After the grid outline is defined within the interface of Delft Dashboard the user can click on ‘Create grid’. The following routines will then be called:
- Determine the origin (xori, yori), spatial resolution (dx, dy), orientation (rot) and maximum bed level required (zmax) from the specified values in Dashboard.
- Create a full grid between these points (+ some buffer of 5%) based on the bathymetry active in Dashboard (default this is GEBCO ’08). This grid will already be defined in the active coordinate system the user specified (default this is WGS 84) .
- Creation a rectangular grid within the boundaries specified in Dashboard. The grid cells which are above a certain bed level (zmax) are deleted. A linear interpolation is carried between the full grid and the rectangular grid within the boundaries
