Datum (shape of the earth) | WGS_1984 | WGS_1984 | The geoid is not explicitly defined in the CF convention. There was some discussion on this. |
Projection/Geographic Coordinate System | Spherical:WGS84, Cartesian: Unknown, SOBEK: Amersfoort new The region is only valid in the bounding box of the Netherlands but this restriction is not used. | Projection by grid mapping. Projection information is also stored. Data is alwasy provided in WGS84 |
In Delft3D/SOBEK there are two methods to store coordinates:
- Cartesian
- Spherical
Actually this does not say anything about the coordinates itself but it defines the distance function between points.
Questions:
Is it correct to assume that Spherical is always based on a WGS84 datum.
Naming convention
Locations (Staggering)
Grid/network
Aggregation methods
