Curvy routing support: new function?
by Manfred Brenneisen 01 Aug '14

01 Aug '14

Hi all, Garmin offers "curvy roads" preferences for their zümo 390 and 590 devices. https://buy.garmin.com/en-US/US/on-the-road/motorcycles/zumo-390lm/prod1382… I'm thinking about creating motorcycle maps for old 200 series. Might it be useful to integrate a curviness() function so that mkgmap can optimize for curvy roads too? It might also help do determine a better default speed for curvy roads for use with car routing. The curviness() value might be the overall absolute turning angle (in degrees) of a road segment divided by the segment's length. What's your opinion? Cheers Manfred Pseudo code might look like this: function curviness() { oldpoint=points(0) foreach (point of a way segment as newpoint) { d_x=(newpoint.x-oldpoint.x)/360*40000000*COS(newpoint.x*PI()/180) //in meters d_y=(newpoint.y-oldpoint.y)/360*40000000 //in meters length+=sqrt(d_x**2+d_y**2) angle=arctan(d_y/d_x) d_angle=abs(angle-old_angle) sgn_x=sgn(d_x) sgn_y=sgn(d_y) if ((sgn_x*sgn_y*old_sgn_x*old_sgn_y)=-1 && (sgn_x!=old_sgn_x)) d_angle=pi-d_angle // 180 degrees correction, otherwise north-south roads show strange results if (point>1) sum_angle+=d_angle old_angle=angle oldpoint=newpoint old_sgn_x=sgn_x old_sgn_y=sgn_y } return sum_angle/length } // perhaps simple multiplication is faster than 4 times sgn() functions?

Commit: r3319: Give a warning for probable cases of files with wrong encoding.
by svn commit 31 Jul '14

31 Jul '14

Version mkgmap-r3319 was committed by steve on Thu, 31 Jul 2014 Give a warning for probable cases of files with wrong encoding. The default reading routines in Java cause bad characters in unicode input to be replaced with the unicode replacement character 0xfffd. We detect this in the TokenScanner, and print a message with the file and line number. This will apply to all files that are read using TokenScanner, so probably everything other than the maps themselves. It is possible for a file that is in the wrong encoding to still be valid utf-8 although this would be rare, and you can always add a comment with some accented characters that is likely to fail when in the incorrect encoding. It does mean that you can't genuinely have a replacement character in your input. I don't think that this is likely to be a real problem, but we did have a few ourselves already, which have been removed by this patch.

AssertionError on turn restriction
by Minko 31 Jul '14

31 Jul '14

When I enable assertions (-ea) in my java command, mkgmap-r3300 is not able to produce one tile and gives an java.lang.AssertionError. I found out that the problem was this turn restriction relation, with type=restriction:motorcar restriction=only_straight_on http://www.openstreetmap.org/relation/3490966 In my relation style file I have the following line, to ignore those restrictions in my bike map: type=restriction:motorcar {delete type} I dont know if it's a bug in mkgmap or in my styles but it will produce no errors without this line, but then the restriction are applied and that's not what is intended. If I change the line into type=restriction:motorcar {delete 'type=restriction:motorcar'} then I get no assertion error. Now maybe this relation is a bad case because mkgmap seems to ignore it at all (via ways instead of via-points?) so I have adapted the relation a bit in JOSM to make it work with one 'from' way, one via-point and one 'to' way. http://mijndev.openstreetmap.nl/~ligfietser/test/map.osm I use in my relation file this line type=restriction:motorcar {delete 'type=restriction:motorcar'} Result is that in motorcar mode, the turn restriction is still active. So there is still something missing in the mkgmap code, also {delete restriction} didnt help here either, looks like that those lines are completely ignored in the relation file here?

Name Substitution not correctly working
by Felix Hartmann 28 Jul '14

28 Jul '14

1. There seems to be a problem with Chinese Tonemarks... e.g. on http://www.openstreetmap.org/node/244080668 name:zh_pinyin ~ '.*Shì' { set name:zh_pinyin='${name:zh_pinyin|subst:"Shì=>"}'; echo "rule working" } nor does name:zh_pinyin ~ '.*Shi' { set name:zh_pinyin='${name:zh_pinyin|subst:"Shi=>"}'; echo "rule 2 working" } work. 2. How can I remove parentheses from the name? name=* { set name='${name|subst:"(=>"'} name=* { set name='${name|subst:")=>"'} Is not working. Or better it gets called but I loose all characters in Japanese or Chinese... e.g. here: http://www.openstreetmap.org/node/569005420 -- keep on biking and discovering new trails Felix openmtbmap.org & www.velomap.org

Basecamp shows series-name as blank on MacOSX 10.9
by Andrew Gillespie 28 Jul '14

28 Jul '14

The series name for the map I build shows as blank in Basecamp's map selection dropdown on OSX 10.9. When I install the same map on OSX 10.5 Basecamp shows the name as normal. I have tried rebuilding the map with various names for --series-name="whatever" but it still happens. Has anyone solved this problem?

How can I test if "(" or ")" is part of name
by Felix Hartmann 28 Jul '14

28 Jul '14

I have a problem that I cannot escape brackets when trying to find out if they are part of the name... name ~ '.*(' { } is not working of course. However ^ is not able to escape a bracket... name ~ '.*^(' { } Is there any way to find out if there is a () in a name? (the reason for this is that I want to know in Japan if the name is only in Japanese, or in Japanese (English). -- keep on biking and discovering new trails Felix openmtbmap.org & www.velomap.org

Incorrect compilation of grid lines
by Roger Calvert 28 Jul '14

28 Jul '14

I have a file containing the British National Grid lines, as printed on Ordnance Survey maps. This can be found at http://www.rogercalvert.me.uk/osm/GBGrid/GBGrid.zip (this contains two files, they are the same except for the addition of the 'version' tag in the GBGrid06.osm file). I compile this file with mkgmap and overlay it on my GPS map. This works correctly with mkgmap 2654 and It displays correctly in JOSM. With mkgmap version 3241, the lines are misaligned and out of position. The behaviour is the same on MapSource, BaseCamp and my device. No error messages are produced. (I have not used any versions of mkgmap in between these two). My style file allocates codes in the 0x10300 range to these lines, but the effect is the same when I use code 0x21 (contour) for all lines. Attached are screen dumps for a small part of the map, from JOSM, mkgmap 2654 and mkgmap 3241, and also the batch file I used to compile it. I would greatly appreciate any advice. Many thanks, Roger -- ------------------------------------------------------------------------ Roger Calvert http://www.rogercalvert.me.uk ------------------------------------------------------------------------

Merge maps with mkgmap
by Kristoffer Malmström 27 Jul '14

27 Jul '14

Hi, i am having problem with merging garmin image files that i have generated from osm. I have also generated a image with contourlines. I am trying to merge them together, and there is no problem merging them, but the name of the map changes to "OSM street map" and there is only 1 "layer" or what they should be called, showing in a Garmin GPS unit. I have merged maps together a lot of times and then i have got like Countrymap as one option and Contourlines as another option in the map settings in gps unit. But now i don't get it working, maybe i am missing something. I am using this on the country image file: --latin1 --draw-priority=20 --route --process-destination --process-exits --drive-on-right --check-roundabouts --road-name-pois --make-poi-index --adjust-turn-headings --preserve-element-order --make-opposite-cycleways --remove-ovm-work-files --location-autofill="bounds, nearest, is_in" --levels="0:24, 1:22, 2:20, 3:18" --overview-levels="4:17, 5:16, 6:15, 7:14, 8:12" --max-jobs=2 --product-id="1" --family-id="355" --mapname="33110000" --country-name=SWEDEN" --country-abbr="SWE" --description="Sweden OSM map by Malmis" --series-name="Sweden OSM map" --area-name="Sweden" --family-name="Sweden OSM" --show-profiles=1 --tdbfile --gmapsupp -c template.args And using this on the contourlines image file: --draw-priority=30 --transparent --merge-lines --levels="0:24, 1:23, 2:22, 3:20, 4:18" --family-name="Contourlines" --series-name="Contourlines" --code-page=1252 --latin1 --max-jobs=2 --tdbfile --show-profiles=1 --gmapsupp --mapname=333 --description=Sweden-Contourlines --area-name=Sweden contourdir/srtm/*.osm.pbf then when i merge them i use this: --gmapsupp contourdir/srtm/gmapsupp.img countrydir/gmapsupp.img / Kristoffer
