[OSGeo-Discuss] projects overview?

[Lee Breisacher]

Hi. I'm new to OSGeo and geospatial software in general (but certainly 
not new to software development). I would like to know if there is a 
single overview somewhere that summarizes and "ties together" the 
various OSGeo projects. I have visited the sites of each of the projects 
listed on the OSGeo home page, but I have not found anything that shows 
how the various projects are related, what data structures they might 
have in common, what overlaps there might be in functionality, what 
overlaps there might be in developers, etc.

I'm a developer and would like to become involved, but I'm not sure 
where to start. An overview would be quite helpful.

Thanks,

Lee
