Thematic Maps
Completion requirements
In the previous video, the speaker said we use GIS to make thematic maps. However, humans have made detailed thematic maps by hand or with software that is not a GIS long before GIS became mainstream during the late 1980s and early 1990s. Today, GIS allows us to make these maps more quickly. Access to accurate data has increased the use of maps and facilitated the mapmaking process. These three thematic maps were created by hand before the advent of GIS.
