[mkgmap-dev] Warnings about correct ways produced by --check-roundabout-flares

Wed Aug 19 12:00:42 BST 2015

Using --max-flare-length-ratio some of the warnings disappear, but it 
seems to have quite a random effect or at least not as described in 
options file. Many ways longer than the specified value are kept in the 
warnings. Among the removed ones there are both valid and invalid 
warnings, so not too useful.
In addition to the examples below, there are also warnings about ways 
that are not connected to any roundabout:
Incoming roundabout flare road 
(http://www.openstreetmap.org/browse/way/319137664) does not start at 
flare? http://www.openstreetmap.org/?mlat=36.678070&mlon=-6.144893&zoom=17
Incoming roundabout flare road 
(http://www.openstreetmap.org/browse/way/31889812) is not oneway?
