The OSGeo have a brand new website design!
Check out https://www.osgeo.org/
The Open Source Geospatial Foundation supports all things open related to geospatial – both software and data. Check out some of the projects listed under the tab at the top of the homepage. There are OSGeo project as well as community projects. Some you’ll be familiar with and some will be new to you I’m sure – all of them are great in their own way.
On the website there is a list of ways to get involved with the OSGeo community and all sorts of information about different resources to further educate yourself and others. Take a moment to poke around the website – you won’t regret it!
