How to import OSM Data into mongoDB in easy way

MongoDB is not the database of choice for typical OSM operations so you are unlikely to find any tried and tested howtos beyond what any major search engine will give you if you type in "openstreetmap mongodb", namely http://derickrethans.nl/importing-osm-into-mongodb.html

It mostly depends on what you want to do with the data. You can always parse the data yourself and import it that way. How you store data depends greatly on what you want to do with it.

For rendering maps (a common OSM usage), you need geographic indexes, for doing spatial analysis, you need geographic functions (what's the distance between X and this road), if these things are not in MongoDB, then you will not be able to easily use OSM data in MongoDB.

This can be done using the mongosm importer.

1. Download the osm file: http://download.geofabrik.de/europe/germany/baden-wuerttemberg/karlsruhe-regbez-latest.osm.bz2.
2. Extract the file. Try f.ex. 7zip, or bunzip2 karlsruhe-regbez-latest.osm.bz2 in a shell.
3. Download the repo. Either from me (patched), or from the original and replace Connection with MongoClient.
4. python mongosm-master/insert_osm_data.py karlsruhe-regbez-latest.osm imports the data.
