Abstract. In this paper we present a design concept, architecture and implementation of a microservice to process and integrate rain information into a car navigation system in the form of rain map features. Two different input data sources are considered: QuadTile JSON format and GeoTIFF images. Our system converts this input data into an ouput GeoJSON format with only the most relevant information for the map overlay system in the navigation system of the car. We discuss different options for the cloud appearance, like color, shape and transparency. We present our microservices architecture together with data pipelines and implementation. Our approach allows for low latency and spare computing resources, which are especially needed in embedded systems. Finally, we discuss the advantages and disadvantages of our approach as well as further work.
