- 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
- 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
- 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
- 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
- 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
- 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
- Universal Transverse Mercator (UTM) — PROJ 9. 6. 2 documentation
Added in version 7 1 Selects the algorithm to use The hardcoded value and the one defined in proj ini default to poder_engsager, that is the most precise one
