edit the coastline

[Alonso112358]

hi , I'm running "example_leeway.py " and I just wonder if is there any chance to edit the coastline, I'm asking because my seed leeway elements are near the coast, and sometimes its position fall on the land. thanks !!

Hi,

The default coastline is from GSHHG, and is not straightforward to modify. However, it is possible to use your own shapefile, or an ocean model raster landmask: https://opendrift.github.io/gallery/example_shape_landmask.html https://opendrift.github.io/gallery/example_model_landmask.html

Anyway, particles seeded on land, will be moved to the closest point in ocean at the first timestep, as long as config setting seed:ocean_only is set to True (default)

Thanks so much for answering !! By the module example leeway, Is it a 3D or 2D model? I'm asking because the example by default use surfaces current (norkyst800_subset_16Nov2015.nc) and when download netcdf files from copernicus I also use surface current (uo and vo), or it depends of the input?

Leeway is 2D model, so it only uses surface current
