Hi Gerd
orderByDecreasingArea only has a param declaration and single use in
MapSplitter and its value transforms to MapArea.splitPolygonsI
a (final) field in MapSplitter?

sounds good to me. I once analysed why sub divs were split and found that
most times it was because of "too many points" or "too many lines", not
because
of "too much data in rgn",
Hi Gerd
One of the reasons I went along the PredictPoints route is that MapArea
was calculating the subDivision usage (number of items, amount of data)
based on totally unfiltered lines/polygons, regardless of the
resolution, so this was forcing splits where no need whatsoever.
I didn't want to

I think the problem is that PredictFilterPoints ignores the fact that the

Hi Gerd
Most of the changes that will make a difference to size are related to
MapArea/SubDivision contents and splitting hence ShapeMergeFilter
activity.
As far as changes in size between the versions:
3782-3784 should be similar and a little bit worse than 3781 because of
a fix to stop a
Hi Ticker,
I compared the sizes for a map of spain with and without option
--order-by-decreasing-area,
I always see larger files with r3784. With r3777 and r3778 the files are
typically a bit smaller
than with r3773.
Is there a good reason for that ?
