I am new to Grass after spending the last 12 years working on an
infernal Windows machine running Arc and ArcGIS. I am now running SuSE
Linux 10.0 on a Dell with an Intel P4, and have Grass 5.0 installed. I
installed gdal 1.3.1 from the SuSE 9.3 RPMs posted on the Hannover Grass
website. My problem is when I try to import lidar data formatted as Arc
grids. Grass sends me the following error:
ERROR 4: '/catfish_sm' does not exist in the file system and is not
recognised as a supported datset name.
I get the same error when trying to import ascii DEMs (USGS DEMs).
Anyone have any hints to send me down the correct path? Wrong
installation of gdal?? Path not set correctly?? Many thanks ahead of
time for your help. Cheers.....Brian Sherrod

hey congrats on the jumping of ship! i'ma long time arc user moving
as far away as possible and into GRASS/QGIS. this is the future of
GIS before us.
sorry i cant help with your problem, but I would recommend upgrading
to at least versin 6, because there is vector topology, which you know
is important from a/i coverages.

Brian,
M S is right. But if you really need to stay with 5.x line, use the
Grass 5.4, or even better the 5.5, which is available only in CVS
currently. Those have many fixes compared to 5.0. Say if you can
reproduce your error using them.

When using gdal to import arc grids you need to import the w001001.adf
(the BIG file) file. (Inside the grid folder). Maybe that will fix it.

I'm a pretty new user my self but I will try to answer your question. When I
import and export ESRI grids I do it as ascii files - GRASS doesn't seem to
read the GRIDs directly - if it does, somebody please tell me how. So to
import an ESRI GRID, I export the GRID to ascii and use r.in.arc to import it.
Similar with r.out.arc, I export it from GRASS with an ascii file extension
and then import the ascii into ArcGIS. Using this method, the rasters are
properly configured - ie. no offset because of the difference in the way
raster and pixel coordinates are stored.
If anyone has a better way, I'd be curious to hear it.
Thanks,
Kessie.

r.in.gdal
writing to ESRI binary grid is not possible tough, only to ASCII grid
with r.out.arc
. So to
import an ESRI GRID, I export the GRID to ascii and use r.in.arc to import it.

There won't be an offset in case of r.in.gdal too. However, please note
that as data cells in ESRI grids are often not alligned to cell
resolution, you might like know this: https://intevation.de/rt/webrt?serial_num=3961
