Hello,<br><br>I &#39;m reporting some troubles to generate a map covering France+Switzerland. (--bounding-box top=51.08 left=-5.11 bottom=42.38 right=10.6 ) together with a (strange) workaround possibilty<br><br>My first try, with a splitter at --max-nodes=3200000 failed (too many roads in map, I&#39;ve been too greedy).<br>
So a retried without any max-node option in tile splitter, which gave me 195 tiles. <br>Then when using mkgmap r1907, <b>it crashed like this</b>:<br> java -Xmx2000m -jar mkgmap.jar --gmapsupp --style-file=../styles/routable/ --family-id=404 --family-name=OSM_Routable --route --add-pois-to-areas --remove-short-arcs --product-id=406 --draw-priority=0 -c ../work/template1.args  ../typ/GB404J.TYP<br>

<br>I tried then to &quot;group&quot; the 195 tiles by using:<br>java -Xmx2000m -jar mkgmap.jar --gmapsupp 19610*.img<br>This gave the same crash as above.<br><br>I tried then to group only the 100 first tiles with <br>java -Xmx2000m -jar mkgmap.jar --gmapsupp 196100*.img <br>
: no crash. I renamed the produced file into gmapsupp0.img. (Remark: I omit the .TYP as I don&#39;t really need it today, but I used this typ with success on small area maps.)<br>Similarly, I grouped the remaining 95 files with <br>
java -Xmx2000m -jar mkgmap.jar --gmapsupp 196101*.img<br>: again no crash, and i kept the result as gmapsupp1.img<br>Finally, I grouped the two subproducts by<br>java -Xmx2000m -jar mkgmap.jar --gmapsupp gmapsupp0.img gmapsupp1.img<br>
: no crash, the produced gmapsupp.img seems about to be usable in my etrex legend HCx (although quite slow and sometime crashing the etrex randomly (?), when searching a city name for example: the display fades away and the etrex gets off)<br>
Remark: The &quot;working&quot; gmapsupp.img has exactly the same size as the first one (totally unusable): 844,8 Mo (885850112 bytes).<br><br>
