The City of Zwolle, Netherlands, recognizes that they will likely face challenges resulting from climate change, and they are undertaking efforts to improve their ability to adapt to changes as they occur. In order to understand those changes, they must first be able to monitor them, and so the city established a sensor network to track weather and air quality, connecting this sensor network to the ArcGIS platform. To gain support from citizens, the city is using ArcGIS Hub to publicize and provide information about the project, leading to greater citizen involvement. Learn how citizens in Zwolle are developing their own inexpensive groundwater monitoring devices, connecting this all to the Hub.
