gdalinfo failed - unable to open ‘lewis_dem30.e00’.
Jeff-Hamanns-MacBook-Pro:lewis_dir hamannj$

and the file looks like this:

Jeff-Hamanns-MacBook-Pro:lewis_dir hamannj$ head lewis_dem30.e00
EXP 0 /AM/PROCESS/DATASERVICES/LEWIS_DIR/LEWIS_DEM30.E00

Any hints? What kind of file is this, really?

Thanks,
Jeff.

Hey Jeff,

This is a valid file, though not well supported by software other than ESRI. E00 files most commonly hold vector formats, but can be used to contain raster data also. AFAIK, there is no way to import these directly into GRASS, it only supports the vector version with v.in.e00

For this reason, I keep a little ESRI utility around just in case:

http://www.esri.com/apps/products/download/?downloadid=175

It’s a Windows binary, and requires registration, but it works. I’ve successfully run it using Wine on Linux, probably will work on a Mac also. I reads the e00 file and dumps an arcinfo binary grid where you specify.

Hope this helps.

Jamie
