Greetings
I have used r.statistics to calculate the sum of a cover map based on a
base map. When I use the Query tool I get these:
598666.544966|9159452.159237||3996|7108
The first two corresponds to Geographic Location the third Base map
clump ID and the last one it corresponds to the value o
Dear all,
I'm a newbie in grass GIS so I'm sorry, if this question is very simple. Has
anyone any idea how to create a raster map including only the information of
the latitude and longitude of each cell? I want to write a script to compute
the solar elevation angle for a large area and time range
Do your cells contain some other information (i.e. the variable you want
to create raster for) apart from lat and long?
What format is your lat/long file? text or some sort of a vector?
Do you want to directly convert the values to cells with raster values or
having some interpolation and TINs?

Hello all users
I try to use GRASS-6.4.0RC6 under Fedora8. I want to configure GRASS for python
so I run the following instruction:
./configure --with-python=/usr/bin/python2.5-config

then I run 'make', But I encounter the following errors:

Hello,
1) remove GRASS from ld.config
2) download GRASS 6.4.1 snapshot or 6.5
3) make fresh compilation there
4) if fails - upload full failing part log somewhere.
If it still fails, then issue migh be related to Fedora packed lib

Hello,
first great thanks to you William! My GRASS 7.0 is no perfectly running
on my Mac 10.6.6.
Now I want to install the r.stream addon. I tried with
g.extension extension=r.stream

but I failed...
So what do I ha
No I don't have any other information, lat and long are variables in my

my script. I want to have cells that contain only lat long as information.
At the moment I don't have any data with the coordinates because I wanted to

Markus,
Wonder why/how.
You may want to try it stand-alone to see why (to catch the error message).
Also
Don't know how to do this: from what directory and using what command line
syntax?
ldd `which avcimpo

You could modify line 178 in:
/usr/local/grass-6.5.svn/scripts/v.in.e00
and remove this part:

No linux-gate.so.1.
I think that's correct.
Yes, linux-gate is a kernel-added lib

Dear list,
I have found problems with d.barscale mentioned in bug tracker only for
grass 7.
When trying to draw a scale bar using PNG driver in grass6.4.svn on
windows7 (couple of months old -- it is the last version I have that
does not need to delete vectors twice, see
http://trac.osgeo.o
Antonio,
since the calculated statistics are stored as labels in the output map, you
have to use the @ operator in the mapcalc formula in order to access the
labels instead of the clump categories, in your case.
Regards,
Christian.

I fully agree - but we can change only in GRASS 7 for backward

Markus,
As long as I can continue working from the command line in 7 I'll be
happy. Shell scripts have worked so far and I do know some python so I can
work with that, too
Context: I have a postgres table with > 110K rows of permitted wells.
Among the columns are lat, lon, utm_easting, and utm_northing; for example:
latitude | longitude | utm_easting | utm_northing

41.04 | 117.31 | 473829.

tom,
The magnitude of the values is also indicative; for the NAD27 values in
feet they'd be much larger

Hate to be a wet blanket, but both NAD27 and NAD83 UTM coordinates are supposed
to be in meters. The False Easting for the UTM zones are defined to be 50m
regardless of datum. So, the presence of meters in your DB is not a solid
indication that it is in NAD83. As the lat/long in you're file
