Usage

Sources: PGHydro README, pgh_output_en_au SQL

pgh_output_en_au provides an Australian-English PgHydro output schema. It creates localized export tables for drainage lines, drainage areas, and drainage points, plus a refresh function that populates them from the base PgHydro network.

Enable

CREATE EXTENSION postgis;
CREATE EXTENSION pghydro;
CREATE EXTENSION pgh_output_en_au;

Output Tables

The extension creates the pgh_output_en_au schema with tables including:

Refresh Output

SELECT pgh_output_en_au.pghfn_updateexporttables();

Run the refresh after recalculating or editing the source PgHydro objects.

Notes

Use this extension when the exported schema should expose Australian-English naming conventions while still being derived from the PgHydro drainage network.
