An experimental spatial information system
… features on a map is complicated by the spatial properties not found in typical alphanumeric data. We have designed an entity-oriented relational system for representing the cartographic data, using the concept of spatial data structures. Each geographic entity such as a region, road, or …

Scalable Techniques for Trajectory Outlier Detection
… have led to an increased availability of spatial data describing the movement of objects such as vehicles, animals, etc. Such data is obtained by recording the positions of the objects at regular intervals and then arranging the collected positions of each object into a time-ordered …

Spatial and Temporal Topological Analysis of Landscape Structure using Graph Theory
… of a landscape. Traditional approaches to spatial analysis mainly entail the use of spatial statistics and classical spatial data structures to analyse the composition of a landscape. However, such analyses are unable to capture the essence of landscape configuration because spatial …

Multicore construction of k-d trees with applications in graphics and vision
The k-d tree is widely used in graphics and vision applications for accelerating retrieval from large sets of geometric entities in R^k. Despite speeding up an otherwise brute force search, the time to construct and traverse the k-d tree remain a bottleneck in many applications. Increasing …
