How to access projection-factors in 4.8 (without projects.h)?

Hi, I just read that the projects.h header is no longer available (publicly). Currently, I use projects.h to calculate the factors.k from the polar-stereographic projection. Polar-stereographic projections can be defined by 'lat_ts' or by 'k', and up to 4.7, I was able to access those easily, e.g. when translating from a proj-projection to a projection in FGDC: att["scale_factor_at_projection_origin"] = factors.k; This functionality is available in 'proj -V' (which still requires projects.h) but not in the public API proj_api.h I think, as long as the commmand-line interface still requires 'projects.h', not all necessary functionality is included in proj_api.h Best regards, Heiko _______________________________________________ Proj mailing list Proj <at> lists.maptools.org http://lists.maptools.org/mailman/listinfo/proj
