POIs are user-defined network objects which are of special interest, like car parks or schools. You can use POIs to display facilities with special usage, for data management, or for reachability analyses, for example.
POIs have a spatial reference and are managed in categories which you can define. Therefore, you must create at least one POI category if you want to create a POI (Creating a POI category).
POIs are fixed in the coordinate system. Furthermore, they can have a surface, for example, to display an industrial area. POIs can also be linear, for example, to display the course of a river. However, you cannot insert linear POIs manually. You can import linear POIs with the network file or a shapefile.
