Object-based image analysis provides a powerful tool for using remote sensing data as a means of identifying archaeological features. Object-based image analysis has multiple advantages over pixel and spectral based tools, because it isolates features in image data based on a combination of spatial, spectral, and geometric characteristics. Using high spatial and spectral resolution imagery available for Rapa Nui (Easter Island, Chile) and the Trimble eCognition software package, we explore how...
Spatial Analysis of Prehistoric Garden Features on Rapa Nui (Easter Island, Chile) (2015)
Manavai are circular walled stone gardens used for cultivation by the prehistoric populations of Rapa Nui (Easter Island, Chile). Though not fully mapped, over 1000 manavai are known across the island in a distribution that reflects dispersed settlement patterns. Object-based image analysis of newly available high-resolution imagery of the island offers a mean of systematically identifying manavai features. Using the results of these analyses, we examine the spatial patterns of manavai and their...
