Login to your Global Fishing Watch account to upload personal reference layers.
Click the ‘+’ icon to add reference layers in a workspace, and then ‘Upload new reference layer’. You can upload polygon or points reference layers. Currently .zip and .json shapefiles are supported, alongside .csv files for points. Drag and drop your file into the Global Fishing Watch map or click to select the file. Add a name and description for the reference layer.
If your polygon dataset features multiple named areas (e.g. different named areas of interest within the same file), select that field from your dataset under ‘Field to name each area’ to import that data into the Global Fishing Watch map.
Confirm to add the reference layer to the map. This may take some time depending on the complexity of the dataset.
Once uploaded, you can toggle the reference layer on or off on the left hand side of the map. Access all your uploaded reference layers in your profile on the bottom left of your screen.
