Global level A new file with the (2011) global country boundaries. There's a wealth of data out there... Bad things happen when problems are protected by a forcefield of tediousness.

There's a wealth of data out there...

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. Online and Downloadable Data.

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.

Cartographic Boundary Files

The cartographic boundary files are simplified representations of selected geographic areas from the Census Bureau’s MAF/TIGER geographic database. These boundary files are specifically designed for small scale thematic mapping. Generalized boundary files are clipped to a simplified version of the U.S. outline. As a result, some off-shore areas may be excluded from the generalized files. A simplified U.S. outline is available for download for reference (500k, 5m, 20m). For more details about these files, please see our Cartographic Boundary File Description page.
