Third Party Data

With all datasets, it is important to check if there is an authoritative dataset that should be used. The sources below are diverse and may offer more accuracy, but they are not necessarily authoritative.

Global datasources​

A number of global datasources are published in the global-datasources project.

These are already published as cloud-optimied GeoTIFF's and you can use their URL's directly with loadFgb.

Marine Regions​

The Marine Regions website is a good starting point for boundaries relevant to marine planning including EEZ, territorial sea, etc.

It's not always the most accurate, but it has global coverage. If the coastline for the EEZ dataset is not accurate enough you can take the "marine and land zones" dataset and then punch out the land holes using the OSM land dataset below.

OSM Land​

The OSM Land is a regularly updated coastline dataset. This can be a more accurate dataset than Marine Regions, particularly with coverage of very small islands that are near sea level. This dataset is the most likely to match up with map providers like Mapbox.
