Proudly sponsored by: Geoplex
Where: Digress Restaurant in Akuna Street, Canberra City..
When: 16th August 2012, 6pm
Cost: Free (drinks are available for purchase from the Digress Lounge Bar)
Places are limited so book now!!
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)

First Speakers Announced for GeoRabble Sydney #5

Leave a comment

We have some great talks lined up for our next Sydney GeoRabble, on Thursday 23 August.

Sponsored by EBR

In a GeoRabble first, Tim Leigh will let the audience choose the topic for his talk. Democracy at its best! Choose anything from Web GIS to Mobile App development or Dog Sledding, and Tim will improvise!

Other Rabblers include:

  • Andrew Harvey – “Open StreetMap, My Story”. Andrew’s short but sweet narrative about his experience with OSM, why he’s contributed, what he’s learnt from it and what he gained from it.
  • Mark Greenway and Kelvin Nicholson – “Happy Mapping”. How their GovHack team created a map of ‘Gross National Happiness’ combining mapping and statistical skills.
  • Stephen Lead – “Mapping the Anzac Diaries”. How the State Library of NSW displays diaries written in the trenches of WW1 in a modern and enticing manner, including placing the diary entries on a map.

There are still speaking slots open. Have something interesting, passionate of fun to share? let us know by emailing sydney@georabble.org.

For this GeoRabble, we are bringing back the free Pizza (thanks to EBR), so don’t miss out! Spaces are limited. Join our Meet-up group, or register here!

GeoRabble Perth #3

GeoRabble #3 Perth, 25 July, Belgian Beer Cafe

A very successful event attended by 80 people, of which half had not attended before.  Several of the usual faces commented that they did not know quite a few people, so perhaps GeoRabble is succeeding in reaching out beyond the spatial nucleus.  Tom Brownlie was the Master of Ceremony and reminded people of the rules of GeoRabble – including to celebrate all things spatial.  Bringing the rabble together to quiet down and listen to the two speakers was easier than thought with the amount of chattering.  David Brady gave us a interesting talk about fact and fiction using maps as the examples.  Apparently there are lies/inconsistencies within the Asterix maps!

Our expert panel of Phil Beach, Chelsea Samuel, Sonny Tham, Bernard O’Sullivan and Richard Brown have not been allowed in the same room together in the hopes of some rabble fireworks.

GeoRabble Perth #3 Announced!

Leave a comment
Having had a strong showing at the last Perth Georabble, the middle of the year calls another night out for GeoBeer, GeoTalks, GeoDiscussion and GeoRabble.
With a good shortlist of speakers, and a discussion panel on the use of data warming up in the wings, the venue organised, now is the time to get your tickets.

GeoRabble Perth #3

Wednesday July 25
Doors open 5.30pm, talks from 6.15pm
Trappist on King
Cnr King & Murray Sts Perth
Perth, Western Australia 6000
This time in a very special GeoRabble first, we’re going to use half the night in an open panel discussion.  What are we talking about? The amount of effort versus return?  Poor quality data in, can only result in bad decisions?  Or can we create silk purses from hogs ears? Perfection in information is a matter of definition as rubbish data can still be perfect for specific situations, depending how it is used and what it is used for.
Help us and the panel put fact before fiction – perhaps!

The Boundary Mapper’s Cookbook

2 Comments

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’] . ‘(‘;

                require_once(“../inc/format.inc.php”);

    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:

http://www.abs.gov.au/websitedbs/D3310114.nsf/home/ABS+Geography+Publications#Anchor8

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