This month Steve Gifford ( from MouseBird Consulting will be presenting his talk "Geospatial Data Displays Using OpenGL". This talk will cover the basic concepts of OpenGL ES 2.0 and how it is used to create 3D shapes like a globe. It will also cover a few data organization algorithms for static data and then check out a couple of approaches for dynamic data.

Steve is the owner of mousebird consulting, makers of WhirlyGlobe-Maply (, an open source (as in free) toolkit for high performance geospatial data display on iOS. The WhirlyGlobe part is a 3D spinning globe and the Maply part is a 2D interactive map. Steve is a full time consultant, working for clients who actually need this sort of thing.
