If the width of Watercourse areas in the medium scale is greater than
50m, they become part of the small scale dataset.
7.
Administrative units and Administrative borders must share the same
geometry.
8.
Built-up Areas, Administrative unit and Watercourse Areas must be
simplified.
9.
If polygons of multi-part entities are smaller than 1 km

, they are
deleted.
10.
Administrative areas should be consistent with Built-up Areas and
Watercourse.
