At FOSS4G we gave two presentations. The videos from other presentations are FOSS4G 2014 album. I have to commend the organizers for gathering such a rich collection of videos. Most of the videos turned out very well and are also downloadable in MP4 in various resolutions. It really was a treat being able to watch all I missed. I think there are still some videos that will be uploaded soon. As mentioned lots of PostGIS/PostgreSQL talks (or at least people using PostGIS/PostgreSQL in GIS).
Mending Spatial Data with PostGIS: Sorry no slides. Leo doesn't believe in slides and only believes in live presentations. But he has codeVideo .
Tutorial Sessions we gave at PG Open 2014
We have a biggish splash page for this with the related content. PG Open 2014.
PostGIS: Up and Running slides very incomplete but all I could get Leo to put up with and even had to sneak some in. The slides again don't cover all that was covered because Leo doesn't like slides and thinks all talks should involve running code live. So again please look at the code and use your imagination to figure out what transpired. I must add that SANS slides, Leo managed to cut into lunchtime I think I'm about to cut into your lunch time, everyone okay with that? Hold on let me check to make sure there is food left. At lease he recognized an issue. Thanks all for being a good sport about it.
PostGIS2.1 on Caffeine:Raster, Topology, and pgRoutingPDF version despite having 110 slides, I was a bit unprepared and had an embarassing amount of time left. Lesson learned follow Leo's lead with more live demos and polish up on my pgRouting and Topology content. If PG Open folks are willing to have us again, I should have a more polished training next time around. There was so much more about raster I wanted to say but didn't want to monopolize too much of the time talking about rasters.
