Description

Written in Scala, GeoMesa is capable of ingesting, indexing, and querying billions of geometry features using a highly parallelized index scheme. GeoMesa builds on top of open source geo (OSG) libraries. It implements the GeoTools DataStore interface providing standardized access to feature collections as well as implementing a GeoServer plugin. Google announced that GeoMesa supported the Google Cloud Bigtable hosted NoSQL service in their release blog post in May 2015. GeoMesa also supports Bigtable-derivative implementations Apache Accumulo and
