Hi // TODO need to change this private final int topBits = 15; the first level in the overview map? If so, then could it not be read directly from the detailed maps, rather than being a constant? I noted the TODO. Yes that is exactly right. It should be calculated so that the whole area

Hi, Since you know what you're talking about: is there a discussion, explanation or otherwise for the reason that you did not let the maps overlap? An overlap of 300 meters sounds like a good idea for the routing - but as said before, I'm saying this from a position of blessful ignorance.

Hi all, I tried to line up Splitter with the map boundaries; instead of having (hexadecimal showing) 63240008: 251000,25800 254800,38800, I had to use 63240008: XX,X 254c00,X). Now the tool tips would not show up in the +-250 meters around the boundary. Then I used: 63240008:

Hello list, I'm having a great time corresponding to myself here :) but these are my observations so far. Running Splitter, then Mkgmap.jar, then MapSetToolKit.exe, then Mapsource, the resulting submaps are shifted from their bounding box: they are about 2.4 kilometers left, up, from the map

Hi Since no one replies to my mail, I'll do it myself ;) Thanks for studying the problem so closely - it is very useful. What I found is the following. Splitting a file with a border will produce a file that has the exact bounds, without the overlap, in the resulting map. That is

Hi Valentijn, Did anyone else notice this problem before? Were you able to reproduce it? If it helps, I can prepare a map that will have a routing problem just at the edge (there's a biking tunnel that MapSource avoids, no matter how hard I try, while letting mkgmap render the map without a

Hello list, When trying to use a built map, I'm getting a bit odd results around the edges of tiles - at least, I think it's the edges. It's not exactly on the boundaries, but about 2.5 kilometers below the grey lines that show up in Mapsource (I assume these are the tiles). But strangely, the
