“…In conventional approaches, the location information of moving objects were expressed as a geometric coordinate (x,y) in two-dimensional space. However, instead, [1] propose to express location information using both hierarchical administrative district and road network in one-dimensional space that fits real world better. For instance, if a moving object is in a building at a coordinate of latitude = 125.58 and longitude = -37.34, then it can be expressed as a set of fields according to an administrative district such as city, road-name, road-block (e.g., Seoul, Main road, 165th block).…”

“…As in the paper [1] here also we assume that the database stores the complete history of moving objects through time and must answer queries about any time in the history of objects. We assume that each database record has the format (oid, location, time), where oid identifies an object, location is the spatial coordinates(x,y) represented as binary string, and time indicates the time in which the object remained at position (x,y).…”

Abstract. Spatio-Temporal data analysis plays a central role in many securityrelated applications including those relevant to transportation infrastructure, border and inland security. In several applications, data objects move on predefined spatial networks such as road segments, railways, and invisible air routes, which provides the possibility of representing the data in reduced dimension. This dimensionality reduction gives additional advantages in spatiotemporal data management like indexing, query processing, similarity and clustering of trajectory data etc. There are many proposals concerning trajectory similarity problem which includes Euclidian, network, time based measures and concepts known as Position of Interest(POI), Time of Interest(TOI) etc. This paper demonstrates how these POI and TOI methods could be advantages in security informatics domain suitable to work with road network constrained moving object data, stored using a binary encoding scheme proposed in a previous PAISI paper.
