Hi,
I have some troubles managing 0, null values and r.colors. I just want
to extract a particular habitat category from a Global Land Cover 2000
raster into a raster of presence/absence (and NULL value for ocean and
waterbodies)
This makes the following:

HI! ALL
I have been trying to generate a lake feature from dem and seed raster files
using r.lake, this is information below.
The areas are not created as values can be
I'm having two problems when exporting the output of r.stream.order
to a shapefile.
I have attached the created table (saved in my setup in sqlite) to
the 'streams' map thru layer 2. Then
v.db.select streams layer=2
shows all the details of strahler order,

Hello,
please check following things:
1) water level at seed point/area is above terrain (provided DEM);
2) seed point/area is located within current computational region
(just run g.region rast=my_dem before r.lake);
3) seed point/area has values 0 (quirk of current implementation).
Good luck!
OK solved. I figured out that it was actually a problem in the units i used
in the input maps.

Hi,
Is there a way to calculate automatically the annual radiation in r.sun
because the algorithm calculates one day at a time.
Yes, see (minimal modifications will be needed to cover the full year):
A few more details regarding v.out.ogr when layer=2
I see this ticket, possibly similar:
