MothballedThe Geoscience Spatial Framework (GSF) is a database for the storage of 3D modelled surfaces and volumes, in a data structure that is independent of the originating model software. It is based on the simplest possible spatial unit (the point), which can be obtained from the export formats of most modelling packages. The points are stored as Latitude/longitude pairs referred to the ETRF89 datum, although the elevation does not rigorously conform. Topological information (triangulation) is provided, which indicates how points may form surfaces or volumes. The GSF allows models to be linked to a range of attributes describing their properties and to integrate with other BGS data sets, including metadata.
