Local Video for Local People

OK it’s all Google stuff, but still good to see. Go to Google Maps, My Maps, to find ‘Videos from YouTube’ listed. Here’s where I used to live (Bristol UK) and where I live now (Amsterdam, The Netherlands). Here’s a promo film of some nearby art installations from ArtZuid, who even have a page in [...]

Fireeagle IRC bot / OAuth / Dopplr

I noticed people in #geo playing with a fireeagle bot earlier, so I had to try too.
danbri: fireup, help?

AllegroGraph RDFStore 3.0: Social Network Analysis

AllegroGraph 3.0 now comes with a Social Network Analysis component, amongst several other interesting features including improved geo support.

By viewing interactions as connections a in graph, we can treat a multitude of different situations using the tools of Social Network Analysis (SNA). SNA lets us answer questions like:

How closely connected are any two individuals?
What are [...]

Geographic Queries on Google App Engine

Much cleverness:
In this way, I was able to put together a geographic bounding box query, on top of Google App Engine, using a Geohash-like algorithm as a storage format, and use that query to power a FeatureServer Demo App Engine application, doing geographic queries of non-point features on top of App Engine/BigTable. Simply create a [...]

Open CellID databases

Via momolondon list: opencellid.org data dumps
The readme.txt file describes the tabular data structure (split into a cells, and a measures file).
I think the cells data is the one most folk will be interested in re-using. Table headings are:

# id,lat,lon,mcc,mnc,lac,cellid,range,nbSamples,created_at,updated_at
For example:
7,44.8802,-0.526878,208,10,18122,32951790,0,2,2008-03-31 15:22:22,2008-04-07 08:57:33

This could be RDFized using something similar to the (802.11-centric) Wireless Ontology. Perhaps even [...]

Google Earth touring via KML

While I’m writing up old hacks, here’s one that I really enjoyed, even if it was a bit clunky. A couple of years ago Mikel Maron implemented (on my urging in irc.oftc.net #geo IRC :) a PHP-based Google Earth touring service, which interconnects a “tour guide” user with “tourists”.
This site facilitates collaborative, realtime exploration [...]

Bottles and teargas in Piazza Navona

I’ve just posted 100 or so photos from the anti-Bush protest in Rome last night. Zac and I were on the way to a restaurant when we stumbled into the protest in Piazza Navona, just by the Senate where Bush apparently was in meetings. We wandered around the square taking photos of the protesters, then [...]

In our daily lives we all respond urgently to dangers that are much less likely than climate change to affect the future of our children. … Feb. 2 will be remembered as the date when uncertainty was removed as to whether humans had anything to do with climate change [...]

Who, what, where, when?

A “Who? what? where? when?” of the Semantic Web is taking shape nicely.
Danny Ayers shows some work with FOAF and the hCard microformat, picking up a theme first explored by Dan Connolly back in 2000: inter-conversion between RDF and HTML person descriptions. Danny generates hCards [...]
