Geospatial-temporal semantic graph representations of trajectories from remote sensing and geolocation data
| DWPI Title: Computing device for facilitating analysis of trajectory features of interest in datasets, has processor for providing geospatial temporal semantic graph to search system, where graph is searchable in response to receipt of query |
| Abstract: Various technologies for facilitating analysis of large remote sensing and geolocation datasets to identify features of interest are described herein. A search query can be submitted to a computing system that executes searches over a geospatial temporal semantic (GTS) graph to identify features of interest. The GTS graph comprises nodes corresponding to objects described in the remote sensing and geolocation datasets, and edges that indicate geospatial or temporal relationships between pairs of nodes in the nodes. Trajectory information is encoded in the GTS graph by the inclusion of movable nodes to facilitate searches for features of interest in the datasets relative to moving objects such as vehicles. |
| Use: Computing device for facilitating analysis of trajectory features of interest in large remote sensing and geolocation datasets for aircraft and spacecraft-based surveillance and imaging systems. Uses include but are not limited to buildings, roads, body of water, vehicles and events of interest. |
| Advantage: The device infers additional locations of the object corresponding to a movable node, while calculating distances for purpose of computing distance edges. |
| Novelty: The device has a processor for performing acts comprising geolocation data indicative of a set of locations of a first object over a window of time based upon a remote sensing image of a scene and the geolocation data. The processor constructs a geospatial temporal semantic (GTS) graph that is representative of the objects in the scene, where the GTS graph comprises nodes that represent the object and a first node in the nodes represents the first object. The processor provides the GTS graph to a search system, where the GTS graph is searchable in response to receipt of a query. |
