![]() ![]() If a connection or schema was created in a previous session, it can be chosen from the DB Connection or Schema dropdown lists. RiverGIS will automatically switch to the newly created schema, as shown below. Users can create a schema in a number of ways: using pgAdmin, QGIS’ own DB Manager or from within RiverGIS dialog by choosing Database > Create New Schema or clicking tool icon from Database toolbar. Therefore, the first step is to create a new schema for a model. ![]() Each model goes to its own schema, a kind of database directory for data grouping. Until a database and schema are set in RiverGIS window, most of the tools are inactive.Ī single PostgreSQL database can be used to store many models geometries. A term river database refers to a database used by RiverGIS. A fundamental difference from HEC-GeoRAS is that the RiverGIS uses a PostgreSQL database with PostGIS spatial extension for data storage (see Requirements for installation instructions).
