Geowave is a library used to store, index and analyze geospatial data on top of Accumulo which is a free software implementation of Google’s Big Table. Accumulo in turn makes use of Zookeeper to handle distributed synchronization and uses Hadoop FileSystem for distributed and scalable storage of the data. Geowave decomposes multi-dimensional data to single dimensional data using a transformation called as Space Filling Curves. GeoServer is a java based server which provides a platform to view and edit geospatial data. Hence at an abstract level, we can summarize that the data which is transformed by goewave and stored(ingested) in Accumulo can be extracted and viewed from geoserver.
Following article will explain how we can setup the system to have Geowave and Geoserver working with Accumulo for a development environment.
