Andrew's Talk at Web 2.0 Expo: Trends and Technology in Where 2.0

Our own Andrew Turner and Mikel Maron presented at Web 2.0 Expo today on trends and technology in Where 2.0.

Cutting Edge Where 2.0 Trends

To kick things off Brady Forrest of O’Reilly and Andrew just published a report on the GeoWeb space, it’s available now.

For those not familiar with the Geo-geek world they started off defining the Geoweb as an interlinked set of people and places around the world that is finally web aligned. These people and places are linked together through open standards that can be searched and indexed online. This gives us a huge trove of information and data from numerous sources.

A new driver of geodata is the trend towards mass adoption of location aware mobile devices. Users are bringing mobile devices into social environments, business, and even global settings. Socialight provides users collaboration capabilities leveraging online and mobile technologies to provide reviews and information on top restaurants and other locations. Large established companies such as TeleAtlas and NAVTEQ are actively expanding into mobile as well. Users can also gather data on their own, with massive success of OpenStreetMap being one prominent example.

The majority web 2.0 services are starting to add geography. Wikipedia, Flickr, even YouTube. This information can now be mined. Check out geocodr which create geotags based on Flickr photos.

One issue that’s coming up with all this open data is metadata and providing source authentication. Can the data be trusted? The ability to crowdsource information for a specific crowd or business is exciting, but having authoritatively knowing the source of where the information is coming from is even more important. Privacy is another pressing issue with open data. Flickr is offering geo-privacy to their photo uploads – this introduces the idea of “casual privacy”. Trusted locations also have a strong impact on how data is perceived by users.

Omnifocus has an iPhone tool that adds geolocation to your “to-do” list. It automatically geo-locates you, so you can discover the closest option to complete the next task on your list. So, if you’re out at CVS and need to go pick up something at a grocery store, Omnifocus can tell you where the closest store is to check that task off your list.

Mapvertising is another interesting concept. Coupons and other location based advertising have to be able to understand what users are searching for in context. For example, searching for a “romantic restaurant” should NOT result in an advertisement for Hooters.

Andrew also discussed advances in traditional GIS. ESRI is one big GIS solution provider that is opening their data via KML, javascript and flash.

Many new users are looking to do more complex analysis than just mapping push pins and would like to map more sophisticated open source and private data. For example, with Maker! you can take a look at how average rent in Manhattan can be thematically mapped to discover price trends.

Burning Man 2008 GeoHacks Technology (The future)

At this point Andrew passed the presentation over the Mikel to provide more of a geo-hacking perspective perspective on the GeoWeb. He got things into gear by discussing what he learned in the Black rock Desert of Nevada. Burning Man is a blank canvas on which to dream and create anything. It’s a single week long social experiment and a petri dish of urban development. It’s almost a laboratory that we can use to begin to examine all the geodata and tools we have. We can look at urban development, how social groups form in cities, etc.

Burning Man Earth had a lot of “geogeekery”. Over 100 GB of data were collected over the week.

Why is this important for Web 2.0 Expo? This is a prime example of Web 2.0 and Where 2.0 and what these technologies can enable. Open platforms, open standards, open data, and collaboration that is easy and cheap.

Amateur Remote Sensing

We took remote sensing data every day. You don’t need expensive gear or a satellite. Small planes are used to get imagery with under $500. A plane is used with continuous shots and a camera hanging out the window with a clamp. The pilot has to manage the camera out the window, but there were no problems finding volunteers. “There are 3 F’s that no pilot will refuse….Food, Fuel, and something else…” Not only did we get aerial pics from planes, but also from kites.

Some great shots were taken as burning man convened. You can see how people created their spaces based on where the ones before them placed their tents.

We then processed the photo using ERMapper, ESRI, Photoshop, and some blood, sweat and tears.

The GeoDjango platform was used to collect even more visual data. If you have geographic items in your models, it can map to nicer views. A camp layout was placed in CAD for even more visualization, which we received in a PDF. To georectify, we used ESRI. We also had to use WMS and tiling (TileCache). These OpenLayers provided vectors from the PDF.

We then wanted to extend this to a social networking platform and get media artifacts from the information. We used “pinax” for networking. This data can be used for future city layout and camp planning tools.

Flickr took these tiles so people could geotag their photos from Burning Man based on the location of their maps.

Some of the other technologies that were used during burning man was Garmin radio for friend location, GPS tracking of vehicles, digipeater (which rebroadcasts to the Internet down the line for free).

Parting words:

“The Internet brings us together, but what if the single link holding us in place breaks?
What if what we learn in the harsh environment of the playa could be reapplied to those in crisis, instead of artistic indulgence?”
