Calexico serves as the focal point of this 2018 survey, positioned directly against the international border between the United States of America and Estados Unidos Mexicanos. The map documents a complex landscape of agricultural engineering within the Imperial Valley, defined by an intricate network of irrigation and drainage infrastructure including the Central Main Canal, Alamitos Canal, and Alder Canal. The grid of the city is dominated by civic landmarks such as the San Diego State Univ Imperial Valley Campus, while the surrounding rural landscape is divided by numerous lateral drains and roads like Anza Rd and Carr Rd. This cartographic record provides a precise view of the borderlands' hydrologic and municipal layout during the late 2010s.
