No, and I haven't thought of a good way to handle it. If you have an algori

Can you elaborate on how having "inner" and "outer" roles helps one

So, this does assume that it started as a valid OSM multipolygon, if
it fails that requirement I think we're better of fixing it in OSM
than coding around

There has actually been a python script to generate a simple sqlite database
form osm xml for years, but transforming the data into lines and polygons
really is the hard part.

Neither the GOES C api and SpatialLite have a version of BuildArea
so most of the code is devoted to assembling multipolygons, so
that's the area it's most likely to produce differe
I know this has been discussed here before, so it's seemed like the right place

I have a beta version of an osm2spatialite script written in python. Right now
it's only handles osm xml files, but there should be a pbf version in the
future. Ram is an issue so I'm not sure python is th
