Hi Thomas, oops, sorry, 3342 was a typo, should be 3314 ~ 2^32 / (360 * 3600) and 9942 ~ 2^32 / (360*1200) Gerd ________________________________________ Von: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> im Auftrag von Thomas Morgenstern <webmaster@img2ms.de> Gesendet: Donnerstag, 18.

Hi all,
see http://www.mkgmap.org.uk/websvn/revision.php?repname=splitter&rev=585
If I got that right you can use dem-dist 9942 for level 0 if hgt files are in 3'' resolution and splitter was executed with --align-for-dem=1200. For hgt 1'' files use dem-dist 3342 for level 0 and --align-for-dem=3600.
This should reduce DEM size a lot AND increase precision.
