Before you can use Ganos features, you must create the corresponding extensions in your database.
Create an extension using CASCADE
Run the following statement to create the ganos_trajectory extension. The CASCADE option automatically installs all dependency extensions (ganos_spatialref and ganos_geometry) in the correct order.
CREATE EXTENSION ganos_trajectory CASCADE;Create extensions without CASCADE
If your database engine version does not support the CASCADE syntax, install the three extensions manually in dependency order:
CREATE EXTENSION ganos_spatialref;
CREATE EXTENSION ganos_geometry;
CREATE EXTENSION ganos_trajectory;
