So, I create a PJ thusly: pj = proj_create_crs_to_crs(NULL, "EPSG:4326", "EPSG:3005", NULL); The from is clearly angular, the to is an albers projection in NAD83. But proj_angular_input(pj, PJ_FWD) Does not return true? Am I misunderstanding the meaning of proj_angular_input or of forward/backward? P
