This document describes a low-cost technique for developing countries to obtain high-resolution aerial photographs using balloons and digital cameras. The technique involves using balloons to lift digital cameras into the air to take photographs, and then using GPS to georeference the photos. Initial field tests showed promising results capturing images with resolutions of 20-30 cm. The document provides examples of how this technique was used in Cambodia for regional planning, forest mapping, urban planning, and more.
