Hello.
I am trying to create a binary-format
for storing OSM-data.
( http://wiki.openstreetmap.org/index.php/User:MarcusWolschon%5Cosmbin_draft#nodes.obm
)
I am looking for advise on how to create an on-disk index in one
dimension (element-id->offset where it is stored)
and 2 dimensions (bounding-box->nodeIDs and boundingBox->intersecting
bouding-boxes
of ways).
Thanks,
Marcus
