Hello,
when it comes to read raw OSM dumps it's quite straightforward to parse nodes: their geometry properties can be read alongside with their tags. When it comes to linestrings and relations it is more complicated to access their geometry: the geometry of referenced nodes needs to be combined into lines and polygons. Also one needs to decide which linestrings/relations are actually lines and which are areas.
I know how this can be done but I am wondering if there are preprocessed datasets around that have geometries already precomputed. That would make sense to me as a lot of people face the sample problem and this step is quite resource intense.
A huge file containing all osm items as geojson would be my dreamcase. Does this exist?
Thank you for your time and your help!
