GeoWave: Distributed Geospatial Indexing

GeoWave is an open source software project that leverages the scalability of a distributed key-value store for effective storage, retrieval, and analysis of massive geospatial datasets. It currently does so by providing plugins to connect GeoTools, PDAL, and Mapnik to an Accumulo based data store, with an HBase data store soon to follow.
