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:
- Upload a GeoJSON file to any online storage location like GeoJSON.io, Dropbox, Google drive.
- 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.
- In the Global Fishing Watch map toolbox, open the Layers tab.
- Click on Custom Layer.
- Click on GeoJson radio button.
- Add a custom layer in Global Fishing Watch, pasting your GeoJSON link.
- Customize the layer color, opacity and name.
WMS:
- In the Global Fishing Watch map toolbox, open the Layers tab.
- Click on Custom Layer.
- Click on WMS radio button.
- Add a WMS source url it usually has the following format: https://[DOMAIN]/[PATH]/wms for security reasons we only support services with SSL.
- If the server provides multiple layers you will get a list of all layers where you can select one or multiple ones.
- Customize the layer color, opacity and name.
Raster:
- In the Global Fishing Watch map toolbox, open the Layers tab.
- Click on Custom Layer.
- Click on Raster radio button.
- 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.
- Customize the layer color, opacity and name.
