With Google Maps and Google Earth so commonplace now, GPS everywhere, and with websites such as our own Metafilter making use of latitude and longitude did you ever stop to think about how all this latitude, longitude and height above sea level works? The UK's Ordnance Survey explains it all in A Guide to Coordinate Systems in Great Britain. Discover that different coordinate systems might differ by as much as 200m, and that your house may be moving as much as 1m up and down each day relative to the centre of the Earth, and many other bits of geographical interest.[more inside]

GeoBloggers
The natural extension of Google and Flickr so that personalized maps are created of geotagged photos. Add "geo:lat=xx.xxxx", "geo:lon=xx.xxxx" and "geotagged" to your Flickr tags and they go into the system. The possibilities are pretty wide open.
Ain't technology grand?
