I defined a series of rectangular areas to extract from the UK planet.osm, 
and in order to avoid adding urban areas to the database, I had to exclude 
small rural areas near the big cities. The bounding boxes probably need 
finer tuning.

This probably arose in order to simplify my bounding boxes. I'll try and 
look into this.

The northern limit of my northernmost bounding box is somewhere near 
Hadrian's Wall - again I'll look into this.
