[Freegis-list] Clipping raster with OpenEV

[Rajkumar Singh]

Hi,

I'm not sure if this question was answered on the list before so please 
forgive my ignorance. I did a search on Google but didn't find anything 
substantial either. I'm trying to clip a DEM (GTOPO30) using a box 
defined by two pairs of latitude/longitude coordinates. Is there anyway 
to do it without having to define the ROI by drawing a box? Or is there 
any other free software I can use besides GRASS? If there are any 
tutorials online please point me to them. Thanks for all responses.

Regards.

Raj
