I need to compare two projections definitions say
projPJ p1 and projPJ p2
in order to compare them I'm currently getting their pro4 string
definition, using pj_get_def, and comparing the two proj4 strings.
I wonder if there is a faster way to compare them.
I noticed there is an undocumented pj_compare_datums function in
proj_api.h, but I'm not sure it can be used for that purpose.
