Hi all,
My standard location is a Lambert Conformal Conic (2SP) created using
EPSG 2234. When I receive data from my city GIS system, it arrives (as
a shape file) in a very similar but non-identical projection. I
created a new location based on one of the data files, and re-project
to and

Well, you are running Grass in a different way then... not sure if I
can help. Maybe try the location parameter in r.in.gdal. It's suposed
to create an appropriate location before importing the data...

Hello
I have polygon layer which divides my image into several areas all
contiguous. With the same size, I have a raster image. I want to:
- calculate the most frequent value of the raster inside each polygon;
- the maximum and minimum value inside each polygon
How can this be done in GRASS?
Hamish,
The quick startup has the instruction for switching to the TclTk GUI as g.gui
-ui. I think that should be g.gui gui=tcltk -ui
Otherwise it looks good. The one-page overview is great.

Try using some already existing data for mapped streams, such as the
national hydrography dataset. You can adjust the threshold of the
accumulation until your modeled output is close to already mapped

Hi Hamish,
Thank you for reply.
This command assume that I set up the computational region, I have many
problems with setting region and I recive many errors like

How can I set a region from scratch?

What GRASS version is in there? The OSGeo live contents page says 6.4
rc5, but that can't be true. RC6 would be a shame too, too many bugs
