[GRASS-user] [GRASSLIST:1183] how to rotate raster in GRASS ?

[Pierluigi De Rosa]

Dear GRASS users,

I have a strange problem to solve, I'm using a program called CAESAR (GNU Project) to model river processes (http://www.coulthard.org.uk/).
This program nedds an ASCII input elevation file where the main direction of floe is from left to right, so the catchment exit point has to be in the right hand of the DEM.

Does Anyone know how is possible to rotate a raster in GRASS?

Thanks

Pierluigi
