Hi all,
please try r4213 in the country-border branch, I think it is ready for merge
into trunk:
http://www.mkgmap.org.uk/download/mkgmap.html
I hope this description is clear enough, please suggest improvements /
corrections:
--add-boundary-nodes-at-admin-boundaries=NUM
This option controls how mkgmap calculates special routing nodes which
are needed by Garmin software to allow routing between different map
tiles.
These nodes are written to section 3 and 4 in the NOD file.
When a road crosses the tile boundary (bbox), the road is split at this
point and such a special node is written. This allows routing between
one set of tiles produced by splitter.jar. However, if you create a map
from different sets of tiles, those tiles are likely to overlap.
For the overlapping tiles, none of the entries in NOD3 match and thus
routing across tile border doesn't work when the route is not fully
covered by one of the tiles.
The option tells mkgmap to add special nodes whereever a road touches or
crosses an administratve boundary. The NUM parameter specifies a filter
for the admin_level. Boundaries with a higher admin_level value are
ignored.
The default value is 2 (country borders). Another reasonable value
might
be 4. A value less or equal to 0 tells mkgmap to ignore intersections
at
administrative boundaries.
