[GraphHopper] has anyone customized an existing vehicle?

[Andrew Heard]

Hi Peter

Thanks so much for the reply. I really appreciate it.

>yes, that customization is possible
only possible by a programmer, not by an ordinary user; although I am a
retired C# programmer, my reading of the situation is that the Locus dev
Menion has taken GH and incorporated it into an add-on for Locus, that is
code I & you don't have, and just the whole learning curve for Android/
Java/ yet another development system, all looks too hard

>e.g. for bike the common super class 'BikeCommonFlagEncoder.java
<https://github.com/graphhopper/graphhopper/blob/master/core/src/main/java/com/graphhopper/routing/util/BikeCommonFlagEncoder.java>
'
wow, that's amazing, *so* much development in this project, this is where I
imagine BRouter is heavily script driven whereas GH has its logic in Java

>where different profiles like racing bike
this may be a question for the Locus guys instead (unless you are aware of
the app), but what is the mapping from the 5 Locus icons, two cycling
profiles boxed below, and to the GH  racing bike profile?

>Well, not really obscure, the track is marked with bicycle=yes and as the
road is highway=primary road
>graphhopper is trying to avoid that. What we could do is also trying to
avoid
>sac_scale=hiking or surface=gravel (maybe the latter is already done).
sorry, I was sounding more emotional than rational, the tags are quite
reasonable & I wouldn't change them, but yes the key may be
"surface=gravel", if I select Fast bike in Locus, and if the mapped GH
profile is "racing bike", then it makes no sense (to me) to route via a
gravel hiking track parallel to a primary road of the same distance

however that I see it the beauty of BRouter, everyone is going to have a
different opinion of what a good route is, and they can alter or create a
new script, or in some cases substitute one script for a more suitable one
where they are not knowledgeable enough to make the changes, for example I
have seen fast bike, cycle touring, recumbent, MTB, blind walker scripts -
amazing

Is there anything as a non programmer I can do to

   - enabling logging (I see there is extensive logging in the Java code)
   - check which profile is being used, eg. confirm racing bike

I would be tempted to dive into the code but as I say, I think there is
Locus code connected in there too that I have no access to. May I will ask
the Locus devs.

Thanks again for your time, sorry I may have further questions later.

cheers

Andrew
