To use the PostGIS geometry or geography type, install PostGIS on the PostgreSQL database cluster. Once installed, either use the PostGIS template database to create a database containing the PostGIS types, or configure an existing database to use the PostGIS types. See PostGIS documentation You can specify a keyword to use the PostGIS geometry type when you create feature classes in ArcGIS. You can also use SQL to create spatial tables with PostGIS columns, then access them from ArcGIS or register them with the geodatabase. Geometry data types. As indicated in the table, ArcGIS creates and can work with three spatial data types in PostgreSQL: Esri ST_Geometry, PostGIS geometry, and PostGIS geography.

PostGIS has two spatial type options: geometry and geography. Only the geometry type is supported with ArcGIS. When you use the PostGIS geometry storage type with ArcGIS, keep the following rules in mind: It uses the OGC well-known binary (WKB) and well-known text (WKT) representations of geometry.

wkb_geometry geometry (Geometry,27700) PostGIS stores a table’s spatial information in geometry columns. Usually these columns have the word “geom” floating around in their name. If you select * on a table with a geometry column, the If the Postgis-Extension is loaded, then your SQL perhaps does not find the geometry-type because of missing search-path to the public schema. Try. SET search_path = , public; in the first line of your scsript. (replace with the other required search-paths) Share. Improve this answer.

I'm faced with the following problem. I have to migrate from Oracle database to PostgreSQL+PostGIS.

PostGIS has two spatial type options: geometry and geography.

The ST_Geometry spatial data type can be used in PostgreSQL databases that contain a geodatabase and those that do not. The ST_Geometry data type allows you to integrate spatial data with other types of business data, so your multiuser database gains the advantage of adding a geographic component to your analyses and data products. I want to comparate MULTILINESTRING geometry type with POINT geometry type. In order to test if an (XY) from MULTILINESTRING match with an (XY) from POINT.
