# Robinson

Name | Robinson EPSG Code |
GeoTIFF Code | CT_Robinson (23)
OGC WKT Name | Robinson
Supported By | GeoTIFF, PROJ.4, OGC WKT

### Projection Parameters

Name | EPSG # | GeoTIFF ID | OGC WKT | Units | Notes Longitude of projection center | 2 | ProjCenterLong | longitude_of_center | Angular |
False Easting | 6 | FalseEasting | false_easting | Linear |
False Northing | 7 | FalseNorthing | false_northing | Linear |

### Notes

Intergraph files use NatOriginLat/Long instead of CenterLat/Long. Earlier discussions of Robinson don't include a scale, and CenterLat, but Intergraph's files do. I have omitted them from the above list, but I imagine they may be added back.

I also get very substantially different results from PROJ.4's Robinson support, and PCI (GCTP)'s results as noted in Random Issues.
