GeoRabble Perth 12 – The Mix Bag Wrap

GeoRabble 12 was an eye-opening extravaganza of topics we’d all love to get involved in and many being accessible and happening right here in Perth.

Volunteering a weekend to join a similarly willing and dedicated team in problem solving and programming was a timely showcase from Zane Prickett and an invitation to join Unearthed. Now in its second year, Unearthed was held in Perth in late March and is being expanded to 4 events across Australia in 2015. The Unearthed hackathon was set up to promote start-up companies and entrepreneurial ideas in the mining sector solving technical problems with innovative new ideas.

Dr Ori Gudes showed some incredible (sometimes frightening) tales of health stories told through maps. His journey in mapping diseases, nutrition, health tracking and getting all the health facts onto maps to help inform patients, planners and health professionals alike.

Erik Champion talked about the incredible 3D theatre HIVE at Curtin University and the work he and his students are doing by creating fully-immersive digital version of places around the world from long-ago. Virtual reality, open source tools and data including LIDAR, 360° photography and a little archaeological knowledge are used to share history as it’s never been taught before.

This type of interactive game play and learning is now allowing us to take part and interact with historical ritual in original settings and gain a better understanding of our heritage.

Mathieu Savard, all the way from Canada, demonstrated the wonderful world of motion capture for gaming with a live demo with a motion sensor input device  hooked up to a PC! His presentation showed us what can be done with a 3D model created in freely available software; and just what an engrossing and new experience we can create.

In the final presentation Steve Weiser showed us some of the drivers behind the Just Start IT program and how their 18 week high school program across some 30 schools in Perth is helping to instil business, life and technology skills in high school students. Steve demonstrated why it is so vitally important that we help to make this a generation of kids the new job creators in markets we haven’t seen or realised yet.

AmbleMate is a web-based tool to help pick best walking/cycling paths in Australia but prototyping just on ACT. The tool can include most gentle walk or most challenging ride or pram/wheelchair accessible depending on personal preference. It works like Google Maps; just say where From and where To and it works out the optimum path.
The complete speaker line-up:
  1. Slava Barouline 6:15pm – 6:30pm
  2. Alex Sadlier 6:30pm-6:45pm
  3. James O’Brien: 6:45pm-7:00pm: “Social Landscape – A Case Study in Mobile GIS App Development”
  4. Discussion Forum – MC  (Geoplex)

The Boundary Mapper’s Cookbook

Dots on maps don’t always tell you the full story behind the numbers.  In cases where you’ve got postcode, suburb or council based data – you’ll want to be able to map those boundaries to tell a richer story than text, numbers or dots can do.

Here’s a quick and dirty guide to getting up and running with boundary data just in time for GovHack:

1 – Install PostgreSQL 9.1 : http://www.enterprisedb.com/products-services-training/pgdownload

2 – Install PostGIS 2.0 : http://www.postgis.org/download/  (there are now 64bit binaries for those who want serious spatial power)

3 – Download some Shapefile (SHP) formatted boundary data and load it into PostGIS (there’s a GUI – PostGIS Shapefile and DBF Loader 2.0 – inside the PostgreSQL Admin Console).  If you’ve got another format there are OS tools you can use – try OGR2OGR (handy guide here)

4 – Download some data to go with those lovely boundaries – e.g. some juicy hot off the press ATO Tax data

5 – Install PHP 5.3 on your web server with the PostgreSQL PDO drivers : http://php.net/downloads.php

6 – Download the PostGIS RESTful Web Service Framework 1.1 (PRWSF)

7 – Edit the PRWSF /inc/database.inc.php file to set your PostgreSQL database connection

8 – Download Leaflet Javascript API

9 – Get a Cloudmade account for a free API key to access to an OpenStreetMap tile layer of your choice

10 – Edit the PRWSF /v1/ws_geo_attributequery.php file to support callbacks for cross domain JSON:

     echo $_GET[‘jsoncallback’] . ‘(‘;


    echo ‘)’;

11 – Leech some code from GitHub

FYI – the ABS has a rich collection of boundaries for you to use under Creative Commons licensing.  This links directly to their own stats as well as the stats of many other agencies and organisation, such as the ATO (who recently released a tonne of tax data!).  This data is ripe for rich visualisation:


Note: 2006 Census data uses he ASGC boundaries.  2011 Census data will use the ASGS bdys when the data is released on June 21.

Here’s one I prepared earlier…
