Today some 230,000 miles of Street View coverage has gone live in Google Maps, which represents arguably the most detailed map of the UK every produced. I say this because of the amount of information contained in each panoramic photograph is simply massive.

Yes it may not look like a conventional cartographic map, but it is nevertheless rich geospatial information and represents the next evolution of maps.

Street View images contain both quantitative information, parking restrictions from signs, opening times of shops, the type of tree most common is the surburan streets of Manchester and qualitative information, the “sense of place” something  very difficult to represent using traditional cartographic techniques.

Street View imagery in the UK will I hope become a valuable resource to academics researching the state of the nation at the beginning of the 2010’s, a image taken every 10 metres or so for 238,000 miles a distance equivalent to travelling from the earth to the moon, must represent one of the largest archives of photographs ever collected.

It is disappointing that the raw images used to create street view will have to be destroyed at the request of the European Union Data Protection Working Party, leaving only the privacy blurred published versions for future generations to accesses, still that is the balance we need to achieve between providing useful services and protecting privacy.

When I was running around Covent Garden in the early 1990’s creating a “hypermedia” map using a video camera and Apple’s Hypercard, I had a vague idea that such a database of navigable scenes might be extended to other parts of London, but National Coverage… that would have been Science Fiction !

But then again so once was putting a man on the moon !

It is always a nice opportunity to speak to people who are not GI Industry experts or mapping mavens but who are “normal” people whose lives are however impacted by Geospatial Technology.

On Monday I has the massive pleasure of meeting some of the business owners located on Shambles which was a winner in one of this years Street View Awards.

Shambles is not your usual shopping street, it looks like a set from the latest Harry Potter film and is populated by various specialist shops including Past Images whose owner Ian I got talking to.

Now you too to can explore this special part of York here virtually , but if you get the chance visit York, make sure you visit yourself !

Ian and his fellow shopkeepers are all enthusiastic users of the web, have websites and appreciate how much difference tools like web search and online mapping have made to their business. Rather than driving trade away, the web is making it easier for potential customers to find their businesses.

Finding is the key point here, I think we in the GI industry often forget just how powerful a simple map showing the location of a business really is.  While we talk about the virtues of Foursquare vs Gowalla or debate how to represent disputed boundaries, real people are using the easy access to mapping to improve, in little ways, their lives !

Many European governments (and citizens) have expressed concerns about the privacy implications associated with Google's Street View - the street level images taken from cameras mounted on cars. Most recently, the European Union (EU) advised Google that it should warn towns and cities before beginning to collect images from its Street View vehicles. The EU, according to press reports, also suggested that Google should keep original photos online for only six months instead of a year. (Ironically, this could result in Google having to reshoot Europe every six months, which should raise even more privacy concerns.) This request was made even though Google is taking images from public places and already posts the itinerary for its vehicles on-line and blurs faces and license plates and will remove an image upon request.

The EU increasingly appears to be coming down on the side of individual privacy at the expense of Street View technology. As a result, Google may decide it no longer makes sense to offer Street View in Europe. However, one might question if the EU fully appreciates the value of the Street View data or has truly weighed the opportunity cost associated with losing this service in Europe.

Street View is more than a series of random images of a city or town. It is an organized collection of important information about a location at a given point in time at no cost to the government and available to its citizens for free. This information has tremendous potential value for future as well as current use. For example, imagine how valuable Street View would have been after the recent earthquakes in Haiti or Chile. Rescue workers would have been able to identify where to search with much greater precision and the images would have provided valuable information for reconstruction efforts. Unfortunately, European cities are at risk from similar natural disasters. Or imagine what today's historians could do if they had access to similar imagery of ancient Greece.

Protecting individual privacy is difficult, as the concept itself generally has both a legal and a cultural component. It becomes even more of a challenge when new technology is introduced, and often results in a cost/benefit analysis. However, any such analysis must be thorough and well informed. Restricting the use of new technology without such a rigorous analysis may ultimately prove to be short-sighted.

There has already been a good deal reported about the recent Congressional hearings regarding the privacy implications associated with the collection and use of location data on mobile devices. It should not be any surprise that Congress is taking a look at this issue, given the growing number of devices and associated consumer applications as well as the potential implications associated with this technology. Nor should it be surprising to hear Representative Rick Boucher state that future legislation will likely include provisions addressing this issue, as Congress been down this road before, including proposed legislation from then Senator John Edwards. In fact, it would probably be prudent for all companies in the U.S. that collect or use customer location data to become familiar with the privacy regimes associated with medical records (HIPAA), consumer credit (Fair Credit Reporting Act) and financial information (Graham -Leach- Bliley Act), as Congress and the Federal Trade Commission appear to have a framework they like to use on privacy matters. It is very likely they will try to apply a similar framework for location data.

Via the James Fee GIS Blog, the online mapping service Platial is shutting down. If you’ve been using it, you have a very limited amount of time to export it in KMZ format; access may shut down as early as March 2nd.  Geocommons will be acquiring the data from the past five years, and making [...] Related posts:

I spent the beginning of a very busy week last week talking about the benefits of making public sector data more accessible. I was speaking at the launch of public transit data in Brussels, where the local public transport agency STIB made their schedule information available for use within Google Maps in Belgium.

As in all previous Transit data launches this is a non-exclusive arrangement, and others organisations or individuals could make use of the data to build applications.. This is one of main drivers of making information like this available, as it allows innovative solutions to be developed rapidly to meet real user needs.

The most well developed ecosystem of applications developers around transit data has developed around the BART System in San Francisco, who have a web page listing around 30 free and paid for applications which help people use public transport in the Bay Area.

At last weeks launch in Brussels, a local developer eMich demonstrated their android application which provides access to real time information on the STIB system, clear evidence that Europe’s developer community are just a proficient  at meeting users needs given access to the data.

In the UK the government has made some excellent progress in both providing the mechanism to download government data sets, but also working hard to develop a community of developers and innovators around www.data.gov.uk.

Now just a few weeks after the site went live we are beginning to see applications developed that exploit the data, a personal favourite of mine is the asborometer, a mobile application that allows a user to understand local crime data in a very simple way..

Listen to the developer Jeff Gilfelt describe his project..
