Crowd Funding Campaigns : 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 PostGIS newsgroup your thoughts and together we can make it happen.
PostGIS 2.0.0 was the first release we tried this strategy. We used [PledgeBank](http://www.pledgebank.com) and we got two successful campaigns out of it.
[**postgistopology**](http://www.pledgebank.com/postgistopology) - 10 plus sponsors each contributed $250 USD to build toTopoGeometry function and beef up topology support in 2.0.0. It happened.
[**postgis64windows**](http://www.pledgebank.com/postgis64windows) - 20 someodd sponsors each contributed $100 USD to pay for the work needed to work out PostGIS 64-bit issues on windows. It happened.
Important Support Libraries : The GEOS geometry operations library
The [GDAL](https://gdal.org) Geospatial Data Abstraction Library used to power much of the raster functionality introduced in PostGIS 2. In kind, improvements needed in GDAL to support PostGIS are contributed back to the GDAL project.
The [PROJ](https://www.proj4.org) cartographic projection library
Last but not least, [PostgreSQL](http://www.postgresql.org), the giant that PostGIS stands on. Much of the speed and flexibility of PostGIS would not be possible without the extensibility, great query planner, GIST index, and plethora of SQL features provided by PostgreSQL.
