RC5 is quite old (with few days should be released RC7). In any case
you can always use TCL/TK digitizer [1]. wxGUI vector digitizer can be
compiled manually, you just need to use specific version of swig

I can use the grass64RC5 digitizer with good results?

I haven't read your message carefully. The wxGUI vector digitizer has
been disabled few weeks ago globally for all platforms. It should be
fixed in 6.4.1, till this time please use TCL/TK v.digit.

wxGUI vector digitizer is not working on MS Windows. Use v.digit

Andrew,
I think your problem is associated to the cats in vector, not the raster
map.
Do you have a cat column in the polygon map?

Okay, so I found out more information. I reclassed the raster layer to give
myself some categories; however, when I tried to run v.rast.stats I got an
error saying "No categories found in raster map"
Your help is much appreciated.

Hi Everyone,
I would like to create a raster map of temperature values using v.surf.idw and
calculate the median temperature value for each state/province in North
America. I currently have a point shapefile of temperature values covering all
of North America, a North American area shapefile (

Yes it is quite possible.
You may want to take a look at Lizarazo and Elsner paper in
International Journal of Remote Sensing entitled Fuzzy Segmentation for
Object-based Image Classification. It is my understanding that the
methodology they describe was done almost entirely within R.

Hi All
First of all sorry for cross posting.
If seems that final releasing of new version GIS GRASS 6.4 is matter of few
days. I would like to encourage you to make translations into your language
as soon as possible.
4 days ago were all .po files updated and we can start translate almost

I'm trying to extract building outlines from LIDAR data. I have both a DSM

from these.
I now want to extract building footprints from the DSM i.e. create a

Hello,
I would like to calculate the average slope by square kilometer for a giving

to create a grid of square of 1 km² and to calculate for each square the
average slope.
My main problem is that I don"t have any idea h
