Cassini Soldner (Kenya) in QGIS

Post by ouma »

I've successfully used the following custom projection to plot Cassini coordinates centered on Longitudes 35 and 37 respectively without any errors;

Code: Select all

+proj=cass +lat_0=0 +lon_0=35 +x_0=0 +y_0=0 +a=6378350.87 +rf=294.26 +towgs84=-306,-6,-101,0,0,0,0 +units=m +no_defs

Code: Select all

+proj=cass +lat_0=0 +lon_0=37 +x_0=0 +y_0=0 +a=6378350.87 +rf=294.26 +towgs84=-306,-6,-101,0,0,0,0 +units=m +no_defs
This works for cassini in meters, though the same can still work for measurements in feet so long as you define "a" and "+units" in feet.


Your thoughts?
