[GRASS-user] profile and tangential curvature negative XY coordinates

[Edgar Pimiento]

Hello all,

I am a new GRASS 6.4 user (1 month). I want to calculate topograhic parameters (profile and tangential curvatures) from a 1-m DEM that has negative XY coordinates (EPSG2446) north -210,000 south -213,000 west -60,500 east -55,500. Resulting rasters have extremely large values.

Is it because of spatial reference? is there a workaournd?

I appreciate any comment. Thank you,
