osm-ro-cities

This project contains poly files for cities in Romania and street names in json format extracted from openstreetmap data.

NOTE: All content extracted from openstreetmap data is copyright: © OpenStreetMap contributors

Steps to add more cities and streets to repository

1. Create the poly file

   • Go to http://nominatim.openstreetmap.org/ and search for the city you'd like added and select details and locate the OSM relation number (example OSM relation 8334767)
   • Go to http://polygons.openstreetmap.fr/ and use the relation id obtained from previous step
   • Download the poly and geoJSON files and place it in the correct folder with a correct name, example: cities/ms/targu-mures_marosvasarhely.poly Always use the "_" as the city name separator if city has name in Romanian and Hungarian.

2. Extract the openstreetmap data relevant to a city using osmosis command line:

osmosis --read-pbf romania-latest.osm.pbf file="romania-latest.osm.pbf" --bounding-polygon file="targu-mures_marosvasarhely.poly" --write-xml file="targu-mures_marosvasarhely.osm"

3. Use the provided java utility class see usage that will generate the street names for a city and place it in the correct folder: streets/ms/targu-mures_marosvasarhely.json

Steps to use the data in the repository

• You can use the geoJSON files, see: https://en.wikipedia.org/wiki/GeoJSON
• You can use the street json files to create street lookup functionality in your app

Future roadmap

• Check if POI (point of interests) data can be also extracted the same way.
