<title>Introduction</title>
|
|
|
|
<para>PostGIS was developed by Refractions Research Inc, as a spatial
|
|
database technology research project. Refractions is a GIS and database
|
|
consulting company in Victoria, British Columbia, Canada, specializing in
|
|
data integration and custom software development. We plan on supporting and
|
|
developing PostGIS to support a range of important GIS functionality,
|
|
including full OpenGIS support, advanced topological constructs (coverages,
|
|
surfaces, networks), desktop user interface tools for viewing and editing
|
|
GIS data, and web-based access tools.</para>
|
|
|
|
|
|
<para>PostGIS is an incubation project of the OSGeo Foundation. PostGIS is being continually improved and funded by many FOSS4G Developers as well
|
|
as corporations all over the world that gain great benefit from its functionality and versatility.</para>

<para>
|
|
The PostGIS Project Steering Committee (PSC) coordinates the general direction,
|
|
release cycles, documentation, and outreach efforts for the PostGIS project. In addition
|
|
the PSC provides general user support, accepts and approves patches from the general PostGIS community
|
|
and votes on miscellaneous issues involving PostGIS such as developer commit access, new PSC members
|
|
or significant API changes.

<para>Crowd funding campaigns are campaigns we run to get badly wanted features funded that can service a large number of people. Each campaign is specifically focused on a particular feature or set of features. Each sponsor chips in a small fraction of the needed funding and with enough people/organizations contributing, we have the funds to pay for the work that will help many. If you have an idea for a feature you think many others would be willing to co-fund, please post to the <ulink url="http://postgis.net/mailman/listinfo/postgis-users">PostGIS newsgroup</ulink> your thoughts and together we can make it happen. </para>
|
|
<para>PostGIS 2.0.0 was the first release we tried this strategy. We used <ulink url="http://www.pledgebank.com">PledgeBank</ulink> and we got two successful campaigns out of it.</para>
|
|
<para><ulink url="http://www.pledgebank.com/postgistopology"><emphasis role="bold">postgistopology</emphasis></ulink> - 10 plus sponsors each contributed $250 USD to build toTopoGeometry function and beef up topology support in 2.0.0. It happened.</para>
|
|
<para><ulink url="http://www.pledgebank.com/postgis64windows"><emphasis role="bold">postgis64windows</emphasis></ulink> - 20 someodd sponsors each contributed $100 USD to pay for the work needed to work out PostGIS 64-bit issues on windows. It happened. We now have a 64-bit release for PostGIS 2.0.1 available on PostgreSQL stack builder.</para>
