Hi Gerd When loading precomp sea tiles, shouldn't SeaGenerator should replace all nodes on the edges of all the precomp tiles used with nodes from a shared coordPool. Maybe it needs to replace even more to cover the cut lines. Ticker On Thu, 2021-05-20 at 14:09 +0000, Gerd Petermann wrote:
Hi Ticker,
reg. Also thinking that shapeMerge might need to operate at highPrecision : ShapeMerger doesn't compare positions, it checks for identical Coords.
For the overview map the ovm_* data is read and MapBuilder.prepShapesForMerge() is used to make equal Coord instances identical. This is not 100% safe, no matter what precision we use, when the original data has touching rings with equal, but different Coords the OverviewBuilder can see identical ones.
