First step builds the maptiles with Xmx3000M, so that java not use the harddisk to swap, cause that makes the PC very slow. The ovm-work files may not be deleted for the overview map.<br></p><p>The second step with -Xmx10500M builds the index and the overview map. The taskmanager show maximal ~9GB in use. The Speiche_Europa map has ~20GB.<br></p><p>Special thanks to Gerd, who show me many things to improve my map building procedere!<br></p><p>Best regards<br></p><p>Arndt<br></p><p>speichenkarte.de<br></p><p><br></p><p><br></p>.<p><br></p><blockquote><p>Gerd Petermann <GPetermann_muenchen@hotmail.com> hat am 18.
