Minor issue with road angles
http://www.openstreetmap.org/?lat=53.71858&lon=-2.62873&zoom=16&layers=B000F... I was recently travelling south down the M61 and turned off this to head east along the M65. After joining the slip road from the M61 the directions I were given were to keep right to the roundabout and then take the 1st exit off the roundabout. As you can see there is a feeder lane from the M61 slip road onto the M65 slip road so the roundabout is clearly not the best option. I don't recall this ever happening before so I can only presume it's related to the arc tweezing stuff that was committed recently. I used mkgmap r1280 and the following command line to produce the map java -Xmx2048M -Dlog.config=$abspath/logging.properties -jar mkgmap.jar --adjust-turn-headings --remove-short-arcs --drive-on-left --check-roundabouts --add-pois-to-areas --latin1 --gmapsupp --route --style-file=$stylefiles --max-jobs --code-page=1252 --country-name="Great Britain" --country-abbr=GB --tdbfile --tdb-v4 --description="Map of GB" --family-name="Great Britain" 700000??.osm $contourdir/uk/*.osm >> debug.txt 2>&1 Cheers Paul
Hi Paul,

Good catch! Yes, it's better in the case of a link road leaving another link road to not increase the angle because then you won't suffer the extra time penalty and being told keep left/right makes as much sense as turn left/right. I will be committing a fix later when I've tested it some. Cheers, Mark PS - that junction looks too blue to me! should all the ways be motorway links?

So I was back out this way again tonight and with r1287 I just received a simple Keep left to M65 which is what I would have expected. As to it being too blue it's simply a junction of 2 motorways so I would expect it to be all blue. Possibly the link road to Walton Summit should be something else but it's not my local area Cheers Paul

The Walton Summit road is AFAIK also motorway: http://www.pathetic.org.uk/secretive/walton_summit_motorway/ Dermot -- -------------------------------------- Iren sind menschlich
