Geographical divisions (GD) being administrative, parcel or census divisions frequently change over time. When such changes are not well documented, they introduce biases in the understanding of the evolution of such a given area. To cope with this problem, we have designed a Knowledge Graph (KG) that allows for the description of many GDs in the world and the changes they undergone over time. In this demo, we present a Web application called GeoChange-Viz that connects to this KG and provides spatial planners with an innovative tool for geovisualizing and understanding territorial changes over time.
