7 ARCHAEOLOGY ON EASTER ISLAND: REMOTE SENSING FOR LOW-IMPACT ARCHAEOLOGICAL STUDY OF RAPA NUI'S (EASTER ISLAND) MONUMENTAL STONE ARCHITECTURE

This study uses remote sensing techniques to study ahu (monumental ceremonial platforms) on the island of Rapa Nui (Easter Island). The first phase of the project used commercial satellite images to locate ahu and create a comprehensive GIS database to be corroborated during future ground survey. To supplement the satellite images, a second phase of the study evaluated kite photography- a low-cost, non-destructive, low-impact and culturally sensitive way to supplement the resolution of the satellite images. Kite photography was used to photograph ahu and ground targets were used to mosaic photographs together. From the resulting image, traditional archaeological plan view maps were made. The micro and macro survey of archaeological features in this study will contribute first towards protecting the famous heritage sites on Rapa Nui for the Rapanui people and for future research. Data will be used in continuing studies that aim to scientifically understand cultural and environmental change on the island
