Hi,
Those who want to test their mental limits can read the ticket:

-Jukka Rahkonen-
Please help me with something potentially important. The documentation for
gdaldem slope says “If the horizontal unit of the source DEM is degrees (e.g
Lat/Long WGS84 projection), you can use scale=20 if the vertical units are
meters” but I don’t think this works very far away from the equa
