Calexico serves as the focal point of this 2015 survey, situated at the southern edge of the Imperial Valley along the international border with Estados Unidos Mexicanos. The map documents a highly engineered agricultural landscape defined by an intricate network of waterways such as the Central Main Canal, Ash Main Canal, and the Alamo River. These systems, including specialized features like the Stout Drain Two and Beech Canal, illustrate the intensive irrigation required for the region's productivity.
