by Arndt 28 Jul '15

Hello, on a Mac System, BaseCamp dont´t show a mapname. In the List is an emty Line. I build the tdb after building the map. This are the options: family-id=2020 product-id=1 region-name=SpeicheCanaren description=SpeicheCanaren series-name=SpeicheCanaren family-name=SpeicheCanaren area-name=SpeicheCanaren overview-mapname=SpeicheCanaren show-profiles=1 tdbfile When i build the tdb with gmaptool, the name is OK. What ist missing? I have taken both tdb at this email. SpeicheCanaren.tdb is the one buid with mkgmap mapset.tdb is build with gmaptool Thank you for help. (gmap build with Garmin MapConverter, both, tdb with mkgmap and tdb with gmaptool) Best regaards Arndt

routing bug after r3602
by Minko 28 Jul '15

28 Jul '15

Hi, On the Dutch osm forum a routing bug was reported, http://forum.openstreetmap.org/viewtopic.php?id=31714 It is this route in Amsterdam: http://osrm.at/dR7 I have traced it down and found out that this bug is introduced between mkgmap-r3602 and r3616, the car routing now makes a detour via Olympiaweg/Olympiakade like http://osrm.at/dRh

Commit: r3625: fix possible routing error caused by wrong bearing calculation: The search for a non-equal point stopped too early
by svn commit 28 Jul '15

28 Jul '15

Version mkgmap-r3625 was committed by gerd on Tue, 28 Jul 2015 fix possible routing error caused by wrong bearing calculation: The search for a non-equal point stopped too early The error was old, but more likely to occur since the merge of the housenumber2 branch (r3605), as this branch might add number nodes which with equal coordinates as existing routing nodes.

Question about non-routable ways removed by WrongAngleFixer
by Carlos Dávila 28 Jul '15

28 Jul '15

There are several warnings in my log of the type below. I have check some of them and they all seem to be waterway=* ways. Why are these waterways (and no others) removed? Could it be avoided? (WrongAngleFixer): non-routable way 183447340 was removed (WrongAngleFixer): non-routable way 358689387 was removed (WrongAngleFixer): non-routable way 358689379 was removed There are also some warnings referring to mkgmap generated ways that can't be checked. These warnings seem useless. Perhaps a check to omit ways with id greater than a given number could be used: (WrongAngleFixer): non-routable way 4611686018427769516 was removed (WrongAngleFixer): non-routable way 4611686018427769586 was removed (WrongAngleFixer): non-routable way 4611686018427769437 was removed

Commit: r3623: Only produce a warning about a missing motorway ref when the node is a highway=motorway_junction.
by svn commit 27 Jul '15

27 Jul '15

Version mkgmap-r3623 was committed by gerd on Mon, 27 Jul 2015 Only produce a warning about a missing motorway ref when the node is a highway=motorway_junction. Carlos Dávila: Warnings about motorway exits in mkgmap.log include cases were motorway_junction is placed on motorway_link ways. According to wiki [1] motorway_junction may be used not only on motorway, but on other ways with named or numbered junctions, such as [2]. IMHO mkgmap shouldn't throw a warning in those cases. Regarding highway=services, if I recall right, it could be used time ago for exits that lead to service areas, but according to current wiki description [3] they are now only used for the place near the motorway where you can get the service (fuel, food, etc.) and then there's no need for them to be placed on a highway=* way. Warnings from places like [4] doesn't make much sense. Could it be reviewed to avoid checking things that don't need to be fixed?

Garmin bicycle routing algorithm
by Leonardo Brondani Schenkel 21 Jul '15

21 Jul '15

Hello, I apologize if this question is off-topic for this list. I am trying to get an idea about how the bicycle routing of Basecamp 4.4.8 works (or eTrex 20x, which is the unit I have) and how it differs from car/automotive routing. I wonder if others in this list could enlighten me. From the information I was able to gather, automotive routing works like this: - fastest speed: gives preference to higher road_class - shortest route: disregards road_class, calculates shortest route In both cases road_speed is only used for ETA and not route calculation (or has a very low weight). However, does bicycle routing works in the same way? I found confliction information on this point: when using 'fastest speed', some say that *lower* classes are preferred (due to roads being less busy) but most dedicated cycle maps that I have encountered (for example ligfietser's most excellent OpenFietsMap) use higher classes for more desirable roads and claim that the map can be used in both automotive and bicycle mode. And what about 'shortest route': does it disregard road_class like automotive mode? And how 'bicycle' and 'tour cycling' differ? I'm going to create a custom OSM map and a custom style in order to get some more clues and share the findings with the list but I would appreciate if somebody with the knowledge could shed some light into these issues. Cheers! // Leonardo.
