ST-Hadoop is an open-source MapReduce extension of Hadoop designed specially to work with spatio-temporal data. ST-Hadoop injects the spatiotemporal awareness inside the base-code of SpatialHadoop to allow querying and analyzing huge datasets on a cluster of machines. The spatio-temporal indexing techniques inside ST-Hadoop primarily tuned to provide the accommodation of new updated dataset efficiently without the need to rebuild its index. It organizes data in dynamic hierarchical index structure to gain fast performance in its batch processing.
