- PROJ — PROJ 9. 7. 1 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. 7. 1 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. 7. 1 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
- Geodetic transformation — PROJ 9. 7. 1 documentation
Geodetic transformation PROJ can do everything from the most simple projection to very complex transformations across many reference frames
- Quick start — PROJ 9. 7. 1 documentation
Every projection in PROJ is identified by a shorthand such as merc in the above example By using the above projection definition as parameters for the command line utility proj we can convert the geodetic coordinates to projected space:
- Using PROJ — PROJ 9. 7. 1 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
- About — PROJ 9. 7. 1 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
- Cartographic projection — PROJ 9. 7. 1 documentation
This section is devoted to the generic parameters that can be used on any projection in the PROJ library Below is a list of PROJ parameters which can be applied to most coordinate system definitions
