The data set contains the locations of the publicly accessible charging facilities for electric vehicles in the Hamburg electromobility model region. The associated factual information such as number of charging points, plug types and access options are included. In addition, the operating status (free, occupied, out of service, no data) of the charging points is indicated in real time. Further information about the real-time service: The real-time data service contains the locations of the publicly accessible charging facilities for Electric vehicles in the Hamburg Electromobility Model Region provided in JSON format via the SensorThings API (STA). For the e-charging stations in the SensorThings API (STA), an object was created for each station in the “Thing” entity. created. For each loading point there is an object in the entity “Datastreams”. The real-time data on the status of the charging point is stored in the STA in the entity "Observations" published. All times are given in Coordinated Universal Time (UTC). In the Datastreams entity there is a JSON object under the "key" "properties" further "key-value pairs". Based on the service and layer structure in GIS, we have service and layer as additional "key-value pairs" introduced under the JSON object properties. { "properties":{ "serviceName": "HHSTAE-Charging Stations", "layerName": "Status_E-Charging Point", "key" ;:"value"} } With the help of these "key-value pairs" Filters can then be defined for the REST request, e.g. https://iot.hamburg.de/v1.0/Datastreams?$filter=properties/serviceName eq 'HHSTAE -Charging stations' and properties/layerName eq 'Status_E-Ladepunkt' The real-time data can also be obtained via an MQTT broker. The IDs required for this can be obtained via a REST request and then used for the subscription to a data stream: MQTT broker: iot.hamburg.de Topic: v1.0/Datastream({id} )/Observations
