you surely already know that; but I specify for others reading that topic.
Note that:

1. if your projection is based on distance (easting and northing), the 
coordinates values must be in meters.
2. the elevation and maximum distance must be measured in meters, even if 
you use geographical coordinates (longitude/latitude)
3. the buffer parameters must be in the same units as the raster 
coordinates.

Cheers,

Marco
