[mkgmap-dev] Not much progress on inter-tile routing yet

Not much too report after spending quite a few hours on this last night. I am trying to understand why some inter-tile connections are good and a lot are bad. I have tried moving points around and rounding coordinates and stuff like that but with no knowledge gained about from the fact that it appears you can zero the bottom 2 bits of the lat/lon values in the nod3 record and it doesn't stop a good inter-tile connection from working. If you zero 3 bits, that stops it being usable. I have tried limiting the size of the NOD3 section to 16 entries, it made no difference. I shall work some more on it tonight. Cheers, Mark
