## Docker Imposm

This image will take care of doing the initial load for the selected region 
(e.g. planet, or a country such as Malawi) into your database. It will then
apply at a regulart interval (default is 2 minutes) any diff that arrives
in the /home/import_queue folder to the postgis OSM database. The diffs
are fetched by a separate container (see osm_update container).

The container will look for an OSM file (*.pbf) and its state file 
(*.state.txt) in BASE_PBF.

With -e, you can add some settings :
 - TIME = 120, seconds between 2 executions of the script
 - USER = docker, default user
 - PASSWORD = docker, default password
 - HOST = db
 - PORT = 5432
 - SETTINGS = settings, folder for settings (with *.json and *.sql)
 - CACHE = cache, folder for caching
 - BASE_PBF = base_pbf, folder the OSM file
 - IMPORT_DONE = import_done, folder for diff which has been imported
 - IMPORT_QUEUE = import_queue, folder for diff which hasn't been imported yet
 - SRID = 4326, it can be 3857
