The goal of this activity is for students to learn how to design a basemap. In geospatial science, a basemap refers to a collection of data layers that are used to create a background for the map. The purpose of a basemap is to provide context for the primary data, both spatially and thematically. Typical basemap layers include roads, administrative boundaries, and aerial imagery. In this activity, you will gather the data necessary to construct a basemap for the City of San Francisco. You will then use what you learned in this chapter to design a basemap, which will be used as the background for a thematic poster map.
