Hi,
I am writing to python code to calculate the length (in metres) of a
degree of longitude at a certain degree of latitude. I would like to
take various ellipsoid in mind (WGS84, GRS80, Clarke 1866...). The goal
is to find the right scale (or z factor) when making slope or shade
raster models when x and y are in long/lat and z in feet or meters. Can
someone point me in the right direction to do this in using Proj? Is
Proj the best option for this?
Thanks,
Nicolas
