    Description

      The Cassini-Soldner projection looks like the Transverse Mercator projection and was more extensively used in past centuries. It would still be useful to port it for historical data. The code in Geotk was originally started by an external contributor. We need to rewrite the formulas for the coordinate projection and inverse projection, using the EPSG guide.

      Note that the formulas for the projection derivative can be ported as-is.
