StadtRAD stations Hamburg

The data set contains the position of all StadtRAD stations in the Hamburg city area and the number of bicycles and load pedals currently available for rental. More information about the real-time service: The real-time data service contains the position of all StadtRAD stations in the Hamburg city area and the number of bicycles and load pedals currently available for rental in JSON format provided in the SensorThings API (STA). In the SensorThings API (STA), the entity "Thing" stands for one StadtRad station at a time. For the number of available wheels and the load pedals, there is one entity "Datastream" for each "Thing". The number of available wheels (real-time data) is obtained via the entity "Observations". All times are given in Coordinated Universal Time (UTC). In the Datastreams entity, there are additional key-value pairs under the "key" "properties" in the JSON object. Following the service and layer structure in GIS, we have introduced service and layer as additional "key-value pairs" under the JSON property. { "properties":{ "serviceName": "HH_STA_StadtRad", "layerName": "E-carrier", "key":"value"} } Available layers in the layerName are: * E-load bicycle * Bicycles 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 'HH_STA_StadtRad' and properties/layerName eq 'E-Lastenraeder' The real-time data can also be obtained through an MQTT broker. The necessary IDs 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
