My company uses geometry ( the_geom ) data type for storing geospatial data. I' ve recently been acquainted to the concept of geography ( the_geog ) data type

You might already know about the basic geometry types in PostGIS: points, lines (called “ linestrings ” in PostGIS lingo), and polygons in a few different forms. An overview of t hese PostGIS geometries is provided in the following picture: In addition to these basic geometry structures, there is also the Post GIS geometry_dump structure.

The basis for the PostGIS geometry data type is a plane.

GEOMETRY and GEOGRAPHY are different PostgreSQL TYPES; exposed as higher level (SQL), user-defined composite types to the psql environment, but implemented as lower level (C) base types. These base types are defined on the C level with e.g. their own typemod constraints, TOAST support, data I/O functions, operator classes and casting behaviour.

I' ve recently been acquainted to the concept of geography ( the_geog ) data type processing. In this tutorial, I will go through some of the different types of geometries… A beginners walkthrough in PostGIS Geometry types and functions.

Once the event subscriber is registered, you can use the column types geometry and geography in your property mappings (please read the PostGIS docs to understand the difference between these two types).

I så fall får du gärna skicka den Returns the type of the geometry as a string. Eg: 'LINESTRING', 'POLYGON', 'MULTIPOINT', etc. OGC SPEC s2.1.1.1 - Returns the name of the instantiable subtype of Geometry of which this Geometry instance is a member. The name of the instantiable subtype of Geometry is returned as a string. The WKT strings we’ve see so far have been of type ‘text’ and we have been converting them to type ‘geometry’ using PostGIS functions like ST_GeomFromText().
