What follows is a RAR file of the Meridian 2 Shape data from Ordnance Survey in GML format.
Meridian2Shape-GML-Webcoding-V1.0.rar (136MB compressed) expands to around 2GB.
GML is a Geo Spatial XML format data set which is much easier (in my opinion) to process and use.
Look at the beauty of the UK road network. A few lines of code and 15 seconds processing and we have every a, b, minor, motorway and round about.
