Hi Thanks.
How do I project the GTOPO30 data to get a specific region using coordinates, say I need the region within these coordinates: Upper Left (18.2987501, -33.6795831) Lower Right (19.1712501, -34.0145831) On Tue, Jul 13, 2010 at 4:20 PM, Markus Neteler <[email protected]> wrote: > On Tue, Jul 13, 2010 at 1:19 PM, Sandile Gumede <[email protected]> > wrote: > > Hi, > > > > Thanks for the suggestions.
