> geometry. In addition, bindings for the MEOS library in other programming
> languages are available, in particular for Java with JMEOS, for C# with
> MEOS.NET and for SparkSQL.

> environments regardless of PostgreSQL. These are template types, which
> means that they are containers of other types, in a similar way as lists
> and arrays contains values of other types. Furthermore, a new template data
> type set was also added. Therefore, the types timestampset, period, and
> periodset in version 1.0 are replaced by the types tstzset, tstzspan, and
> tstzspanset in version 1.1. Finally, the API of MEOS and MobilityDB was
> streamlined to improve usability and to facilitate the other bindings that
