[mkgmap-dev] conversion bug, lost attributes

Sun Feb 16 21:14:26 GMT 2014

Hi,

I have found some rondos on map, which are drawn as a highway ramp. 
After examining sources I have concluded that this is a bug, junction 
tag is lost by mkgmap.

This is source object in OSM data:
http://www.openstreetmap.org/way/148247399

   <way id='148247399' timestamp='2013-09-22T10:46:06Z' uid='681295' 
user='przemas75' visible='true' version='13' changeset='17971267'>
     <nd ref='258291555' />
     ...
     <nd ref='258291555' />
     <tag k='highway' v='trunk_link' />
     <tag k='int_ref' v='E 75' />
     <tag k='junction' v='roundabout' />
     <tag k='lit' v='yes' />
     <tag k='maxaxleload' v='11.5' />
     <tag k='maxspeed' v='40' />
     <tag k='ref' v='S6' />
     <tag k='source:maxaxleload' v='RozporzÄ…dznie Ministra 
Infrastruktury z dnia 8 czerwca 2011 r' />
     <tag k='source:maxaxleload:url' 
v='http://dziennikustaw.gov.pl/du/2011/s/124/703/D2011124070301.pdf' />
     <tag k='source:maxspeed' v='sign' />
   </way>

This is what I get, when using echotags to examine attribute in mkgmap:
148247399 - [ref=S6,int_ref=E 75,maxspeed=40,
lit=yes,oneway=yes,highway=trunk_link]

Attribute "junction=roundabout" is missing, which leads to wrong 
conversion. I have tested current mkgmap r2998 and branch r3053. I have 
attached OSM sample, which cause problem.

Here I have put some bigger samples of the same area:
http://files.mkgmap.org.uk/download/178/test2.7z

When compiling these samples, please observe way 202260411:
http://www.openstreetmap.org/way/202260411

This is similar rondo next to described above. Depending on sample size, 
rondo is converted to Garmin object 0xC - rondo or 0x9 - ramp. Rondo 
defined speed changes too, similarly to problem described here:
