摘要：Discovering appropriate services with related geospatial datasets among a large number of available ones is a key task in the Geographic Information Science domain. This paper proposes a locality-aware peer-to-peer (P2P) based approach for geospatial web services discovery. We present a locality-aware hybrid P2P sy stem for geospatial web service discovery, based on spatial hash index to preserve spatial locality information while retaining local balancing properties of underlay networks
