Introduction
This 'Bathymetry' toolbox is universally written and can thus be applied for all models (e.g. Delft3D-flow, XBeach, etc.). The 'Bathymetry' toolbox allows importing, exporting and merging bathymetry 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.
Export
The 'Export' tab in the Working Space allows the user exporting data within a predefined Polygon. The Polygon can be defined using the key “Draw Polygon” and then drawing a polygon with the mouse (left click to draw the polygon, right click to close it).
- “Delete Polygon” is used to delete the polygon.
- “Load Polygon” allows loading an existing polygon file in ASCII format (*.pol).
- “Save Polygon” allows saving the polygon file in ASCII format (*.pol).
Import
The 'Import' tab in the Working Space allows the user importing data. Dashboard support multiple formats like ASCII grid, MAT-files, xyz-grid and netCDF and multiple coordinates systems.
