"Who you gonna call?"

"Geo busters!" (apologies Ghost Busters).

Geodata access and availability is the real story behind the flurry of news around UK government freeing up some data, vs. Google collecting it and returning it for free, and many others. And this happens against a backdrop of various SDI (spatial data infrastrucutre) intiatives. I joined a UK government data developers mailing list, to educate myself on the ins-and-outs of data provision at the coal face, so to speak. And RDFa emerges as the way to resolve this - the more metadata one provides within any given dataset, the easier it is to classify and maintain internally, and to discover and distribute externally.

Fun with Maps

I had planned a GIS Day project, but my schedule got way ahead of me, so here it is instead. I twittered a few spatially-related jokes to ask for some more, and I post here its beginnings on my website (click on the image). It combines a feed-back form to send suggestions, and a map to post the country, the joke if it's appropriate, and the author if given.

Digital ghost towns

Issues with Google's maps are aplenty, as Peter Batty, James Fee and others piped up amidst flurry of crowd-sourcing and free-sourcing etc. In quiet rural Northwest of England, however, Argleton appears to be an enigma - not only is that non-existant locality posted by some web streetmaps, but also searching can post images and businesses nearby - truly a digital ghost town! Having just compared various street maps in my home town, I did the same in the British postcode area: L39 5.

A tale of two systems

The last picture in my previous post was in fact a teaser - the basic premise is that with the right technical tools and business plan, an entire system can be assembled today for the cost of just the software of yesterday. So basically a sports car can be had today, for what it cost to just get the chassis a few years ago. How then, you might ask?
