[mkgmap-dev] Still problems with lakes

@GerdP:

Some ideas concerning the "huge polygon problem":
- huge polygons are rare
- a broken polygon leads to an ugly (amateur like) map
- it's hard to find all broken polygons in a map manually

Some questions concerning a solution:
- is it possible to implement a "huge polygon" parameter ?
- the parameter acts as threshold and triggers splitter for extra processing
- the parameter could be the area (e.g. 2000 sqkm) or circumference (e.g.
1000 km) of an "huge" polygon

If the calculating of all polygons has a large negative performance impact:
- is it possible to identify the huge polygons in an extra (on demand)
splitter run ?
- the result could be a list with all identified huge polygons (generated
only once)
- this list is than the input for the essential splitter run

What do you think ?

Regards Klaus

PS: What is the exactly influence of the overlapping parameter concerning
the splitting of (huge) polyons ?
