This page is intended to eventually contain information on all the projections supported by PROJ.4. For now however it is a repository for information on new projections added to since Gerald's PDF documentation was created in the 1990's. As such it will tend to have relatively esoteric projections rather than the most common.
- proj=geos Geostationary projection
- proj=healpix HEALPix
- proj=natearth Natural Earth
- proj=rhealpix rHEALPix
Please add new projection documents with a page name that is exactly "proj=projectionname". Add projections in alphabetic order. The descriptive text should ideally be the same long name reported by "proj -lp" for the projection (from the PROJ_HEAD directive in pj_list.h).
