GeoWave Geospatial indexing and analysis in accumulo
GeoWave is an open source set of software that:
- Adds multi-dimensional indexing capability to Apache Accumulo
- Adds support for geographic objects and geospatial operators to Apache Accumulo
- Contains a GeoServer plugin to allow geospatial data in Accumulo to be shared and visualized via OGC standard services
- Provides Map-Reduce input and output formats for distributed processing and analysis of geospatial data
Basically, GeoWave attempts to do for Accumulo as PostGIS does for PostgreSQL.
GeoWave was developed at the National Geospatial-Intelligence Agency (NGA) in collaboration with RadiantBlue Technologies and Booz Allen Hamilton. The government has “unlimited rights” and is releasing this software to increase the impact of government investments by providing developers with the opportunity to take things in new directions. The software use, modification, and distribution rights are stipulated within the Apache 2.0 license.
All pull request contributions to this project will be released under the Apache 2.0 license.
Software source code previously released under an open source license and then modified by NGA staff is considered a “joint work” (see 17 USC 101); it is partially copyrighted, partially public domain, and as a whole is protected by the copyrights of the non-government authors and must be released according to the terms of the original open source license.
