The status of contributors is shown at: 39https://github.com/OSGeo/proj.4/blob/master/AUTHORS. 40PROJ uses the MIT license. The software was initially released by the USGS 41in the public domain. When Frank Warmerdam took over the development of 42PROJ it was moved under the MIT license: https://proj.org/about.html. 43 44Both PROJ and GDAL provide metadata files derived from other providers, and 45licensed under varying conditions, mostly precluding the arbitrary 46modification of metadata elements, most of which give coordinate reference 47system parameter values. These files are copied into CRAN Windows and OSX 48binary packages. Their provenance is not fully documented, but some lists are 49available, for example: https://github.com/OSGeo/proj.4/blob/master/nad/README. 50Work is in progress to link the provided data files to their licenses, such as: 51http://www.epsg.org/Termsofuse.aspx. Additional non-free metadata files may 52be added as shown in: https://proj.org/resource_files.html. 53 54
