Reading https://proj.org/en/9.2/operations/projections/calcofi.html I became curious if I could emulate it using cs2cs, or other projections, like:
> The coordinate system is based on the Mercator projection with units > rotated -30 degrees from the meridian so that they are oriented with the +proj=omerc +alpha=-30 > coastline of the Southern California Bight and Baja California. Lines > increase from Northwest to Southeast. A unit of line is 12 nautical miles. +units=kmi +k_0=.083333 > Stations increase from inshore to offshore. A unit of station is > equal to 4 nautical miles. +units=kmi +k_0=.25 #for a second run > The rotation point is located at line 80, station 60, +x_0=80 +y_0=60 > or 34.15 degrees N, 121.15 degrees W, +lonc=-121.15 +lat_0=34.15 Alas, if it were that simple, someone would have mentioned it on https://github.com/OSGeo/PROJ/issues/135 . _______________________________________________ PROJ mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/proj
