[mkgmap-dev] generating custom maps (stylesheet or typ files)
I want to create additional custom maps aside from the regular standard map from the default stylesheets. What I want are maps for cycling/mtb. But I am a bit confused with two options, 1. creating custom styles by editing the default stylesheet, or 2. creating typ files. Can somebody explain the difference of the two options?

Re: [mkgmap-dev] (almost) duplicated node issue
Wow... things get tough... I've three things to say in a single mail: First: I think the encoding is just a 24 bits rounding of the coordinates. You should know at the first run all the nodes that collapses in the same IMG point. But I understand when you say that is complicated to find all the collapsed nodes in a million nodes map. Well, after encoding you should order the nodes per latitude and then order the nodes with the same latitude per longitude. Then all collapsed nodes are in a row. (quicksort is able to sort a vector "in place" without memory wasting: in C I remember I ordered a vector of 1 million elements in few seconds). Second: But maybe the problem is somewere else, or there is a simpler solution then forcing a collapse of nodes: If the IMG specification accepts 2 (or more) independent nodes with the same coordinates (after encoding), maybe it is the routing info that should be encoded in some "smart" way (to be discovered...) that avoids routing engine hangs, infinite loops or errors. Or it could be just a "simple" mkgmap bug: the routing info of the two close nodes does not relates correctly to the two nodes individually. It looks strange to me the fact that the problem in one point creates routing errors rather far in the map. Like a mis-alignemt of routing info vectors vs. node vectors. Third: I made this further experiment you can reproduce: (1) compiled the osm file I've attached some mail ago: Routing error (2) I moved one node of the 2 almost duplicated 10 meters away, compiled the osm file again: NO ROUTING ERROR since the 2 compiled IMG do contain the same nodes, it should be easy for people who know IMG encoding and routing info encoding to discover the difference between the two IMG and understand what happened (a info vector shift, a missing info, a wrong info). Of course if you have a java debugger environment you can check variables before the IMG is even created (I think it's easier) Hope this help.

Re: [mkgmap-dev] (almost) duplicated node issue
Just a few thoughts... 1. Why not giving a special mark to such nodes which have been generated by a clipping process? Maybe there is own tag for this? Then you would know that merging is not appropriate. 2. And... please be careful when merging nodes which are parts of ways with different layers. These could represent separate floors of a public lift, e.g. 3. Is there special a tag for marking those nodes which must not be merged although they have the same coordinates? This tag could be used to prevent automatic merging.

I should think that it would be reasonably easy to merge close nodes using a first pass before any ways are processed. However, tricky issues remain. Like, how do you cope with the situation of a node being generated by the clipping process and that node is within the critical distance of an existing node on the same way?

Re: [mkgmap-dev] Bicycle routing, cycleway=opposite
Thanks to you all for the ideas! Now I see that a lot can be achieved by editing the style file. A lot good things, and a lot nonsense as well. ;-) The default style adds a "foot=yes" for cycleways, which should not be assumed as a default permission, imho. But I'm not sure about this. Bicycle routing against one-ways As far as I understand the style rules, I could add this one: bicycle=opposite { set oneway=no } Some other rules should be established too: bicycle=opposite_lane { set oneway=no } bicycle=opposite_track { set oneway=no } Having generated a map with this rules, it will be of no use for motor vehicles, of course. But as my only goal is to optimize a map for bicycles, that would be no problem so far. In the long run, this feature should be adapted so that the user can select at the GPS device whether bicycle routing or motorcar routing is to be used. Road preferences There is a key "road_speed" in the style file. I assume that this is meant to be a means for road preferences. What speed values are associated with this speed classes? E.g., is road_speed=4 twice as fast as road_speed=2? I ask this because I want to give cycleways a slight preference against other roads, and this preference should really be "slight".

[mkgmap-dev] (almost) duplicated node issue
Well, when a node is duplicated (I think, latitudes and longitudes matches up to the last digit), JOSM validator detects it as a map error and offers the possibility to automatically correct the issue. I think there are two cases: (1) the 2 duplicated nodes are not connected by any arc. Well, if JOSM collapses the two nodes in one, it connects each other arcs that weren't connected before. (2) the 2 duplicated nodes are connected by an arc (a zero length arc). Well, if JOSM collapses the two nodes in one, I guess it just deletes the zero length arc. But if the deleted arc was one way, the deletion makes possible routes that weren't possible before I want to say: duplicated nodes and almost duplicated nodes are map errors (expecially if they describe an highway). We do not know wich was the right intention of the mapper (make routing possible/impossible). I think that the best we can do when mkgmap finds 2 nodes that encode in the same IMG point (so in both cases: duplicated nodes or almost-duplicated nodes) is to collapse the 2 nodes in one node exacly as JOSM validator would do if they were duplicated. Does it sound good?

I know about IMG resolution, Mark. That is the reason I think there is a bug.
