Data - the gold on the IoT
A milestone on the way to Smart City
"Data is the gold on the Internet of Things," says Dr. Thomas Usländer. And gold has to be mined. This is exactly what the expert for sensor data does. Smart Cities only work with data, at SMART CITY SOLUTIONS part of INTERGEO (17 - 19 September 2019, Stuttgart) Fraunhofer IOSB wants to show what's possible - as a conference partner. The platform is a possible milestone for Usländer, on 18 September sensor data and data management will be the focus in Stuttgart.

Why are sensor data so important for smart cities?
Only those who have data can build a Smart City service on it - data about the environment and traffic, about residents and houses, about energy consumption for example. In cities, we have many sensors that deliver data. They don't always have to be measuring devices: Citizens can also contribute information, information from social networks can be sensor data. But sensor data must be processed in order to draw reliable conclusions. And this is often still lacking.
Why do many cities draw too few conclusions from sensor data?
It is often a question of cost and data reliability. Preparing the data is an enormous information technology effort. For example, because data is currently still available in a wide variety of formats. Cities often shy away from this effort and use only a few sensor data. This can be problematic, as can be seen from the current discussion about particulate matter measurement sites. We have known for a long time that reliable statements are only possible if we collect a lot of data. One example of this is traffic apps for smartphones, which can forecast traffic much better than looking at individual measuring points.
How can the solution look like?
Our goal at Fraunhofer IOSB is to increase efficiency through international standards. We have developed open source software: FROST® - Fraunhofer Open Source SensorThings API Server. FROST® implements the international standard "SensorThings API" of the Open Geospatial Consortium (OGC). It makes it possible not only to exchange sensor data, but also to combine and evaluate them more easily. The software can be used free of charge and we want to present it to cities and municipalities. The SMART CITY SOLUTIONS can become a milestone for us, especially because of its connection to the geodesy fair INTERGEO. We want to enlarge the community there, create (professional) public, reach demand and decision makers as well as financiers. We want to advance the topic, because even small and medium-sized cities with a smaller budget want and need to become smart! For citizens and industry alike. Smart City is also an immense location factor.
There is a lack of concepts and strategies for most German cities to become a Smart City.
