ARCHAEOLOGICAL SURVEY BY AIR - AN UPDATE FOR THE 1990S

The application of two types of electronic positioning systems, LORAN-C and the Global Positioning System (GPS), to the requirements and conduct of scientifically-controlled archaeological survey by air (as originally described in Gould, Richard A., 1987, ''Archaeological Survey by Air: A Case from the Australian Desert,'' Journal of Field Archaeology from the Australian Desert,'' Journal of Field Archaeology 14: 431-443) is evaluated. These systems afford greatly improved levels of accuracy in real time positioning during such surveys. The new generation of handheld GPS aviation receivers is especially well suited for use by archaeologists who plan to conduct controlled surveys on land and sea as well as in the air.
