Openstreetmap import limitations?

himawari

I'm trying to import an openstreetmap database of a fairly large area, file size is a few 100 Mb. The import takes very long (hours to days) and the resulting *.odb database is incomplete, many of the buildings are missing. Also, imports of *.osm databases of different sizes result in incomplete *.odb databases of (nearly) identical size.

Is there a limit on the number of buildings in an *.osm database that Wallman can handle? And if so, what is that limit? Is there any way to correctly import larger *osm databases?

Is there a way to accelerate the import? (I've already disabled generating the *.add file and opening the database after import.)

@himawari , I would suggest that you split your database into smaller datasets. This will accelerate the conversion of each, and you can then combine them again in one urban database once converted to .odb. This will also allow you to control the conversion of buildings.

A general note, the size of the database could lead to high numerical requirements when running simulations, depending on the propagation model you will use. This is an important thing to account for when you have this big of an urban database.
