Bathymetry is the ocean's depth, often relative to mean sea level, and for every numerical study an important aspect. However, bathymetric data is not often easy to acquire and combine due to differences differences in vertical and horizontal coordinate systems. The 'Bathymetry' toolbox allows for easy importing, exporting and merging bathymetry of bathymetric data from a number of on-line and open source datasets. The bathymetric data is available with different resolutions according to different zoom levels (so-called tiles) indicated in brackets in the column resolution.

The 'Export' tab in the Working Space allows the user exporting to export data within a predefined Polygon. The A Polygon can be defined using be made by using the key “Draw Polygon” and then drawing , which enables the user to draw a polygon with the mouse (left click to draw the polygon, right click or click or double click to close it). An example can be found in the Figure below.

- Select file. By selecting the file file , Delft Dashboard determines how many cells it is going to createcells are needed.
- If you use Matlab or NetCDF as input: make sure the bathymetry information is saved within the variables x, y and z. (lower case)
- Edit settings. Define, for example, the coordainte system and , the filename and attributes.
- Generate Tiles. The bathymetry set will be created for Delft Dashboard using tiles.
