[mkgmap-dev] Optimization in overviev2 branch

Wed May 15 17:21:04 BST 2013

Hi all,

I've committed r2612.
This creates much fewer polygons, esp. in combination with the SeaGenerator and large sea areas.
For a map of South America, the gmapsupp size is decreased by 20MB, the overview map size 
went down from 12 Mb to 3.9 Mb.

It also seems that this fixes an issue with MapSource / Basecamp: If you max zoom out of the map created with r2610,
the programs show many white rectangles for the sea areas, with r2612 this is no longer the case.

Gerd
