Key Information

• This data store uses the PostgreSQL JDBC driver to connect to the database.

• The data store will not create missing database objects such as tables and views. Ensure these are created before trying to write data.

• For 1Integrate to read the dimensionality of a geometry, you must set the geometry column type in your PostGIS database. If the geometry column type is not set specifically, 1Integrate will read XY data only, and the 3rd ordinate will be lost.

  Example: Instead of using "geometry", use "geometry(LineStringZ)" for heighted lines.

Input and Output Parameters

Input Parameters

Parameter	Description
URL	The full JDBC connection string for connecting to the PostgreSQL/PostGIS database. Example:   jdbc:postgresql://<host>:<port>/<database>
Username	The username for your PostgreSQL/PostGIS database.
Password	The password for your PostgreSQL/PostGIS database.
Schema	The schema to read tables from. Leaving this blank will result in all available schemas being read from while tables in the non-default schema are qualified with their schema. Note: The schema value is case sensitive
PostGIS Schema	The schema PostGIS was installed on, defaults to public.
Coordinate Reference System	This parameter can be used to specify a Coordinate Reference System (CRS) code of the input data, if it cannot be deduced automatically. This will not re-project the data, but allows its current CRS to be defined (e.g to enable multiple data stores to open where one does not have a CRS defined). Note: Coordinate Reference System parameters are required in a session that will write data to Oracle. See Coordinate Reference System for more information on when this is required.
Allow Invalid Geometries	Allows features with invalid geometries (e.g. duplicate vertices, self-intersections) to be imported. This is necessary if they need to be imported in order to be validated or corrected. If not ticked then features with invalid geometries are not imported and are logged as feature errors in the open data task.
Fix ring direction and inclusion errors	Polygon rings are assumed to be encoded using the right-hand rule, i.e. outer rings are anti-clockwise and inner rings are clockwise. If the service does not guarantee that encoding, then set this flag to have polygon rings automatically oriented on import to avoid later problems when processing the data. Note: This requires a small amount of additional processing so only set if the ring direction is not guaranteed.
For X,Y,Z,M data	If you have data that is recorded as X,Y,Z,M, you must opt to ignore either Z or M values by choosing to use X, Y and M or X, Y and Z only. Note: If the default is left on and X,Y,Z,M is uploaded then an exception will be thrown as 1Integrate only supports X,Y,M or X,Y,Z. When consuming data with 3 ordinates, you must also select one of the two options: Select X,Y,Z to read in heighted data. Select X,Y,M to read in measured data.
Force geometry to be written X,Y,Z,M	Select to input a fourth Z or M ordinate for objects.
For X, Y, Z, M data: Use zero rather than Null or NaN when writing ignored ordinate	Select to write ignored values as zero in place of null/NaN (NaN is used for the PostGIS data store).

Output parameters

Parameter	Description
URL	The full JDBC connection string for connecting to the PostgreSQL/PostGIS database. Example:   jdbc:postgresql://host:port/database
Username	The username for your PostgreSQL/PostGIS database.

Schema	The schema to read tables from. Leaving this blank will result in all available schemas being read from while tables in the non-default schema are qualified with their schema. Note: The schema value is case sensitive
PostGIS Schema	The schema PostGIS was installed on, defaults to public.
Force geometry to be written X,Y,Z,M	Select to output a fourth Z or M ordinate for objects.
For X, Y, Z, M data: Use zero rather than Null or NaN when writing ignored ordinate	Select to write ignored values as zero in place of null/NaN (NaN is used for the PostGIS data store).
