Summarizing GPS trajectories by salient patterns
نویسندگان
چکیده
Individuals can easily record their movements in space nowadays with personal navigation devices based on the GPS technology. The recorded data contain in principle detailed information about a traveled route. The information inherent in the data could be used to automatically generate travel diaries. In this paper we study a method to summarize and to symbolize a route according to the cardinal and egocentric directions traveled. The same symbolization method can be applied to other parameters of tracking data, e.g. speed.

GPS Jamming Detection in UAV Navigation Using Visual Odometry and HOD Trajectory Descriptor
Auto-navigating of unmanned aerial vehicles (UAV) in the outdoor environment is performed by using the Global positioning system (GPS) receiver. The power of the GPS signal on the earth surface is very low. This can affect the performance of GPS receivers in the environments contaminated with the other source of radio frequency interference (RFI). GPS jamming and spoofing are the most serious a...

The Unmanned Aerial Vehicles (UAV) positioning in the outdoor environment is usually done by the Global Positioning System (GPS). Due to the low power of the GPS signal at the earth surface, its performance disrupted in the contaminated environments with the jamming attacks. The UAV positioning and its accuracy using GPS will be degraded in the jamming attacks. A positioning error about tens of...
متن کاملClustering User Trajectories to Find Patterns for Social Interaction Applications
Sharing of user data has substantially increased over the past few years facilitated by sophisticated Web and mobile applications, including social networks. For instance, users can easily register their trajectories over time based on their daily trips captured with GPS receivers as well as share and relate them with trajectories of other users. Analyzing user trajectories over time can reveal...
متن کاملDetecting Anomalous Trajectories and Behavior Patterns Using Hierarchical Clustering from Taxi GPS Data
Anomalous taxi trajectories are those chosen by a small number of drivers that are different from the regular choices of other drivers. These anomalous driving trajectories provide us an opportunity to extract driver or passenger behaviors and monitor adverse urban traffic events. Because various trajectory clustering methods have previously proven to be an effective means to analyze similariti...
متن کاملMoving Objects Trajectories’ Meta Model
This paper presents a repository of trajectories’ models in a proposed moving object trajectories’ meta-model. It is highly abstracted and unified schema where current trajectories’ models are integrated; new patterns are added, such as measure and observation according to OGC sensor and measure meta-model. Furthermore, it integrates activity concept and generic device used as mobile object det...
