<body class='hmmessage'><div dir='ltr'>Hi Andrzej,<br><br>yes, mkgmap evaluates the tag "junction=roundabout",<br>no matter what type the road gets.<br>In trunk this is only used to decide if check-roundabout<br>must be used, in the branch it is used to group<br>all roundabouts at the beginning of table A.<br>That's why I hoped that the type 0xc is not needed<br>to get hints for the right exit point,but<br>it did not work.

Commenting the roundabout <br>> block clears problem, but if you instead change objects 0x0c into some <br>> other road, then problem remains.<br>> <br>> More precisely, I think route is correct, when roundabout get the same <br>> object as main road, but if roundabout is a different object (not <br>> necessary 0x0C), then calculation is wrong. Maybe reason is a turn angle?<br>> <br>> In my test detours contain roundabouts too. And if I set avoidance to <br>> roundabouts in BaseCamp, then detour changes, which suggest that <br>> roundabouts aren't the main reason of detour.<br>> <br>> I think mkgmap processes tag "junction=roundabout", even if there is no <br>> roundabout object 0x0C. After commenting the roundabout block, avoidance <br>> in BaseCamp still works. But avoidance doesn't work with following line <br>> in style:<br>> <br>> junction=roundabout & highway=* {delete junction}<br>> <br>> Side note: there is no verification of "class=" value. If I set <br>> "class=6" then mkgmap crashes with array index out of bounds exception.<br>> <br>> -- <br>> Best regards,<br>> Andrzej<br>> _______________________________________________<br>> mkgmap-dev mailing list<br>> mkgmap-dev@lists.mkgmap.org.uk<br>> http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev<br></div> </div></body>
