-----------------------+------------------
 The PROJ project would like to formally request incubation into OSGeo. The
 incubation questionnaire is filled out below. I believe the project
 fullfils all the
 [https://www.osgeo.org/about/committees/incubation/evaluation/ project
 evaluation criteria]. Michael Smith has [ expressed willingness to mentor
 the project during the incubation process
 https://lists.osgeo.org/pipermail/proj/2019-March/008289.html].

 1.  Please provide the name and email address of the principal Project
 Owner.

     Kristian Evers <[hidden email]>

 2.  Please provide the names and emails of co-project owners (if any).

     Howard Butler, [hidden email]
     Frank Warmerdam, [hidden email]

 3.  Please provide the names, emails and entity affiliation of all
 official committers

 Efficiency
     Howard Butler, [hidden email], Hobu Inc.
     Charles Karney, [hidden email], SRI International
     Thomas Knudsen, [hidden email], Danish Agency for Data Supply and
 Efficiency
     Even Rouault, [hidden email], Spatialys
     Frank Warmerdam, [hidden email], Planet Labs Inc.

 4.  Please describe your Project.

     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.

     PROJ includes command line applications for easy conversion of
 coordinates from
     text files or directly from user input. In addition to the command
 line
     utilities PROJ also exposes an application programming interface, or
 API in
     short. The API lets developers use the functionality of PROJ in their
 own
     software without having to implement similar functionality themselves.

     PROJ started purely as a cartography application letting users convert
 geodetic
     coordinates into projected coordinates using a number of different
 cartographic
     projections. Over the years, as the need has become apparent, support
 for datum
     shifts has slowly worked its way into PROJ as well. Today PROJ
 supports more
     than a hundred different map projections and can transform coordinates
 between
     datums using all but the most obscure geodetic techniques.

 5.  Why is hosting at OSGeo good for your project?

     PROJ is already a community member of OSGeo and used by most, if not
 all,
     C/C++ based OSGeo projects. A foundational library such as PROJ should
 benefit
     from the full support of OSGeo, allowing the project to support it's
 downstream
     brothers and sisters better.

 6.  Type of application does this project represent(client, server,
 standalone, library, etc.):

     Library, command line utility.

 7.  Please describe any relationships to other open source projects.

     PROJ is a dependency for most, if not all, of the C/C++ based OSGeo
 projects.
     Additionally, a number of projects (likely in the hundreds) from
 outside the realm of OSGeo depends on
     PROJ for coordinate transformations

 8.  Please describe any relationships with commercial companies or
 products.

     A few of the PSC members represent companies that has commercial
 interest in PROJ.
     Either because they rely on the software in their production or
 because they offer
     development on PROJ as a service in their consultancy business.

 9.  Which open source license(s) will the source code be released under?

     PROJ is released under the MIT license. Previous to version 4.3 of
 PROJ
     the code was considered public domain by the United States of America.

     https://github.com/OSGeo/proj.4/blob/master/COPYING

 10. Is there already a beta or official release?

     Yes, multiple. At the time of writing the most recent version is
 6.0.0.

 11. What is the origin of your project (commercial, experimental, thesis
 or other higher education, government, or some other source)?

     Government. PROJ was originally developed by Gerald I. Evenden at the
     USGS in the 1980's. Today PROJ is used by actors in both higher
 education,
     government and the private sector.

 12. Does the project support open standards? Which ones and to what
 extent? (OGC, w3c, ect.) Has the software been certified to any standard
 (CITE for example)? If not, is it the intention of the project owners to
 seek certification at some point?

     PROJ support the Well-Known Text and Well-Known Text2 described in the
 ISO 19111 standard
     on "Referencing by coordinates". I am not aware of any official
 certification. To the
     best of my knownledge PROJ is the first application to implement WKT2,
 so it can in some
     sense be regarded as a reference implementation.

 13. Is the code free of patents, trademarks, and do you control the
 copyright?

     Yes.

 14. How many people actively contribute (code, documentation, other?) to
 the project at this time?

     Releases typically has between 10 and 20 contributors. Usually, the
 majority of
     the work is done by a handful of regular contributors.

 15. How many people have commit access to the source code respository?

     7.

 16. Approximately how many users are currently using this project?

     The number of direct users of PROJ is likely rather low, but when
 counting indirect
     users, such as users of GDAL, PostGIS and QGIS, the number is likely
 in the millions.

 17. What type of users does your project attract (government, commercial,
 hobby, academic research, etc. )?

     Government, commercial, academia.

 18. If you do not intend to host any portion of this project using the
 OSGeo infrastructure, why should you be considered a member project of the
 OSGeo Foundation?

     N/A - PROJ already uses OSGeo infrastructure.

 19. Does the project include an automated build and test?

     Yes. PROJ include both autools and CMake build systems, has a test
 coverage of about 85%.
     Tests are run on a number of CI targets for each commit to the master
 branch.

 20. What language(s) are used in this project? (C/Java/perl/etc)

     C and C++.

 21. What is the dominant written language (i.e. English, French, Spanish,
 German, etc) of the core developers?

     English.

 22. What is the (estimated) size of a full release of this project? How
 many users do you expect to download the project when it is released?

     The 6.0.0 release is 2.3MB. The accompanying datum grid package is
 6.3MB.
     Additionally, the optional grid packages for Europe and North America
 are
     both around 20MB. The optional grid package for Oceania is 70MB.

Comment (by kbevers):

 A few updates regarding the use of the EPSG registry:

 12. Does the project support open standards? Which ones and to what
 extent? (OGC, w3c, ect.)
     Has the software been certified to any standard (CITE for example)? If
 not, is it the
     intention of the project owners to seek certification at some point?

     PROJ support the Well-Known Text and Well-Known Text2 described in the
 ISO 19111 standard
     on "Referencing by coordinates". I am not aware of any official
 certification. To the best
     of my knownledge PROJ is the first application to implement WKT2, so
 it can in some sense
     be regarded as a reference implementation.

     PROJ support the EPSG registry more or less in it's entirety. No
 certification is available
     but the IOGP (the organization behind the EPSG registry) offers the
 GIGS test suite that
     allows projects to determine their compliance with the intended use of
 the registry. PROJ
     is currently partially compliant (~80%).

 13. Is the code free of patents, trademarks, and do you control the
 copyright?

   Yes. Except for the EPSG registry which is included in the PROJ source
 distribution. The
   registry is available on a "free to use" basis as long as the original
 data is not modified.
   The terms of use are available here: http://www.epsg.org/TermsOfUse.aspx

 Replying to [comment:1 kbevers]:
 > 13. Is the code free of patents, trademarks, and do you control the

 >   Yes. Except for the EPSG registry which is included in the PROJ source
 distribution. The

 data is not modified.
 >   The terms of use are available here:
 http://www.epsg.org/TermsOfUse.aspx

 Not allowing modification makes it non-compliant with the
 [https://opensource.org/osd-annotated Open Source Definition] (OSD) and
 [https://www.debian.org/social_contract#guidelines Debian Free Software
 Guidelines] (DFSG) on which the OSD is based. This risks making the entire
 geospatial stack dependent on a non-free library.

 The [http://www.epsg.org/TermsOfUse.aspx EPSG TOU] requires that modified
 data is not attributed to the EPSG Dataset when the modifications fall
 outside of the permitted list:

 > vii. No data that has been modified other than as permitted in these
 Terms of Use shall be attributed to the EPSG Dataset.

 As long as the data is not attributed to the EPSG dataset, the terms of
 the MIT license used for PROJ can also cover the SQL files and resulting
 database.

 Both the OSD & DSFG permit only allowing modifications when a different
 name is used, to dissociate the original author from the modified work:

 > **4. Integrity of The Author's Source Code**
 >
 > The license may restrict source-code from being distributed in modified
 form **only** if the license allows the distribution of "''patch files''"
 with the source code for the purpose of modifying the program at build
 time. The license must explicitly permit distribution of software built
 from modified source code. The license may require derived works to carry
 a different name or version number from the original software. (''This is
 a compromise. The Debian group encourages all authors not to restrict any
 files, source or binary, from being modified.'')

 This has allowed PROJ 6.0.0 to stay in the main component of the Debian
 archive.

 Just for context, two minors corrections on the following sentence:

 > PROJ support the Well-Known Text and Well-Known Text2 described in the
 ISO 19111 standard on "Referencing by coordinates". I am not aware of any
 official certification. To the best of my knownledge PROJ is the first

 Actually the WKT 2 format is specified by ISO 19162, not ISO 19111. The
 later is rather the conceptual model from which PROJ 6 API is derived.

 PROJ is not the first application to implements WKT 2. The open-source
 [https://github.com/Esri/ogc-crs-wkt-parser ESRI prototype on GitHub] is
 the first ISO 19162 (WKT 2) implementation I'm aware of.
 [http://sis.apache.org/ Apache SIS] came next in 2017. PROJ 6 is third to
 my knowledge. However PROJ 6 may be the first project to implement the
 WKT2 update published in 2019, but this is a relatively minor revision of
 ISO 19162:2015 compared to WKT 1.

 Note also that the "PROJ support the Well-Known Text" sentence is a little
 bit ambiguous. Actually PROJ supports a WKT 1 dialect which is not the
 standard one as defined in OGC 01-009 (the standard mandated by Geopackage
 among others). For EPSG::4807 CRS, the PROJ interpretation of WKT 1 has an
 offset of 17 km at the latitude of Paris compared to the OGC 01-009
 interpretation.
