# Basemaps (Maps)

In SeaSketch, *Maps* refer to base maps that are authored in MapBox and then imported into SeaSketch. You will need to create a MapBox account, create Mapbox style, publish it and then add the URL to your SeaSketch project.  

In Data Layers, choose Maps > Add New Map > By URL > and past the link below into the field that says Style Location. 

mapbox://styles/seasketch/clhao1xum01w901qm2wkd06tc

Select an area of the map to create a thumbnail.&#x20;

After capturing and saving the thumbnail, the new map will be viewable by all users. They do not require "publishing" as do data layers shown above.&#x20;
