- PROJ — PROJ 9. 6. 2 documentation
PROJ is a generic coordinate transformation software that transforms geospatial coordinates from one coordinate reference system (CRS) to another This includes cartographic projections as well as geodetic transformations
- Download — PROJ 9. 6. 2 documentation
See Installation for information on how to get pre-built packages of PROJ Documentation in PDF and zipped HTML can be downloaded using the flyout menu on the left side of the browser window
- Installation — PROJ 9. 6. 2 documentation
The simplest way to install PROJ on Windows is to use the OSGeo4W software distribution OSGeo4W provides easy access to many popular open source geospatial software packages
- Quick start — PROJ 9. 6. 2 documentation
Coordinate transformations are defined by, what in PROJ terminology is known as, "proj-strings" A proj-string describes any transformation regardless of how simple or complicated it might be
- About — PROJ 9. 6. 2 documentation
PROJ is a generic coordinate transformation software that transforms geospatial coordinates from one coordinate reference system (CRS) to another This includes cartographic projections as well as geodetic transformations
- Geodetic transformation — PROJ 9. 6. 2 documentation
Geodetic transformation PROJ can do everything from the most simple projection to very complex transformations across many reference frames
- Using PROJ — PROJ 9. 6. 2 documentation
The main purpose of PROJ is to transform coordinates from one coordinate reference system to another This can be achieved either with the included command line applications or the C API that is a part of the software package
- FAQ — PROJ 9. 6. 2 documentation
Generally PROJ will accept coordinate reference system descriptions in the form of WKT, WKT2 and PROJ strings If you are able to describe your desired CRS in either of those formats there's a good chance that PROJ will be able to make sense of it
