UK GIS Data Practices Hit the Fan

Guardian | Technology | Give us back our crown jewels

A detailed and pointed article in the Guardian (big UK paper) is making a big stink over the way UK tightly controls access to what the US classifies as "public" GIS data (ie. everyone pays big for publicly funded data). The paper is launching a campaign call "Free Our Data", against the current policies.

The article is definately worth a read for US GIS folk as it cites US data practices as a major foundation for all the arguments against the UK policies. If you want a case study in GIS data practices, this is a good place to start.
Pira pointed out that the US's approach brings enormous economic benefits. The US and EU are comparable in size and population; but while the EU spent €9.5bn (£6.51bn) on gathering public sector data, and collected €68bn selling and licensing it, the US spent €19bn - twice as much - and realised €750bn - over 10 times more. Weiss pointed out: "Governments realise two kinds of financial gain when they drop charges: higher indirect tax revenue from higher sales of the products that incorporate the ... information; and higher income tax revenue and lower social welfare payments from net gains in employment."

MapQuest Releases API

MapQuest: Features

MapQuest has released an API (MapQuest OpenAPI) so you can create your own maps using MapQuest maps.
The MapQuest OpenAPI is a free service that allows you to use JavaScript to easily integrate routing, geocoding and mapping into your website. With this feature-rich API you can create dynamic routing and mapping applications for personal or community use.

(Thanks Google for forcing MapQuest to be competitive and release their own API. Competition is a good thing.)

Better than Quicksort

Critticall home page

A site claims to have invented a better mousetrap - a sort algorithm that is faster than Quicksort. It is optimized for arrays that are somewhat structured with unique records.

In any case, it is a fun little read and something to try out.
