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 Here you can download current and previous releases of PROJ We only supply a distribution of the source code and various resource file archives 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 Current
Quick start — PROJ 9. 6. 2 documentation The simplest case is projection of geodetic coordinates This section focuses on the simpler cases and introduces the basic anatomy of the proj-string The complex cases are discussed in Geodetic transformation A proj-strings holds the parameters of a given coordinate transformation, e g
Geodetic transformation — PROJ 9. 6. 2 documentation In PROJ, two frameworks for geodetic transformations exists, the PROJ 4 x 5 x cs2cs pj_transform() framework and the transformation pipelines framework The first is the original, and limited, framework for doing geodetic transforms in PROJ
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 What happened to PROJ 4? Who uses PROJ ? Which file formats does PROJ support? The command line applications that come with PROJ only support text input and output (apart from proj which accepts a simple binary data stream as well) proj, cs2cs and cct expects text files with one coordinate per line with each coordinate dimension in a separate
