See https://en.wikipedia.org/wiki/Scale_(map)
Scale (e.g. 1:10,000) is a paper cartography term, it makes little sense
for computer displays especially for web view. So as a parameter that
controls what should be shown on the map when an object is centered on, I
chose dim(ension) which can be used objectively to calculate zoom, scale,
magnification or whatever is used n a particular mapping system.
