Source Description
Regions and Seasons: By the 20th century, digital technologies had replaced the older, manual mapmaking processes of copperplate engraving and lithography. However, visual techniques first developed in the mid-19th century such as shading variations were, and are still employed in thematic maps. This modern map illustrates monthly average temperatures for the United States from 1931-1960 using isotherms and a color scale from cold blues to warm reds. The large map in the center shows daily mean high and low temperatures during January, April, July and October for major cities across the country using two colors and a bar graph.
