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.<br><br>Is it because of spatial reference? is there a workaournd?<br><br>I appreciate any comment.
