MOBILITYDB

MobilityDB provides two main geospatial trajectory type: tgeompoint for a temporal geometry point, and tgeogpoint for a temporal geography point. Both can represent a geospatial point that moves over time, where the coordinates are respectively expressed as PostGIS geometry or geography. It also provides a rich set of functions to manage these type; including: input/output, topological relationships, speed, direction, distance, etc... Location tracking devices, such as GPS, are nowadays widely used in smartphones, and in vehicles. As a result, geospatial trajectory data are currently being collected and used in many application domains. MobilityDB provides the necessary database support for storing and querying such geospatial trajectory data
