[mkgmap-dev] Splitter problem: losing a track segment

Sat May 30 02:04:34 BST 2015

Hi guys,

I'm facing a problem in one of my maps, that is probably might be happening
in other places where I didn't see yet.
The problem can be seen in the figure below taken from MapSource. There is
a gap in a track on the border of the tiles:

So I started to analyze the problem step-by-step till find that the problem
was generated by Splitter (last version).

To simplify your analysis, I edited my .osm file before running Splitter
and remove all objects (nodes, lines, poi, etc.) not related to the
problem, leaving only the line where the problem happens. The result was
the file "93352150-Ribeirao_Preto.osm" attached, containing only this:

<?xml version="1.0" encoding="UTF-8"?>
<osm version="0.6" generator="TSuite 6.6.0.4">
<!-- === POLYLINE ROTEAVEL - INICIO: SP-255 DANIELLE
======================== -->
 <node id="576" lat="-21.9388623" lon="-48.3347007" visible="true"
version="1"/>
 <node id="805" lat="-21.8877920" lon="-48.2932640" visible="true"
version="1"/>
 <node id="806" lat="-21.8674906" lon="-48.2767485" visible="true"
version="1"/>
 <node id="804" lat="-21.8661147" lon="-48.2756044" visible="true"
version="1"/>
 <way id="803" visible="true" version="1">
  <nd ref="576"/>
  <nd ref="805"/>
  <nd ref="806"/>
  <nd ref="804"/>
  <tag k="highway" v="trunk"/>
  <tag k="name" v="SP-255 DANIELLE"/>
  <tag k="ref" v="SP-255"/>
  <tag k="addr:city" v="BOA ESPERANÇA DO SUL"/>
  <tag k="addr:state" v="SP"/>
  <tag k="addr:country" v="Brasil"/>
 </way>
<!-- === POLYLINE ROTEAVEL - FIM: SP-255 DANIELLE ========================
-->
</osm>

Then I ran Splitter on this file and the result was the file "93352150.osm"
(attached and compacted), whose content are the lines bellow:

<?xml version='1.0' encoding='UTF-8'?>
<osm version='0.5' generator='splitter' upload='false'>
<bounds minlat='-21.895751953125' minlon='-50.262451171875'
maxlat='-20.401611328125' maxlon='-47.548828125'/>
<node id='805' lat='-21.8877920' lon='-48.2932640'/>
<node id='806' lat='-21.8674906' lon='-48.2767485'/>
<node id='804' lat='-21.8661147' lon='-48.2756044'/>
<way id='803'>
<nd ref='576'/>
<nd ref='805'/>
<nd ref='806'/>
<nd ref='804'/>
<tag k='highway' v='trunk'/>
<tag k='name' v='SP-255 DANIELLE'/>
<tag k='ref' v='SP-255'/>
<tag k='addr:city' v='BOA ESPERANÇA DO SUL'/>
<tag k='addr:state' v='SP'/>
<tag k='addr:country' v='Brasil'/>
</way>
</osm>

Note that in the "93352150.osm" file is missing the node 576 definition
(i.e.: <node id="576" lat="-21.9388623" lon="-48.3347007" visible="true"
version="1"/>).
And this is the cause of the lost segment.

I'm running Splitter in the following way:

java -jar splitter.jar --split-file=93352150-Ribeirao_Preto.list
--max-areas=1024 --mixed=true --keep-complete=false --resolution=15
--output=xml 93352150-Ribeirao_Preto.osm

The above .list file is attached.

If this is not a Splitter error, please, let me know what I'm doing wrong.

Thanks.

Alexandre
