OSM UK car parks

This is an experiment to look at car park capacity for UK car parks and compare it to the calculated areas based on the polygons. Where car parks are marked as parking=multi-storey and the building:levels is greater than 1, the area is multiplied by the building:levels and these are shown in green. Any parking=multi-storey with building:levels not greater than 1 are shown in red as these are likely to be wrong. The data are loaded from GB-parking-with-areas-capacity.csv.
