Have you looked into GDAL's "AIG -- Arc/Info Binary Grid" format
description?

Stefan,

  I found an old web page that used the w001001.adf as it is supposed to

r.in.gdal -o --overwrite

Hi Rich,

There should be a "dblbnd.adf" file in the ESRI grid directory. Please try that 
to import the data. So:

r.in.gdal -o --overwrite
input=Bare_Earth/bh45122c3/dblbnd.adf output=bare_earth

Hope that helps.

Cheers
Stefan

Subject: [GRASS-user] Problem importing ESRI grid file (.adf)

   I have several LiDAR files from a state agency I want to import into 
grass75. For one file I've used this command:

r.in.gdal -o --overwrite
input=Bare_Earth/bh45122c3/w001001.adf output=bare_earth

and get the output in the attached .png.

   The Bare_Earth/ directory, as a compressed tarball, is 11.3M so I've put a 
copy in the public directory of my dropbox account. If I've done this correctly 
you can download a copy using this URL:

Re: [GRASS-user] v.class.mlR Error

[Jamille Haarloo]

Hello Moritz,

This time I asked a vector to be created with the stats and used this to
extract training polygons in QGIS and imported the training map in GRASS.
I had to do some interventions regarding the column names to make sure they
are the same except for the class.
I still get an error, and the only thing I could trace is the fact that
values are missing in some rows  for both vectors. I am not sure if I
should correct this/ retry it all.

This is the command output:

  I have LiDAR files in two ESRI formats and don't know which would be the
better one to use: .shp and .adf.

  My research taught me that .adf is Amiga Data File, and I thought that
Amiga died several decades ago. Seems that ESRI is using that format for
some reason and it does not appear to be supported by gdal.

  The directories with the adf files also contain .dat, .nit, and .dir
files and come in three versions: bare earth, highest hits, and intensity.

  My use of these DEMs is for hydrological modeling, including storm runoff
with times of concentration for specified 24-hour storm hydrographs. So, I
want to become informed about my choices. Recommended readings also
appreciated.

Yes, weights must be positive.

A zero weight means that all values in this map are ignored. Zero weights can 
also cause the sum of weights to be zero, leading to division by zero and 
finally to +inf / -inf as a result

Thank you Markus for your reply.
I would think it would have been interesting to use zero as weight on some 
raster in order to use (or not) them depending on the context. For my purpose i 
will use a value next to zero.
Thanks again
Frank

Re: [GRASS-user] i.gensig - multiple signatures into a single file for i.maxlik

Hi Paul,

Please keep discussions on the list.

What do you mean by "out of action" ? And why do you need the layer
manager while using the class manager (we are speaking about
g.gui.iclass [1], here, or ?) ? You can directly create different
classes in one run of this tool. You can save your training areas as a
one single vector map containing all areas of all classes and/or
create the signature file (containing all classes). Check out the video
tutorial linked at [2].

If you have different classes in different vector maps, you can combine
them using v.patch, rasterize the result using v.to.rast (or possibly
v.to.rast on each and then r.patch) and use then use the resulting
raster map as input for i.gensig. It will automatically create the
signature file combining all classes.
