Summary

In this chapter, we covered geofencing concepts and what geofencing is and presented different use cases and applications of geofencing. We touched upon and revisited geometry operations, especially LineString and polygons. To illustrate a simple application of geofencing, we first covered masking with points in polygon topology operations. Once we mastered these geometry and topology concepts, we moved on to using geofencing in real-world application data. Putting all of these different pieces together, we were able to construct a mask for the whole trajectory data with three geofencing polygons: an airport, beach, and city center. Finally, we animated the trajectory points, where trajectory points move and indicate whether the point is inside the geofence polygon or outside. The applications of geofencing are limitless and can be applied in different case scenarios and...
