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 con duct of scientifically-controlled archaeological survey by air (as ori ginally described in Gould, Richard A., 1987, ''Archaeological Survey by Air: A Case from the Australian Desert,'' Journal of Field Archaeol ogy from the Australian Desert,'' Journal of Field Archaeology 14: 431 -443) is evaluated. These systems afford greatly improved levels of ac curacy in real time positioning during such surveys. The new generatio n 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.
