[Seminar] SpatialHadoop: A MapReduce Framework for Spatial Data
◾호스트: 문봉기 교수(x1842, 02-880-1842)
This talk is about SpatialHadoop; a full-fledged MapReduce framework with native support for spatial data. SpatialHadoop is a comprehensive extension to Hadoop that injects spatial data awareness in each Hadoop layer, namely, the language, storage, MapReduce, and operations layers. In the language layer, SpatialHadoop adds a simple and expressive high level language for spatial data types and operations. In the storage layer, SpatialHadoop adapts traditional spatial index structures, Grid, R-tree and R+-tree, to form a two-level spatial index. SpatialHadoop enriches the MapReduce layer by new components for efficient and scalable spatial data processing. In the operations layer, SpatialHadoop is already equipped with three basic operations, range query, kNN, and spatial join as case studies. Other spatial operations can also be added following a similar approach. The talk will also discuss various active projects for big spatial data that take advantage of SpatialHadoop.
