City bike stations Hamburg

The data set contains the position of all StadtRAD stations in the Hamburg city area and the number of currently available bicycles and load pedals.

For 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 currently available bicycles and load pedals in JSON format provided in the SensorThings API (STA). In the SensorThings API (STA) stands the entity “Things”; for each one city bike stations. For the number of available wheels and load pedals, there is one entity in each case. it’s worth noting;. The number of available wheels (real-time data) is obtained via the entity “Observations &.”

All times are given in the Coordinated World Time (UTC).

In the entity Datastreams, there are in the JSON object under the ‘key’; ‘Properties’; other “key-value pairs”quot;. Based on the service and layer structure in the GIS, we have service and layer as an additional ‘key-value pair’; introduced under the JSON object properties.

{
"properties":{
Service name: “HHSTAStadtRad"”,
&layerName" ‘E-Lastenraeder’;
“Quot;key""value"}
}

Available layers in the layerName are:
E-Lastenraeder
Turrets

With the help of this ‘key-value pair’; you can then define filters for the REST request, e.g.
https://iot.hamburg.de/v1.0/Datastreams?$filter=properties/serviceName eq 'HHSTA CityRad' and properties/layerName eq 'E-Lastenraeder'

The real-time data can also be obtained via an MQTT broker. The necessary IDs can be obtained via a REST request and then used for the subscription to a data stream:
