pment list for mkgmap Betreff: Re: [mkgmap-dev] Empty rectangles in map Hi Gerd Here is the change that always splits polygons into subdivisions by dividing along the internal boundaries rather than clipping. It is more efficient and the empty rectangle problem goes away. Ticker On Wed, 2021-04-2

Hi Gerd I think I'm getting somewhere with this and will try and have a proper fix in a day or so. It is related to subdivision splitting. Ticker ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk https://www.mkgmap.org.uk/mailman/listinfo/mkg

Hi Gerd A few more things I've discovered. GPSMapEdit will show bands of emptyness for a thin, correct, slice when you zoom out but with the view zoom level locked at a higher resolution than it expects. This confused some of my previous findings. Changing some sizes changes the behaviour and I

Hi Gerd More more testing with standard style / options etc. As well as --order -by, I had some level params that confused. With GPSMapEdit at Zoom level 2, there is a wide cut from the LHS forest triangle to the holes around 54.9953,-58.2209. It seems to be the total height of the holes. Simila

Hi Gerd Just tried this with latest trunk and my standard environment (mainly --order-by-decreasing-area and get very inconsistent results. On GPSMapEdit seems reasonable - shows forest triangle and, within, a small area with a number of holes. MapSource shows a white square, no forest colour a
