This seems to be a dramatic simplification, to the point where the results aren't helpful at all, unless I'm missing something.
A lot of this is private property. Offices, people's houses, a farmer's farmland. We can't go inside, or trample on the crops of farmers. Then you need to subtract roads - because you can't walk on a road and definitely not a motorway.
So really, shouldn't the land area used be the publicly accessible pedestrian area?
And I dunno about others, but my footpaths are less than a metre long in width in my residential area. In the commercial areas, they tend to be less than 6 metres.
