Urbanscale – Spime Wrangler

Google StreetView was certainly a trail-blazing concept and it has entered the mainstream. But it was not the first service and Google isn’t the first company that had the concept to collect data about the physical world by driving a specially equipped vehicle (with one or more cameras, high performance GPS and other sensors) through space. Decades earlier, the Jet Propulsion Laboratory worked on this concept in order to permit the vehicles landing on the moon (or other spatial bodies) to record their immediate environment. Earthmine is a pioneer not only in the capture of the real world (using designs developed by the JPL) but also to explore business models based on this data sets. What do these have in common? They proved that the ambitious goal of digitally “capturing” the real world in a form that supports navigation through the data afterwards, was possible.

As the technologies developed in these projects have evolved and become more powerful–in every dimension–and competitors have emerged based on other maturing technologies, systems are detecting the physical world at higher and higher resolutions, and the data gathered produce increasingly more accurate models at lower costs.

Instead of “manually” building up a 3D model from a 2D map and/or analog data, urban environments are being scanned, measured and modeled at an amazing speed, and at lower cost than ever before. Fascinating, but to what end?

In the AR-4-Basel project, we seek to make available to AR developers accurate 3D models in order for the digital representation of the real world to serve as the basis for higher performance AR experiences. The concept is that if a developer were able to use the model when designing experiences, or the placement of content, they would have a virtual reality in which to experiment. Then, when in the real world the user’s device with a camera would automatically extract features, such as edges of buildings, roofs, and other stationary attributes of the world, and match those with the features “seen” earlier in the digital model. The digital data would be aligned more accurately and the process of augmenting the world with the desired content would be faster.

In order to determine if this is more than just a concept, I need to find and receive the assistance of 3D city model experts. Here are a few of the sites to which I’ve been in search of such knowledge:

CityGML web site and articles such as this one by Thomas Kolbe in 2005
3D Reality Maps
CyberCity3D
Procedural
SemCity
Navteq Network for Developers
GeoSim Cities
Video and Image Processing Lab on 3D City Models (UC Berkeley)

This process is proving to be time consuming but it might yield some results before another solution to improve AR experience quality emerges!

Smart Cities and Big Citizens

The AR-4-Basel project is a framework by which public data about a city, the city of Basel more specifically, can be put in the hands of Augmented Reality developers using a variety of tools and platforms and to encourage the development community to be creative. Many scenarios for AR in urban environments are for consumers. The end goal being that if we knew more about our immediate environments, we might make different decisions.

The departments of the city of Basel with whom I'm in communications are primarily thinking of the Internet of Things, and AR in particular, as a professional tool, enabling people to do their job more efficiently when in the field, perhaps to save on resources/reduce waste (increase efficiency) and to make better decisions which might impact their lives or those of others.

So, in the context of this project, I'm spending a lot of time speaking with experts and reading the opinions of those much more informed in these matters of "smart cities" than I. Martijn de Waal is one of those that has invested highly of himself in this topic and clearly "gets it."

One of the posts that I found particularly enlightening is a "dialog" of sorts between Ed Borden of Pachube and Adam Greenfield of Urbanscale. Rather than read my paraphrasing, please read it.

At this point, the jury is out on if these are really different positions and if different, which of these positions best characterizes the situation. It is early enough that cities (BigGov) and their managers (politicians) could "wake up" and take a more active role in their own technology use. But not all citizens want or should be participating in the decisions that require having all (and some of it sensitive) data. And, it is definitely true that citizens can and should be involved in some of these services which primarily benefit them.

I look forward to seeing this dialog continue and to learning more from the experts in this field. Maybe as a small citizen of a small urban area in a small country, I will be able to make a difference in how others live.
