-The .prj file contains a text description of a coordinate system in the OpenGIS Well-Known Text (WKT) format.
+#redirect[[PRJ]]
-Siehe auch [[GIS-Datei-Format]].
-Note that this .prj format is the same as the .prj format used by the most recent versions of ESRI software, but different from the .prj format of older ESRI software.
-Developers may find it useful to use free libraries such as [[OGR]] (or indirectly, GDAL).
