First, you must be logged into your Global Fishing Watch account. There are multiple ways to upload your custom layers to the map. We currently support 3 standards: GeoJSON, Web Map Services (WMS) and Rasters. Below you will find some notes of how to add each of these types.

GeoJSON:

1. Upload a GeoJSON file to any online storage location like GeoJSON.io, Dropbox, Google drive.
2. Copy the link to that uploaded file. Make sure that when you paste that link in the browser you download the GeoJSON and you don’t trigger any preview mode.
3. In the Global Fishing Watch map toolbox, open the Layers tab.
4. Click on Custom Layer.
5. Click on GeoJson radio button.
6. Add a custom layer in Global Fishing Watch, pasting your GeoJSON link.
7. Customize the layer color, opacity and name.

WMS:

1. In the Global Fishing Watch map toolbox, open the Layers tab.
2. Click on Custom Layer.
3. Click on WMS radio button.
4. Add a WMS source url it usually has the following format: https://[DOMAIN]/[PATH]/wms for security reasons we only support services with SSL.
5. If the server provides multiple layers you will get a list of all layers where you can select one or multiple ones.
6. Customize the layer color, opacity and name.

Raster:

1. In the Global Fishing Watch map toolbox, open the Layers tab.
2. Click on Custom Layer.
3. Click on Raster radio button.
4. Add a Raster source url it usually has the following format: https://DOMAIN]/[PATH]//{z}/{y}/{x}.jpg for security reasons we only support services with SSL.
5. Customize the layer color, opacity and name.
