Re: Programmvorstellung: Datenkacheln erzeugen mit Mapsplit

Danke für den Tipp, Peda.

Mittels "-Xmx700M" und fast keinen swappen scheint es zu funkionieren:

$␣ulimit␣-Sn
4096
$␣ulimit␣-Hn
10240
$␣./mapsplit␣./mittelfranken.osm.pbf␣/tmp/tile␣-s=4000000,500000,200000

Interessant ist, das ein aus mittelfranken.osm.pbf per osmconvert geschnittenes Nürnberg nicht funktioniert:
