Hi Thorsten, this reminds me on the osmid_v1.patch using fastutil.jar It is esp. usefull in this case because the memory requirements are caused by the huge number of coords. @Steve: Do you still plan to add it ? Gerd Thorsten Kukuk wrote

as per http://wiki.openstreetmap.org/wiki/Mkgmap/help/options#Using_preprocessed_bo... , i tried to generate bounds myself from a planet boundary extract (prepared with osmconvert/osmfilter like in the instructions on the same page).
java -cp mkgmap.jar uk.me.parabola.mkgmap.reader.osm.boundary.BoundaryPreprocessor
<inputfile>
<boundsdirectory>
that run out of the heap space of 2300 megs. before i try experimenting further, how much heap space is required for creating planet bounds from boundary extract ? :)
You need at least 8GB of free RAM. And I would suggest Sun/Oracle Java, not IBM Java or openjdk.
