I would use --generate-sea=polygons,extend-sea-sectors, I think it gives better performance in Mapsource or GPS (please speak up stranger if you had time to really compare and tell if it is advisable to use or not). IMHO the main problem is here that mkgmap still has no decent overview map (ideally we would have a non empty overview map). My top3 of what mkgmap still is missing or doing wrong: 1. Address Search only working in Mapsource (or inside active tile on "old generation" GPS) 2. Overview map empty and a bit incorrect 3. Routing over tile boundaries in Mapsource -if solved the overlap should not be needed (size decrease). Once 1-3 are implemented, mkgmap has no more disadvantages at all compared to cgpsmapper pro (costing big $$$$), and many many advantages. It really shows how successful open source is. BTW - I would have guessed that sea polygons will still take ages until correctly implemented (on the other hand I thought 2-3 month ago it will only be a matter of days until address search works not only in Mapsource but also on GPS correctly). In my opinion less important/major things to get right: # transliterations (there seems to be some good work according to the osm forum mkgmap section) # coping better with contourline maps (e.g. some possibility to get rid of those long straight lines that happen on data holes) # using units. most importantly make it possible to calculate from miles to kilometers, from feet to meters... (would be enough if one could have multiplication with factors in style-file). # I'll certainly have more ideas/wishes once the above is implemented.
