How should the CF 1SP version be converted to OGC WKT, and vice-versa? Currently the driver imports an AEA with 2 identical std_parallels. 35 * LCC : The OGC WKT 'Lambert_Conformal_Conic_2SP' maps clearly to LC in CF-1 with 2 std parallels. The CF-1 spec claims that a 1SP version can be used, but it doesn't include a 'scale_factor' as does the OGC WKT 'Lambert_Conformal_Conic_1SP'. Is there a way to do this conversion?35 * LCC : The OGC WKT 'Lambert_Conformal_Conic_2SP' maps clearly to LCC in CF-1 with 2 std parallels. The CF-1 spec claims that a 1SP version can be used, but it doesn't include a 'scale_factor' as does the OGC WKT 'Lambert_Conformal_Conic_1SP'. Is mapping std_parallel_1 maps to latitude_of_origin and setting scale_factor=1 correct? (see bug #3324) 36 36 * CEA : The CF-1 conventions claim this can be encoded with a 'scale_factor_at_projection_origin' alternative to standard parallel - how would this conversion be done back from OGC WKT? 37 37 * PS : This projection's parameters in CF-1 are quite unusual, and significantly different from http://www.remotesensing.org/geotiff/proj_list/polar_stereographic.html. In particular finding a CF-1 equivalent for 'latitude of natural origin' is proving difficult.
