Hi All,
I’m a beginner user of Grass GIS (of course for GIS) and I want to know if it’s possible to create a relevant elevation and aspect raster maps for a specified location. If it’s possible, can you explain how to do that? Anyways have a good day everyone.

Hi Vidura,
It will be easier to help if you provide a more detailed description of your problem and what you want to achieve. If what you need is slope and aspect, the module you need is r.slope.aspect. This module needs an elevation map as input.
HTH,
Vero

I will add that we need a definition of 'location.' Do you mean one point
or a defined area such as a drainage basin?

Hi all,
First of all, I must say sorry for my immature question. As I stated before I am a novice user. It took me a lot of time to find that elevation files can be directed from the internet. Silly me thought I can create those files from GRASS GIS itself. Anyways I thank everyone, who spend their time in solving my problem. Have a nice day.

Hi All,
Thank you very much for the reply. I will explain what I want to do with GRASS GIS. In my university research, I use Wildfire behavior modeling module. So in the process, I want to recreate wildfire happened in Los Padres National Forest, CA. So following are the things I need to know how to do,
create the map for the location specified.
generate the elevation raster file from that map.
generate the aspect raster file from the map.
generate the aspect slope file from the map.
I attached some sample files provides by GRASS in the demo data. I need these data to run the fire behavior model.
Have a nice day!!
