postgis - 2.5.1+dfsg-1 main

PostGIS adds support for geographic objects to the PostgreSQL
object-relational database. In effect, PostGIS "spatially enables"
the PostgreSQL server, allowing it to be used as a backend spatial
database for geographic information systems (GIS), much like ESRI's
SDE or Oracle's Spatial extension. PostGIS follows the OpenGIS
"Simple Features Specification for SQL".
.
This package contains the PostGIS userland binaries for importing and
exporting shape and raster files: pgsql2shp, raster2pgsql, and shp2pgsql.
