[GRASS-user] i.landsat.toar problem: Failed to identify satellite

GRASS GRASS user

Hi All,

I’m new to GRASS GIS, but have generally been successful in what I’m trying to do. One problem I’ve come upon is using a metadata file for the i.landsat.toar command. For one particular set of imagery I am working with, I get an error: “ERROR: Failed to identify satellite”

My immediate solution for now was to take metadata that was formatted a bit differently from an image that I downloaded a while back, and replace appropriate fields. But, as I download new Landsat images, that is cumbersome…

I am working on GRASS 6.4.3RC2, which I just downloaded from the main website in the last couple of weeks. I saw this e-mail thread, which makes it seem like this problem should have been solved: http://lists.osgeo.org/pipermail/grass-user/2012-December/066558.html
Do I need to somehow install the new version of the i.landsat.toar command?

My computer is running Windows 7 64bit.

On a side-note, I haven’t been able to install any add-on modules. I’ve tried, using the GUI, and below is what happens.
g.extension.py extension=i.landsat.trim svnurl=http://svn.osgeo.org/grass/grass-addons/grass6
Downloading precompiled GRASS Addons <i.landsat.trim>…
ERROR: GRASS Addons <i.landsat.trim> not found

I’d greatly appreciate any suggestions.
Thank you!

Sincerely,
Mike

Hi Mike,

If I may ask, which Landsat products do you use? TM5 or ETM+ 7 (pre- or
post-2003 for the latter)?

No need to do so.

I am working on GRASS 6.4.3RC2, which I just downloaded from the main
website in the last couple of weeks.

There were some issues but they are all fixed as far as I can tell (thanks to
Jorge Tizado). I have tested myself the most recent versions of
i.landsat.toar (under Linux, for grass64 and grass70) and they work(ed) with
both the old and the new metadata files that come along with the Landsat bands.

I saw this e-mail thread, which makes it seem like this problem should have
been solved:

I guess so.

My computer is running Windows 7 64bit.

So the actual question, if I don't miss anything, is: how to get the most
recent version of i.landsat.toar compiled and running for Windows (7, 64-bit)?

Here are "latest" binaries provided by Martin Landa:
<http://wingrass.fsv.cvut.cz/grass64/&gt;\. This should be sufficient.

If not, here is a pointer to compile all the stuff from scratch (although I
haven't compiled GRASS for Windows so far):
<http://trac.osgeo.org/grass/wiki/CompileOnWindows&gt;\.

Note, you can get the latest SVN source code version -- it's described in the
sub-section: "GRASS 6.4.svn (releasebranch_64)".

Hope this helps you. If it is too much for you (compiling the staff from
scratch) then maybe someone has already done that and can assist?

Best, Nikos

Hi Nikos,

Thanks for the help! I just downloaded and installed the most recent Windows binaries, and i.landsat.toar worked perfectly with my data (Landsat 5 by the way).

Also, I’m now able to install add-on modules.

Thanks again!
Mike
