[mkgmap-dev] Basecamp and NET/NOD changes

From Ticker Berkin rwb-mkgmap at jagit.co.uk on Tue Nov 26 16:31:44 GMT 2019

Hi Gerd

I've trying various things, like changing the TYP, removing road
-speed/class, ... to try and pin down this problem and generally, the
behaviour got worse.

I experimented a bit with your cut-down area: ticker-part-mod.zip but
had problems. Way -1477104 confused me for a while. So I went back to
the full tile. 

I've just updated to trunk latest r4387, removed all my changes and did
a clean rebuild, then, with --check-routing-island=-1 tried lots of
Motorcar routing in Basecamp and I find areas of my map still
misbehave.

EG:
"so23 0je" > "so23 0ps" straight line to a road a few roads east then
straight line back.
"so23 0qb" > "so23 9ru" straight line.

Generally, all routing fails around this small area, but other areas
north and west work fine.

The setup and data is identical to before but I've just been using the
northern tile (74210002.osm.pbf)

I'm just going to try some of these on the Device and pick some other
areas with island=-1 on the ticker-part-mod
