Still problems with remove-short-arcs
by Carlos Dávila 31 Oct '13

31 Oct '13

I still get some wrong routing at some roundabouts using remove-short-arcs=0. See attached screenshots. At http://osm.org/go/b_YMZ7sDP-- MapSource makes a detour to avoid the roundabout, due to a sharp angle that is introduced by remove-short-arcs=0. If I use rsa=3, the route goes through the roundabout, but the exit number is wrong, because the incoming road and the first street are joined at the same node of the roundabout.

Commit: r2795: Minor correction to getAngle.
by svn commit 31 Oct '13

31 Oct '13

Version mkgmap-r2795 was committed by gerd on Thu, 31 Oct 2013 Minor correction to getAngle. Always use c2 to calculate the initial bearing. (c1.bearingTo(c2) != c2.bearingTo(c1) - 180) The previous version returned wrong values when the distance between c1 and c2 or c2 and c3 was large. See http://www.movable-type.co.uk/scripts/latlong.html

Is it possible with --add-poi-to-lines option and style rules to create pois only for ways with a min/max/equal length?
by Anna Leuchter 29 Oct '13

Hi Henning, 1. >Option could be: --add-poi-to-routes="100,1000,10000" Does this mean that every 100 meters + every 100meters + every 10000 meters of the route a mark would be set? So at 1000m there would be 2 marks? One for 100m + one for 1000m? This imo wouldn't make sense for waymarks or? 2. if way is part of multiple routes in this case, like actually with the "--add-poi-to-lines" option, the created marks also might created at the same distances/place and than overlaying each other. Hardley affected will be only those routes which starts at the same point and following partially the same way. Anyway that can happens to in the other cases if routes only share some intermediate part. In that case the those overlaying marks must be shifted a bit, so that all are visisble. regards Gert

Hi Henning, >Typical Garmin software shows all POI, if you click next to them. Yes, i know. But mayor intention of that waymark signs is to have a better visualization of hiking routes on the map. (Like we have it in paper hiking maps) If the marks overlaps this visualization gets lost for the overlayed signs. >I don't think that shifting is a good solution, because the distance >depends on zoom level and on the number of routes. Yes, i'm aware of that problems and think that it's difficult finding a perfect solution for all situations(zoom, route count...) Regarding zoomlevel it will always be a compromise: Having a parameter with whom you can determine the shift which will be used in that case, could help you to find the compromise which fits best your needs. Regarding the count of routes which shares the same way: Maybe here the count of routes which will be shifted(if needed), can be restricted to e.g. the first 3 matching routes or handeld via parameter, too. With both parameter imo you have not perfect but good tools to find a good compromise in creation of that points. For more perfection the angle of turns in the way could beused to determine if a mark is needed or not. Straight ways needs less marks than curvy ways. But i don't have any idea how much effort it is to implement such things. regards Gert

final fields in Coord
by GerdP 28 Oct '13

28 Oct '13

Hi programmers, I'd like to add a method like Coord.moveTo(int lat, int long) to set new values in an existing Coord. To do that I have to remove the final attribute from the latitude and longitude fields. Is that known to cause problems? If not, the method could also be used to simplify removeShortArcs (we could drop the IdentityHashMap replacements and other stuff around that) Gerd -- View this message in context: http://gis.19327.n5.nabble.com/final-fields-in-Coord-tp5783182.html Sent from the Mkgmap Development mailing list archive at Nabble.com.

Commit: r2788: Revert previous change to styled converter and modify the test code instead.
by svn commit 28 Oct '13

Version 2788 was committed by steve on Thu, 24 Oct 2013 Revert previous change to styled converter and modify the test code instead. Now create a new converter for each operation. I don't think calling end() more than once is a good idea even if it can be made to work.

Hi WanMil, Hello Henning, thanks. i had been afraid that it does not work. Wouldn't it be enough to add something like a mkgmap:line2poilength to the poi which than can be used later in style.? Ok, probably is the idea of Henning the better solution. regards Gert

Hi, i try to create a map including hiking trail markings usin r2748. So far i succeded using --add-poi-to-lines option and making the needed setting within relation and points style files. For every way part of a hiking route a poi is created. But to prevent map to be overcrowded by those trail marking pois, i would like to create those kind of POIs only for way parts with a minimum length. Something like "highway=* & length() >100 {set mkgmap:line2poi=false}" in the lines file, doesn't seems to work. (As far as i read meanwhile, points are processed before lines, so this can't work.) Is there a way with actuall code version to achieve it? best regards Gert
