[mkgmap-dev] mkgmap-dev Digest, Vol 153, Issue 40 Resolution 23 raster problems

Tue May 4 12:19:46 BST 2021

Wow - looks really good. The main problem I feel is now that sometimes
highways you can see both directions apart - while before this was less
rare - or lost in the jaggedness.

--x-simplify-filter-line-errors=23:3.6,22:4.2,21:5.4,20:6,19:7,18:7.5,16:8,15:9
--x-simplify-filter-polygon-errors=23:4.6,22:7,21:8,20:9,15:10
--polygon-size-limits=24:16,23:14,22:12,21:11,20:10,19:9,18:8,17:7,16:6,15:5,14:4,13:3,12:2,11:0,10:0
seems to give pretty nice results - and much faster on my Garmin 600 at
lower resolutions.

I guess those highways with dual directions are much harder to solve...
