Evaluating Geospatial Geometry and Proximity Queries Using Distributed Hash Tables
Matthew Malensek, Sangmi Lee Pallickara, Shrideep Pallickara · Computing in Science & Engineering · 2014
This article explores the challenges associated with supporting geospatial retrievals constrained by arbitrary geometric bounds, geographic proximity, and relevance rankings. The authors' proposed solution involves the use of a lightweight, distributed spatial indexing structure, the geoavailability grid. The index can also be used in nondistributed settings, and performs competitively with other spatial indexing technologies.
