Yes, but is it really? It's a storage format, you need a 3rd party driver to
read it and it's optimized for querying, not for storing high volume of data
in an efficient manner. And it's a database without a standard schema.
I see spatialite as a good way for thick clients to store geo data without
the need for an extra DB installation, but not as a good way to exchange
data files (as opposed to osm.pbf, for example).
Or am I missing something here? I'm interested to know because I plan to add
spatialite support in Maperitive.
