<h1>PROJ.4 - Cartographic Projections Library</h1>
This web page relates to the PROJ.4 Cartographic Projections library originally
written by Gerald Evenden then of the USGS. The primary version of this
web page can be found at <a href="http://www.remotesensing.org/proj">
http://www.remotesensing.org/proj</a>.<p>
<!---------------------------------------------------------------------------->
<h2>Download</h2>
The current development source is available by anonymous CVS. It can
be checked out as the "proj" component. Review the
<a href="http://www.remotesensing.org/docs/howto-cvs.php3">OSRS CVS HOWTO</a>
if you need more information on using OSRS anonymous CVS.<p>
The following files are available from the
<a href="ftp://ftp.remotesensing.org/pub/proj">proj ftp directory</a>:<p>
<ul>
<li> <a href="ftp://ftp.remotesensing.org/pub/proj/from_kai/PROJ.4.3.3.tar.gz">PROJ.4.3.3.tar.gz</a>:

<h2>Plans</h2>
I (<a href="http://gdal.velocet.ca/~warmerda/">Frank Warmerdam</a> -
<a href="mailto:warmerda@home.com">warmerda@home.com</a>)
have been using PROJ.4 for a number
of projects of mine. PROJ.4 has been without maintenance for nearly five
years now since Gerald Evenden retired. I have been in contact with him, and
he has indicated no interest in actively maintaining PROJ.4.<p>
It is my intention for this version (here at remotesensing.org) to be the
new official version of PROJ.4. So far I have redone the makefiles and
configuration mechanism to use automake, autoconf and libtool. As well as
couple of portability fixes have been incorporated.<p>
It is my hope to involve the
<a href="http://hgeo02.geog.uni-hannover.de/grass/">GRASS</a>,
<a href="http://mapserver.gis.umn.edu/">MapServer</a>,
and <a href="http://132.156.30.81/iii/">OGDI</a>
communities all of which use some version of PROJ.4 though in some cases
with substantial changes. I am also using PROJ.4 in my own projects, including
using it as the basis of <a href="http://www.opengis.org/">OpenGIS</a> inspired
coordinate transform services.<p>
If you are a user of PROJ.4, and/or are interested in contributing please
drop me a line and join the mailing list. <p>
<!---------------------------------------------------------------------------->
<h2>License</h2>
I have tentatively placed PROJ.4 under an MIT license. I believe this to
be as close as possible to public domain while satisfying those who say that
a copyright notice is required in some countries. The COPYING file read as
follows:
<pre>
All source, data files and other contents of the PROJ.4 package are
available under the following terms. Note that the PROJ 4.3 and earlier
was "public domain" as is common with US government work, but apparently
this is not a well defined legal term in many countries. I am placing
everything under the following MIT style license because I believe it is
effectively the same as public domain, allowing anyone to use the code as
they wish, including making proprietary derivatives.
Though I have put my own name as copyright holder, I don't mean to imply
I did the work. Essentially all work was done by Gerald Evenden.
