It sure was an exageration. Indeed the best way would be to include he detailed stuff near the coastlines and waterways. I'm not sure you would save a lot, because e.g in Germany the waterways are quite close together. Could you render the outlines of settlements (landuse=residential) instead of all the residential roads. I know they don't exist for all of the cities, towns or villages, but you should save a lot of data. IMHO tertiary highways and up should be in the map since they are usually rendered in normal nautical charts also. I'd like to elaborate a bit more on the issue of areas to be downloaded. To conserve your server bandwidth you could make smaller sections. Someone who goes sailing in the Adriatic Sea might never have use for the mapdata in the Canary Islands, yet, as it is now, he has to download both. Why not group stuff more like the sea areas are named- Mediterranean East and West, Europe Atlantic Coast, North Sea, Baltic, South Chinese Sea, East and West Indian Ocean- you get the picture... One can always mix and match in mapsource. Right now the maps are divided up more like roadmaps, not by sea area. BTW, is there any documentation on the mapmaking process, like special OSeaM mkgmap stylefiles you guys are using, things you do to the OSM- file (like ripping out unwanted stuff etc.)? Is there something like a wikipage in case you want to roll your own maps?
