Geospatial indexing and analysis in Accumulo
GeoWave was developed at the National Geospatial-Intelligence Agency (NGA)
We are releasing this software under the Apache 2.0 license to increase the impact of government investments by providing developers with the opportunity to take things in new directions.
GeoWave is a library for storage, index, and search of multi-dimensional data on top of a sorted key-value datastore. GeoWave includes specific tailored implementations that have advanced support for OGC spatial types (up to 3 dimensions), and both bounded and unbounded temporal values.
GeoWave is intended to be a multidimensional indexing layer that can be added on top of any sorted key-value store.
It is expected that the out of the box functionality should satisfy 90% of use cases – at least that is the intent – but the modular architecture allows for easy feature extension as well as integration into other platforms.
GeoWave also targets keeping data configuration, format, and other information needed to manipulate data in the database itself. This allows software to programmatically interrogate all the data stored in a single or set of GeoWave instances without needing bits of configuration from clients, application servers, or other external stores.
