Moin, in the style rules documentation in the WIKI it is stated, that a comparison of numeric quantities is possible, e.g. "maxspeed>=30". Is this really working? I tried the following example: In my osm file I had five ways: <way id='-9902' action='modify' visible='true'> <nd ref='-9900' /> <nd ref='-9901' /> <tag k='highway' v='null_null' /> <tag k='layer' v='-1' /> <tag k='name' v='layer=-1' /> </way> <way id='-9912' action='modify' visible='true'> <nd ref='-9910' /> <nd ref='-9911' /> <tag k='highway' v='null_null' /> <tag k='layer' v='0' /> <tag k='name' v='layer=0' /> </way> <way id='-9922' action='modify' visible='true'> <nd ref='-9920' /> <nd ref='-9921' /> <tag k='highway' v='null_null' /> <tag k='name' v='layer!=*' /> </way> <way id='-9932' action='modify' visible='true'> <nd ref='-9930' /> <nd ref='-9931' /> <tag k='highway' v='null_null' /> <tag k='layer' v='1' /> <tag k='name' v='layer=1' /> </way> <way id='-9952' action='modify' visible='true'> <nd ref='-9950' /> <nd ref='-9951' /> <tag k='highway' v='null_null' /> <tag k='layer' v='+1' /> <tag k='name' v='layer=+1' /> </way> And in my style the lines-file contained the following rules: highway=null_null & layer<0 [0x01 resolution 10] highway=null_null & layer=0 [0x02 resolution 10] highway=null_null & layer>0 [0x03 resolution 10] highway=null_null & layer='-1' [0x04 resolution 10] highway=null_null & layer='0' [0x05 resolution 10] highway=null_null & layer='1' [0x06 resolution 10] highway=null_null & layer='+1' [0x07 resolution 10] highway=null_null [0x08 resolution 10] As a result I expected the following conversions 9902 -> 0x01 9912 -> 0x02 9922 -> 0x08 9932 -> 0x03 9952 -> 0x03 Against my expectations the conversions were the following: 9902 -> 0x03 9912 -> 0x05 9922 -> 0x08 9932 -> 0x03 9952 -> 0x03 What is wrong? - My understanding of the style rules? - The documentation of the style rules? - The behaviour of mkgmap?
