First, look at ALL of the available aerial photographs. endobj %���� Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus is in contrast to on-site observation. Black Maps is San Francisco-based photographer David Maisel's new book of over 100 photographs spanning his career. Photography can provide black-and-white, color, or color-IR data in either film or digital form. Hence, the photographic process literally squashes a three-dimensional feature onto a plane that lacks a vertical dimension, and image features above or below mean ground l evel are displaced from their true horizontal location.
