The MobilityDB Development Team is pleased to announce MobilityDB version 1.0 beta1.
MobilityDB is an open-source extension that adds support for temporal and spatiotemporal objects to PostgreSQL and its spatial extension PostGIS. Its main use is to store and query GPS trajectories and other mobility and 2D/3D location time series. More information about the use of MobilityDB can be found in the tutorials included in the manual and the workshop (see links below).
MobilityDB features:
* Spatiotemporal types tgeompoint and tgeogpoint, which are based on the geometry and geography types provided by PostGIS (restricted to 2D or 3D points) and are used to represent points that evolve on time.
* Temporal types tbool, tint, tfloat, and ttext which are based on the bool, int, float, and text types provided by PostgreSQL and are used to represent basic types that evolve on time.
* Extensive operations for manipulating the new types: ETL, spatiotemporal joins, interaction with space and time, time-varying predicates, temporal aggregations, etc.
* GiST and SP-GiST indexes to support the new types.
* Type analyze and selectivity estimation for the new types and operations. These are used by the PostgreSQL planner to select the most efficient execution plan for queries.
* Scalability through integration with Citus (
https://www.citusdata.com/).
* MobilityDB follows the Moving Features specification (
https://www.opengeospatial.org/standards/movingfeatures) from the Open Geospatial Consortium (OGC).
* Associated docker image (
https://hub.docker.com/r/codewit/mobilitydb)
* Associated Python driver (

MobilityDB is the only moving object database that implements the full SQL standard. It is available under the open-source PostgreSQL license (
https://www.postgresql.org/about/licence/). More information about MobilityDB can be found in our talks at various conferences which are available at the project home page.
MobilityDB is developed by the Computer & Decision Engineering Department of the Universite libre de Bruxelles (ULB) under the direction of Prof. Esteban Zimanyi.
