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

evaluation criteria]. Michael Smith has [ expressed willingness to mentor
the project during the incubation process

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.
