chargingstations2geojson's Introduction

ChargingStations2GeoJson

Converts the Dataset of public EV charging stations in Luxembourg into a format (GeoJSON) that is more suited for importing in OpenStreetMap. This Dataset is provided by Chargy.lu and published under the Creative Commons Zero License on the Luxembourgish Data Platform.

The import process is documented on the OpenStreetMap Wiki Page.

⭐ This project has been featured as a best-practice re-use in the Luxembourg Factsheet published in the 2018 European Open Data Maturity Report!

Usage

Preparing the data

> python3 ChargingStations2GeoJson.py --help

usage: ChargingStations2GeoJson.py [-h] [-o [OUTFILE]] [-v] [-s] [INFILE]

Convert the Chargy KML Dataset into GeoJSON Points

positional arguments:
  INFILE                KML File from Chargy. If unset, the most recent file
                        will be pulled from the OpenData Portal

optional arguments:
  -h, --help            show this help message and exit
  -o [OUTFILE], --outfile [OUTFILE]
                        Overrides the default filename for the exported
                        GeoJSON file
  -v, --verbose         Overrides the default LogLevel
  -s, --strict          Enables strict mode. Halt execution if any unexpected
                        value is found.

chargingstations2geojson's Issues

Export to OSM XML

Currently only GeoJSON Export is supported.
It would be neat if the data could be exported as OSM XML.

A flag could be used to choose what format to export.

Set operational_status

Figure out what the field description describes, and what exactly the meaning of OFFLINE is.

Filter out existing charging stations

Currently all charging stations from the dataset are exported into the output file.
It would be nice to be able to filter out nodes that already exist in OSM and didn't change from the previous import.
