Hydrography90m layers download script

Here is a bash scripiting procedure to download tiled raster and vector files of the Hydrography90m dataset. Please see the paper by Amatulli et al. (2022) for further details.

Tile list

Donwload the tile list files.

wget https://gitlab.com/selvaje74/hydrography.org/-/raw/main/images/hydrography90m/tiles20d/tile_list.txt

Use the tile_list.txt file to download the full list of raster and vector files. Change the $(cat ../tile_list.txt) to a tile label (e.g. h30v12) in case you want download only one tile.
