GeoRabble Perth #17 – it’s a wrap!

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 perth@georabble.org.

Stay tuned via #georabbleper for news about our next event coming up soon.

 

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.

GeoRabble Perth #9 Review

Over the four long, hot months since the WALIS forum in November, Perth geo-geeks built up a Rabble-sized thirst, with only one way to quench it… cue GeoRabble Perth #9! Held at the Universal Bar in Northbridge, this iteration of Perth’s favourite geo-outing drew a big crowd, including some of the usual suspects and many new faces.

As usual, we had a great array of thought provoking speakers bringing their perspective on what makes our field of endeavour fascinating. It’s not easy to stand up in front of your peers and talk about yourself for 10 minutes, particularly given GeoRabble’s strict rules on sales pitches, ‘about us’ slides, etc… but these folks really delivered the goods.

Ably hosted by Chelsea Samuel, GR#9 was kicked off by Grahame Bowland, who dazzled us with some pretty serious SQL queries, but promised that his open source geodata analysis framework would save us from having to write them ourselves.

Emil Vulin was up next, and shared his perspective on the exciting area of mobile mapping, including some interesting observations on the arrival of low-cost tablets in the developing world.

Sophie Richards’ talk on her experiences in crisis mapping with the UN, and particularly the use of crowdsourced information, was a fascinating look into how mapping and spatial data can make a real impact in the lives of people.

For something completely different, Chris Toovey treated us with some eye candy, talking about his experiences in the business of making 3d animated scenes, as said scenes flashed by on the screen. Cool!

Finally, Dan Goldberg, visiting from the University of Texas, dropped in to tell a few jokes and talk up his students.

And with the presentation portion of the evening at its end, the GeoRabble settled in for beers & some spirited conversation.

Thanks to all our speakers for entertaining us and providing food for thought, and to everyone who came and made GeoRabble #9 a great night! We’ll look forward to seeing you at the next one, and if you have a geo-story to tell, we want to hear from you…  Also thanks to our sponsors Talis Consultants

Perth Georabble #8 Review

Around 170 people were a part of Perth’s biggest rabbling ever, with MC John Bryant leading the evening.  The event was held at Crown Burswood as a part of the WALIS Forum. Thanks to our sponsors SIBA (Spatial Industries Business Association) and WALIS Forum for having us there.

Brett Madsen was the first speaker, and it was a privilege to have a founding GeoRabble kick-starter from the East join us. His tale of where he has come from kept the audience captivated. Rules of GeoRabble may have almost been broken when services and business were hinted at –come on @DARKspatialLORD you should know better!

Darren and Brett

Perth’s own GeoRabble committee member Darren Mottolini took over the microphone to let us in on distorting maps and how to get a message communicated through map distortions. Ending with zombie maps, what was not to enjoy in Darren’s talk?

A further founding GeoRabble kick-starter, Maurits van der Vlugt travelled a long way just to join Perth GeoRabblers for the evening (well, we would like to think it was just for us!). He delved into the fascinating topic of gerrymandering, and the influence that electoral boundaries have on election outcomes.

Lise Summers gave us a fascinating look into how maps are carefully taken out of archives, off the printed and hand drawn pages and captured into formats able to come alive on our computer screens. Lise’s description of her experiences with the digital capture process was an eye opener, to say the least. The amount of work and care taken to not destroy these precious pages in the capture process was remarkable.

Ever built a computer chair out of a car seat and a massage chair so that you can fully experience the bumps in the road in a game? Well, Erik Champion was involved in doing so. Making computer games come alive and really getting to experience the simulation world made for a fantastic talk.

Helen Ensikat has created Beaufort Street Maps capturing Beaufort Street in a stunning way. Various aspects of this street have been captured from Helen’s view point. From the coffee shop where she drank great coffee, to the stars, the food ratings of the restaurants, tagging on the walls, to the little black poodle which has a fluffy tail have been captured for all to see.

Please come along to the final gathering for 2013. This month we’ll be joining forces with the Perth GeoSpatial Network to celebrate the end of year with some casual drinks at Bob’s Bar (http://www.printhall.com.au/bobs-bar/ ). We look forward to seeing you there 🙂
When: Wednesday, 4th Dec, 5:30pm
Where: Bob’s Bar (Rooftop bar of the Print Hall)

If we don’t see you there, we hope you have a great festive season and we’ll see you in the new year – for GeoRabble #9!

GeoRabble Perth #7 Event Wrap

GR7Perth_crowdWith a roll of the dice, the evening kicked off to an exciting start with speaker Kate Raynes-Goldie who brought the world of community game design to the GeoRabble stage. GeoRabblers got a glimpse into how location plays an important role in the construct of community games where play involves people gathering in locations or moving across them. Examples were given of “Gentrification” and Paparazzi; the latter of which was a GPS driven cat-and-mouse game of ambushes, paranoia and scandalous photos; drawing a link with the (perhaps) more familiar ‘game’ of geocaching. A “Community Games” workshop will be held at SpaceCubed in July, for those interested in learning about game design.

Next up on the GeoRabble mic was Erwin Vos, who delighted GeoRabble crowd with pretty pictures and anecdotes of jobs gone-past (including a stint as a sous-chef at the 2010 Vancouver Winter Olympics); with, of course, more onus on the pretty pictures! Passionate about imagery, Erwin describe the multitude of opportunities that exist for interpreting, analysing and using imagery; from detecting houses with poor insulation through to detecting land use change. The possibilities are limited only by the imagination (and knowledge of imagery components and techniques)!

The night’s mystery speaker was then (in dramatic drum rolling excitement) unveiled: Andy Waddington! Well, perhaps not in such dramatic fashion, but you get the idea. An experienced FIG/IHO Cat A Hydrographer (not sure what all those letters mean, but I’m sure they’re awe-inspiring!), Andy spoke about the charting of marine areas and sailed us through the methodologies carried out in the past (“There be dragons” was, once upon a time, a sufficient enough map indicator), those at present and those potentially used in the future. Andy also spoke about how charting now involves less dangerous voyages into areas to be charted (thanks to the power of spatial technologies such as lidar) but that in turn curtailing decisions had to made on aspects such how much area to survey or how much detail to capture. In the context of this, Andy stressed the importance of being able to know when to reuse data and gather as much information as possible from what was available.

Back on dry land, Liz Marjot was the next speaker of the night and spoke about a WA program called Spatial Technology in Schools (STIS). Liz described how the program came into being and the importance of spatial education for youth today. In particular, Liz spoke about how the interaction with spatial technology can spark interest and passion in geography and mapping, which oftentimes is lacking in a traditional classroom setting. Giving examples of some student projects, Liz described how powerful GIS can be in an applied setting in engaging students and encouraged us all to participate in bringing geospatial technology to the youth of today.

Leading on, Shane French spoke to GeoRabblers about the transition of a corporate GIS from a commercial software environment to an open source one; and gave an insightful and honest comparison of the similarities and differences, and the ups and downs encountered along the way (and did a great job of sticking to GeoRabble manifesto by not mentioning any product names!). It was a great overview for those pondering the change and implications it could have.

Last, but not, least GeoRabblers were treated to unique presentation by Hai Tran who spoke about drones and use of them to capture spatial data in a variety of contexts; from constructing aerial panoramic views of landmarks, to monitoring agricultural land, to capturing imagery to assist in the search for a missing Canadian bushwalker. Hai also spoke about the benefits of using drones: the low cost, the ease of deployment and processing; but also the diversity of use – how the drone’s payload can accommodate all sorts of devices for data capture. Though, for those enthusiasts out there, Hai did mention that being able to fly drones of this calibre did require a license (and permission from airport(s) to fly in certain areas).
