You see: almost nothing. Streets, building plots, area sizes. But contour lines are missing, for example. What do the purple lines mean? And, as so often: the bad practice of zooming in on the individual plot without showing the surroundings (or even specifications from the development plan). Well, for plots in the same row it will probably be the same building field and the same usage template. But depending on the relevance of the reference height (e.g. street height of the level longitudinal or sloping cross street), painful differences can still lurk there.
