Transportation networks and associated analytic algorithms have been extensively studied in the research domain, with numerous systems in widespread production. An equally important domain that has not been well addressed by the research community are network models used to support the utility domain (e.g., water, wastewater, stormwater, gas, electric, pipeline, ...

Caching is a well-known approach to achieve good performance and scalability in mobile computing environments. Using this technique, the query response time and the overall system performance can be extremely improved by decreasing the volume of data transferred between the server and the mobile device. However, the effectiveness of caching ...

Network data models are frequently used as a mechanism to describe the connectivity between spatial features in GIS applications. Real-life network models are dynamic in nature since spatial features can be periodically modified to reflect changes in the real world objects that they model. Such updates may change the connectivity ...

We describe the FlexTrack system for querying trajectories using flexible pattern queries. Such queries are composed of a sequence of simple spatio-temporal predicates, e.g., range and nearest-neighbors, as well as complex motion pattern predicates, e.g., predicates that contain variables and constraints. Users can interactively select spatio-temporal predicates to construct such ...

Call Detail Record (CDR) databases contain many millions of records with information about mobile phone calls, including the users' location when the call was made/received. This huge amount of spatio-temporal data opens the door for the study of human trajectories on a large scale without the bias that other sources, ...

The wide adaptation of GPS and cellular technologies has created many applications that collect and maintain large repositories of data in the form of trajectories. Previous work on querying/analyzing trajectorial data typically falls into methods that either address spatial range and NN queries, or, similarity based queries. Nevertheless, trajectories are ...

With the recent advancements and wide usage of location detection devices, large quantities of data are collected by GPS and cellular technologies in the form of trajectories. While most previous work on trajectory-based queries has concentrated on traditional range, nearest-neighbor and similarity queries, there is an increasing interest in queries ...

The standard database mechanisms for concurrency control, which include transactions and locking protocols, do not provide the support needed for updating complex geographic data in a multiuser environment. The preferred method to resolve conflicts in GIS systems is to encapsulate the modifications generated by the end users through the use ...

Network data models are widely used to describe the connectivity between spatial features in GIS architectures. Recent applications demand that such models are editable in multiuser environments. The preferred method to resolve conflicts in GIS systems is the use of multiple versions of the data to encapsulate the modifications generated ...

Network data models are frequently used as a mechanism to describe the connectivity between spatial features in many existing and emerging GIS applications (location-based services, transportation design, navigational systems, etc.). Connectivity information is required for solving a wide range of location-based queries like finding the shortest path, service areas discovery, ...

We introduce a novel query type defined over streaming moving object data, namely, the Continuous Motion Pattern (CMP) Queries. A motion pattern is defined as a sequence of distinct spatial predicates, each attached to a temporal constraint. The spatial predicates can be of various types (range, nearest neighbor, etc.) The ...

Given the plethora of GPS and location-based services, que- ries over trajectories have recently received much attention. In this paper we examine trajectory joins over streaming spatiotemporal data. Given a stream of spatiotemporal trajectories created by monitored moving objects, the outcome of a <em>Continuous Spatiotemporal Trajectory Join</em>(CSTJ) query is the ...

The increasing popularity of the GPS technology and the growing amount of highly accurate trajectory data it generates have created the need for developing applications that efficiently store and query trajectories of moving objects. Traditional relational database management systems, however, are not well equipped to handle this novel and complex ...

Publish-subscribe applications are an important class of content-based dissemination systems where the message transmission is defined by the message content, rather than its destination IP address. With the increasing use of XML as the standard format on many Internet-based applications, XML aware pub-sub applications become necessary. In such systems, the ...

Many spatiotemporal applications store moving object data in the form of trajectories. Various recent works have addressed interesting queries on trajectorial data, mainly focusing on range queries and Nearest Neighbor queries. Here we examine another interesting query, the Time Relaxed Spatiotemporal Trajectory Join (TRSTJ) which effectively finds groups of moving ...

This paper introduces a novel type of query, what we name Spatio-temporal Pattern Queries (STP). Such a query specifies a spatiotemporal pattern as a sequence of distinct spatial predicates where the predicate temporal ordering (exact or relative) matters. STP queries can use various types of spatial predicates (range search, nearest ...

Efficiently and accurately discovering similarities among moving object trajectories is a difficult problem that appears in many spatiotemporal applications. In this paper we consider how to efficiently evaluate trajectory joins, i.e., how to identify all pairs of similar trajectories between two datasets. Our approach represents an object trajectory as a ...
