[mkgmap-dev] --make-opposite-cycleways option

Wed Mar 4 05:30:50 GMT 2015

Hi Mike,

as I said, I'd be more happy to have a patch that remove's the option
and shows how to change the default style instead to get the same result 
as with your patch.

Your patch tries to remove all kinds of tags which might lead to wrong
routing:
+        cycleWay.deleteTag("vehicle");
+        cycleWay.deleteTag("motor_vehicle");
+        cycleWay.deleteTag("carpool");
+        cycleWay.deleteTag("delivery");
+        cycleWay.deleteTag("emergency");
+        cycleWay.deleteTag("foot");
+        cycleWay.deleteTag("goods");
+        cycleWay.deleteTag("hgv");
+        cycleWay.deleteTag("motorcar");
+        cycleWay.deleteTag("motorcycle");
+        cycleWay.deleteTag("psv");
+        cycleWay.deleteTag("route");
+        cycleWay.deleteTag("taxi");
+        cycleWay.deleteTag("bus");
+        cycleWay.deleteTag("truck"); 

Please explain why you remove route=* .
I think that one should be kept.

Gerd

HI Gerd, the attached updated patch adds a line to the default style that can be uncommented if you want to see the opposite cycleway names as they are currently. Regards,Mike From: Gerd Petermann [mailto:gpetermann_muenchen at hotmail.com]

I think you are right  regarding the access tags.
The current solution in combination with the default style
might route a truck through the wrong direction of a oneway.
Thanks for pointing this out.

If I got it right, most style developers don't use this option,
they prefer to have the logic in the rules.
Maybe this is another argument to remove the option
instead of adding code to make it work in special cases?

Is anybody able to change the default style so that it produces
the same result ?

Subject: [mkgmap-dev] --make-opposite-cycleways optionDear all,

When using the --make-opposite-cycleways option, I notice that the address
index adds a road name of the actual road name suffixed with " (cycleway)".
For me at least, this is undesirable. Also the generated name does not
conform to the OSM naming convention of not including any descriptive
information in names. I therefore propose that the name of an opposite
cycleway be set to the same as the original road name, and that users who
want to name the opposite cycleway differently should use the style file to
rename it.

In looking at the code that produces the opposite cycleway, I also believe
there is an error in the way it handles access tags - the code currently
sets access=no, bicycle=yes and foot=no, but ignores all other access tags.
Hence if (for example) the road has psv=yes on it, the generated cycleway
will also have psv=yes (unless I am misunderstanding something in the
handling of access tags). 

I therefore submit the attached patch for trial.

Regards,
Mike
