Finding a Good Data Source For a World Map. Last year I contributed a Flash-based world map to the open source Piwik Web Analytics project.
At that time, all of the Piwik charts where rendered in Flash, but as with release 1.5, all Flash charts were replaced with JS/canvas charts. Now, my map plugin is the only Flash component in the whole project, which is why they asked me if I could rewrite it in SVG. I will take some time in October to do this and I want to write here about my work. In contrast to many past projects where I wrote making-of like posts after finishing, I now want to write while working – literally. Spatial Networks Data Available for Download from WeoGeo Market.

It brings UN statistical databases within easy reach of users through a single entry point. WMO data provide the basis for better understanding the climatology of severe weather and extreme events such as tropical cyclones, El Niño, floods, heat waves, cold waves, droughts and other natural hazards, contributing to saving both lives and property, and improving our understanding and monitoring of the climate system and environment. WMO has drawn attention to issues of major concern, such as ozone layer depletion, global warming, climate change and diminishing water resources. WMO enhances the application of meteorological and hydrological information for the security and well-being of society.

There's a wealth of data out there... Bad things happen when problems are protected by a forcefield of tediousness. Here is an example. Data is the fabric of the modern world: just like we walk down pavements, so we trace routes through data, and build knowledge and products out of it. The government has lots of data that has already been collected, because it has needed it to run the country properly: simple stuff like maps, postcode areas, land ownership, procurement data, endless weather readings, and so on. Right now a fight is happening in Whitehall, with two factions in government: one group thinks we should give this data away for free, as a matter of principle, because it will make good things happen; the other thinks we should restrict access, and sell it. A consultation is under way. As things stand, much everyday government data is locked down so hard that nerds are forbidden to repurpose it. There are areas where access is won by the shame of a simple moral argument.
