Hi all
In some major walking areas there are networks of paths with a few car
parks around the edge, normally set 100m or so into the park/woods. The
free maps one can obtain show suggested trails and these trails often
cross multiple car parks. The maps probably don't show a path within
the car p

Just another idea
Is it possible to make the car park a (pseudo) node that is on all the
paths that connect to the car park?

Hi John,
where would this node be? Think of L- or U-shaped areas around shops.

Hi Mike,
since nobody else responded: to be honest: I don't even know what this test is
about.
Maybe you can post a link to a flare road which should be flagged but isn't and
another one which is a false positive?

Hi Randolph
Some comments, embedded, on your changes.

Hi Gerd,
now this sounds at least a little promissing for overlays with little data.
I assume that my contourlines overlay that additionally holds the DEM
data for hill shading (europe is almost 4GB) can not be improved that way.
With the other overlays I'm a little lost on how to get bigger til
Hi,
I recently have noticed the following suggestion in mkgmap output:
"To reduce the run time, consider increasing the amnount of memory
available for use by mkgmap by using the Java -Xmx flag to set the
memory to more than 196700 MB, providing this is less than the amount of
physical memory
Hi Franco,
I did my test with an extract of all route=bicycle or route=mtb relations in
Europe. I used osmfilter for that with a statement similar to the one that is
used to extract the boundaries:

Hi Andrzej,
yes, there is an error, see

I didn't commit my patch because I have no experience with the internals.

Hi Gerd,
I see, not a simple problem. While the idea is nice, the actual
implementation looks problematic. Maybe better remove the message or
replace it with some general advice?

Hi Gerd,
the code checks that roundabout flares are oneway and point in the right
direction. However, it currently produces more false positives than wanted
results.
For example, the current version of mkgmap outputs the following false
positive messages:
