Hi Felix,
Could the DP Filter not remove any points at resolution=24?
It doesn't do anything at that res.
Or is there another reason why many small polygons like buildings get
mashed?
Yes, the reason is that the coordinates round to approx the nearest 2m.
We can't do anything about that, it's what Garmin support.
okay I see. So the only real solution would be to have intelligent
filters moving the nodes to nearest 2m in such a way that there is
minimal loss of detail. Probably pretty CPU intensive and a lot of work.
So we have to live with it, in most places there is no real loss of
information anyhow.
In most cases there are not even any reductions in points needed to draw
the areas.
Agreed.
Cheers,
Mark
