15. A computer-readable storage medium comprising instructions that, when executed by at least one processor, causes the at least one processor to perform acts comprising: responsive to receiving a search query pertaining to at least one of an entity or activity of interest in a scene, performing a search over a geospatial temporal semantic (GTS) graph for the at least one of the entity or activity in the scene, wherein the GTS graph comprises: nodes that represent objects captured in at least one of remote sensing data corresponding to the scene or a geolocation dataset, the nodes comprising a first node representing a first object, the first node assigned data that indicates that the first node corresponds to a trajectory, the trajectory comprising locations of the first object over a window of time; and undirected edges, wherein each undirected edge in the undirected edges couples a respective pair of nodes in the nodes, the undirected edge assigned data that is indicative of a symmetric relationship between objects in the scene represented by nodes in the pair of nodes; identifying a location of the at least one of the entity or activity in the scene based upon the search of the GTS graph; and outputting graphical data to a display indicating the location of the at least one of the entity or activity in the scene.
17. The computer-readable storage medium of claim 15 , wherein identifying the location of the at least one of the entity or activity in the scene comprises identifying match locations in the locations of the first object, the match locations matching parameters of the search query.
