Although we don't require you to have PostGIS 2.1 and PostgreSQL 9.3 to attend these tutorials, you'll be better able to follow along if you do.
We'll be posting downloadable data, tutorial materials and examples for these here so bookmark this page so you can cut and paste the examples if you want to follow along.
Since time is short, we have a lot of ground to cover, and there are various platforms people will be using, we won't have time to help with installation issues. However we will have the slides posted here and available after the presentations, so you can always try these exercises after the sessions.
If you'll be at either of these tutorials and have particular kinds of examples you'd really like us to demonstrate, email us at email@example.com.
We will also be using NodeJS as a quicky web app for viewing data. For the NodeJS, install NodeJS, make a directory where you'll host the app. Source code for quicky app is https://github.com/robe2/node_postgis_express
At OS shell/command line prompt. Run the below two.
npm install express
npm install pg.js
OSM2PGSQL is a command-line tool for loading OpenStreetMap data. We'll be using it to load Chicago OSM data. If you are a windows user, we suggest http://wiki.openstreetmap.org/wiki/Osm2pgsql#Cygwin which seems to be the most robust when working on windows.

We'll cover core PostGIS types geometry, geography, and the tiger geocoder packaged with PostGIS. We'll also explore a bit the 3D-geometry types.
Sept. 17, 2014 01:30 PM - 4:30 PM
This session assumes you have an understanding of PostGIS geometry. We'll cover some nifty things you can do with PostGIS raster and also explore PostGIS topology and pgRouting.
To get the most out of this you should have pgRouting installed as well.
For network routing, we'll build our pgrouting network using http://osm2po.de which is a Java-based loader for OSM (PBF, OSM,bz) formats and loads in a routable form. We'll be using our chicago pbf file. Already processed data is hh_2po_4pgr.sql.bz2 (40MB)
Stay tuned for our next book pgRouting: A Practical Guide published by Locate Press due out in hard-copy 4th quarter 2017. Content is now feature complete and can purchase e-Book draft and get final when goes to print.
