    <abstract>
      <para>PostGIS is an extension to the <link xlink:href="https://www.postgresql.org/">PostgreSQL</link> object-relational
      database system which allows GIS (Geographic Information Systems)
      objects to be stored in the database. PostGIS includes support for
      GiST-based R-Tree spatial indexes, and functions for analysis and
      processing of GIS objects.</para>
