Some great questions have been answered in a recent blog post from the OpenGeo crew. The meaty article takes a close look at the OpenGeo Suite as well as a look at the individual, OpenGeo Components. For the non-developer type like yours truly, this is an excellent and must read if you think there’s any chance you might be considering a move to open source solutions in your mapping workflows.
From the article… all of the components of the OpenGeo suite are open-source software projects with a community of developers behind them.
- PostGIS – a spatial database extender for the PostgreSQL object-relational database. It adds support for geographic objects allowing location queries to be run in SQL (http://postgis.net/). TIP – see this video
- GeoServer – GeoServer is an open source server for sharing geospatial data (http://geoserver.org/).
- GeoWebCache – a Java web application used to cache map tiles coming from a variety of sources such as OGC Web Map Service (http://geowebcache.org/).
- QGIS – a free and open source desktop Geographic Information System (http://www2.qgis.org/en/site/) TIP – see this how to video
- OpenLayers – A high-performance, feature-packed library for all your web mapping needs (http://openlayers.org/)
While the specific open-source license for each varies slightly, they are all considered Free and Open Source Software (FOSS) applications without any license fees or royalties.
