[mkgmap-dev] Useful routable line types

Sun Dec 16 16:40:53 GMT 2012

Hi Minko,

When responding to your e-mail I realised a mistake in the lines style file 
which throws everything out so I need to fix and re-work the test, hopefully 
with some more expected results.

0x05 should be accurate though, and what I mean by  'Opposite direction to 
that defined in JOSM only' is:

In the locally created map using JOSM all my test roads were created running 
from north to south. But 0x05 in the test (which I usually use for tertiary 
roads) was only routable south to north. For a automobile it would route 
down another road further away if trying to go north to south, for a walker 
it would show a dialog stating something like "Error: Failure to calculate 
route". For both it would route from south to north.

As for the rest (essentially everything >= 0x0a [it was an exceedingly 
menial task and instead of going from 0x00-0x1f my brain froze and went from 
0x00-0x31]), this all needs reworking and I'll give the results either later 
this evening or tomorrow. But preliminary results suggest there are many 
routes which both show as expected in Basecamp (i.e. as defined in TYP file) 
and are routable in both directions.

Note: initial tests are in Basecamp (and the odd confirmation in Mapsource) 
only, I have done no testing on a device and do not expect to do so until I 
have tested the first 64 codes (0x00-0x3f) in Basecamp. Additional test: 
removing name attribute so I know what Garmin thinks the line type should 
be.

All this has probably been done before somewhere, but it keeps me off the 
streets for a while ;-)

Geoff.

Geoff,
Interesting experiment.
What do you mean by 'Opposite direction to that defined in JOSM only'?
I dont understand that some lines not show in Basecamp if you use a TYP 
file?
Have you activated all line types?
I can see 0x11, 0x1e 0x1f with or even without typ file in Basecamp.

Another remark, 0x14 (railways) are not shown at lower zoom levels on a GPS 
device.
Only on the highest levels.
