Hi,
I'm relatively new to GIS and I'm attempting to calculate the slope from a DEM raster of the Adirondack Park.
<Spatial_Reference>NAD_1983_UTM_Zone_18N
<Linear_Unit>Meter (1.000000)</Linear_Unit>
<Angular_Unit>Degree (0.017453292519943295)
I'm having trouble understanding how to determine if I need to change the z-factor from the default "1" and then which z-factor to use if one is needed.
Can anyone lend a hand?
