node app.js

http://localhost:3000/import in your browser will import municipalities from municiopios_con_actividad_narcoparamilitar_2013.json to the municipalities collection in mongodb

http://localhost:3000/enrich in your browser will call OSM Nominatim API for each municipalities in mongo and retrieve the exact place location + boundary of that town in GeoJSON format, and then save it back to mongo

http://localhost:3000/merge in your browser will merge the group-specific data (filenames for each groups are defined import/groups.json) with the existing municipalities imported previously

http://localhost:3000/api/municipality will show all the municipalities and their associated data (groups, location, etc..), basically an output of the data in mongodb

http://localhost:3000/api/municipality POST QUERY - To manually create a municipality in MongoDb.

http://localhost:3000/api/municipality/:slug will show one municipality. The slug is the url-friendly name associated to each municpality.

http://localhost:3000/api/municipality/boundary will export all the municipalities, location and group data to a format that can be used by a visualization. The geojson location data is converted to topojson to save on file size.

http://localhost:3000/api/municipality/boundary?savetodisk=true will export the previous query to a JSON file, to allow a visualization to use this file instead of querying the API.

http://localhost:3000 will show the visualization in your browser
