TYPE | PARAMETERS |
|---|---|---|
| Geographic Coordinate System (latlong) | 1 | PROJ_ALPHA, PROJ_BETA, PROJ_GAMMA, XCENT, YCENT are unused and set to 0. Coordinate units are degrees, -180.0 < X,Y <= 180.0 Note that Western hemisphere longitudes and Southern Hemisphere latitudes are taken to be negative. |
| Lambert Conic Conformal - 2SP parameters (lcc) | 2 | PROJ_ALPHA is lat_1 which is the latitude of first standard parallel. PROJ_BETA is lat_2 which is the latitude of second standard parallel. PROJ_GAMMA is lon_0 which is the longitude of false origin. X_CENT is lon_0 which is the longitude of false origin. y_CENT is lat_0 which is the latitude of false origin. Values of x_0 and y_0 are not defined in this software |
| Mercator 1SP (merc) | 3 | PROJ_ALPHA is lon_0 which is the natural origin. PROJ_BETA is k_0 which is the scale factor at natural origin. PROJ_GAMMA is x_0 which is the False Easting. X_CENT is y_0 which is the False Northing. The rest of parameters are unused and set to 0. |
| Mercator 2SP (merc) | 4 | PROJ_ALPHA is lat_ts which is the latitude of first standard parallel. PROJ_BETA is lon_0 which is the longitude of natural origin. PROJ_GAMMA is x_0 which is the False Easting. X_CENT is y_0 which is the False Northing. The rest of parameters are unused and set to 0. |
| Stereographic (stere) | 5 | PROJ_ALPHA is lat_0 which is the latitude at projection center. PROJ_BETA is lon_0 which is the longitude at projection center. PROJ_GAMMA is x_0 which is the False Easting. X_CENT is y_0 which is the False Northing. The rest of parameters are unused and set to 0. |
| Universal Transverse Mercator for the Northern Hemisphere (utm) | 6 | PROJ_ALPHA is the UTM zone, considered as a DOUBLE. PROJ_BETA is x_0 which is the False Easting. PROJ_GAMMA is y_0 which is the False Northing. The rest of parameters are unused and set to 0. For the southern hemisphere UTM unblock the line: sprintf(args[i++],"%s","+south") in mims_spatl_proj.c file |
| Polar Stereographic (stere) | 7 | PROJ_ALPHA is lat_ts which is the latitude at natural origin. PROJ_BETA is lon_0 which is the longitude at natural origin.

| Transverse Mercator (tmerc) | 8 | PROJ_ALPHA is lat_0 which is the latitude of natural origin. PROJ_BETA is lon_0 which is the longitude of natural origin PROJ_GAMMA is k which is the scale factor at natural origin. X_CENT is x_0 which is the False Easting. Y_CENT is y_0 which is the False Northing. |
