Mapbox is a versatile mapping platform that allows users to build maps and apps. This task sheet will focus on Mapbox Studio, an interface for styling custom basemaps. This task sheet will guide you in adding vector datasets to your basemap in Mapbox Studio and will build upon skills developed in a previous task sheet, Custom Basemaps with Mapbox Studio PM2082-17C. We will build a basemap that depicts the last ten years of RAGBRAI routes across Iowa.
