The requirements for efficient access and management of massive multi-dimensional spatio-
temporal data in geographical information system and its applications are well recognized …

Compression techniques are essential for those applications which require more disk
accesses. Since the uncompressed data need more disk accesses than the compressed …

In this paper, we propose QMBRi, the inverse representation of the quantized minimum
bounding rectangles (MBRs) scheme, which compresses a minimum bounding rectangle …

With growing interest in location-based service (LBS), there is increasing necessity for
nearest neighbor (NN) search through query while the user is moving. NN search in such a …

본 논문은 주변탐색 (Surrounder Search: SuSe) 이라는 새로운 공간질의 방법을 제안한다. 이
기법은 현재 사용자의 위치를 중심으로 주변에서 가까운 관심영역의 공간객체를 탐색하는 …

In this paper, a new method of spatial query, which is called Surround Search (SuSe) is
suggested. This method makes it possible to search for the closest spatial object of interest …

Recent technological advances in location aware, mobile and wireless devices have
promoted the demand for efficient indexing structures for retrieval of information from moving …

위치기반 서비스 (LBS, Location Based Services) 에 대한 관심이 증가함에 따라 사용자가 이동
중에도 질의를 통한 최근접 이웃 (NN, Nearest Neighbor) 탐색에 대한 필요성이 증가하였다 …

This paper proposes SBR (Shrinking Bounding Rectangle based on Grid), a spatial object
compression method that can search for the location of players and objects present in a …
