We’re excited to kick off 2017 with a brand new spectacular GeoRabble!
Join us in the ‘rabblin fray to ponder, muse & debate all things spatial (and maybe even meander into the not-so-spatial!). Leading us to the fringes of the spatial spectacular, we are excited to announce the following line-up of titillating talks:
- Dhan Prabu – Maps with a Twist
- Suzanne Brown – Drainage and Liveable Communities
- More to be announced soon!
Date: Wednesday 22nd February 2017
Time: Doors open 5:30pm, Presentations from 6:00 pm
Location: Universal Bar, 221 William St, Northbridge
Format: A handful speakers, 10 minutes each, a room full of ‘rabblers, and the usual rules
Registration: Attendance is free, but for catering purposes we need you to register!
We can’t hold these events without the help of the greater Geocommunity! Please contact us if you’d like to be a part of sponsoring a future event or get involved in helping organise an event.
Starting us off for the night was Tracy Jin Cui, with a fast-moving slide deck (47 slides!) on spatial in China; and one thing was astonishingly clear -not only is the spatial industry growing – it’s booming; and is now worth about 42 billion (US) dollars. Demand for location products and services continues to grow at a fast pace, and predominantly the platform of demand/use is mobile.
Bringing us back to more local extents, Marcia Schneider walked us through the ‘Historical Panoramas: Perth and Fremantle’ project which was borne out of a collaboration between Curtin University’s HIVE and the State Library of Western Australia. The project sourced historical images dating as far back as 1860, and stitched these into seamless panoramas. A sample set was then selected and georeferenced; and a task then set to capture modern-day panoramas of the same locations. Challenges faced included trying to access locations that were no longer accessible (but luckily drone technology was on hand). The resulting product was a beautiful virtual tour of the selected locations with the ability to fade/time-slide the panoramas. The tour can be accessed online here; and more locations are in the pipeline.
Next up, we had Voon Li Chung speaking to the keen georabblers about a possible method to optimise database queries involving GPS coordinates. The kernel of the issue is when performing a proximity search for coordinates stored as part of a larger database/dataset, there generally is no spatial relationship or index component to speed up the search. Either you go row-by-row or store all coordinates in memory…. Not particularly desirable when your computational device is a smartphone (and a cheap one at that). The aim was to devise a solution that could use the at-hand, off-the-shelf smartphone database technology (sqlite3), which already had desirable features – it’s fast, simple and taps into inherent database qualities – such as integer searches. The solution proposed would allow one to set a point of reference (of a certain distance from an interest point) and pre-calculate distances of other points from this reference point; and then perform search for those points falling within a certain (pre-calculated) distance range. This concept was further refined upon by introducing bearing values between a point and the reference point. These combined heuristics reduced a sample search set of coordinates from 133354 points to just 98 points! Impressive stuff!
Carrying on from Voon Li, we had Onno Benschop talking to us about his experiences participating in this year’s GovHack; and he walked us through his team’s hack on public housing in WA. They attempted to answer the ‘flipside’ of the more commonly known/asked question of ‘where should we not build public housing’ in order to address the ‘where should we build public housing?’ question. To do this, they tried to ascertain housing demand and accessibility to key services (in areas such as health & education) in order to rank areas by their desirability for public housing; and then produced visualisation of this in a geographical format – a map. Onno also spoke to us about experiences in the hackerspace environment and what it’s like to be a part of such an event. The link to their project page is here.
To conclude the evening, we had John Bryant speaking to us about a wonderful local initiative called ‘GeoGeeks’ which is an open-source based geospatial hack group that brings together an inspiring bunch of people fortnightly to tackle geospatial projects. John talked us through a couple of projects on the go: the ‘Maps for Lost Towns’, a venture aiming to bring 6000 historical map images to keen georeferencers through crowdsourcing technology; and the ‘WA Media Statements’ project which seeks to geocode all existing media statements to enable location-based searching/viewing. And many more projects are on the books – such as spatially tracking food trucks through tweets, or solar panel crowdsourcing. John also touched on the reasons to become involved as geospatial professional, regardless of your level of experience. You can learn new geo skills and improve problem solving abilities; it’s also an opportunity to give yourself the time/space to actually work on your own ideas, network and build meaningful connections with other industry professionals. And, because people from all industry-walks of life are welcome, you might even have the opportunity to open your mind to new ways of tackling age-old geospatial problems. To find out more, head this way.
A huge thanks also to our sponsor – Survey Results. Cheers! We couldn’t run events like this without the generous support of organisations in our industry.
We’re also making a call-out for some new organisers to join the local Georabble team. If you have ideas for topics, even if that means dobbing someone else in, or can help us with some drinks and nibbles for next time, we’d love to hear from you via email@example.com.
Stay tuned via #georabbleper for news about our next event coming up soon.
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.
Georabble 13 promises even more for hungry Perth audiences with tickets for the June event becoming available soon.
GeoRabble #10 – It’s a wrap!
Happy 10th Birthday to GeoRabble Perth!
The evening kicked off with mirth to the sounds of a downpour or two as wet GeoRabblers braved the weather and trundled into the warmth and a welcome drink to celebrate all that is geo goodness.
Happy Birthday to Us, Perth is now 10 georabble’s old. For our 10th Rabble, we want a rabble of epic proportions!
