Hi all, I think it is ready for a first public test . Improvements: 1) Faster (esp. with large files), mostly because of an additional thread for OSM reade. If you are interested, please play with the max-threads value. On my machine with a core i5 I see better results with max-threads=6 than with the default ("4 auto"). 2) Splitting planet with a rather small max-nodes value like 800000 now stores ~ 41000 of possible 65535 entries, with r442 I saw > 58.000. If you reach a value of > 60000 in one of the "number of area dictionary entries: xxxxx of 65535" please contact the list. This limit may be increased to ~ 2^31 but with a larger memory footprint. 3) Some optimizations in the memory footprint of the custom maps may allow higher max-areas values. I've changed the default for max-areas from 512 to 2048, this should work with typical PCs. See http://www.mkgmap.org.uk/download/splitter.html Gerd
