The STs of PostGIS
Tõnis Kärdi
PostGIS is a very powerful tool in the hands of anyone dealing with spatial data on a daily basis. We're going to look at some more or less useless but fun ways how PostGIS-flavoured spatial SQL can be used to dismantle, re-arrange, or even produce data. This talk will cover a few oddities I've been lucky to engage myself with over the past years. Expect gifs, and a lot of SQL.
