multispectral imagery, Eastern Island, mapping
"The use of multispectral imagery is particularly effective for mapping the archaeological record of Rapa Nui (Easter Island) due to the island’s lack of vegetation and exposed surficial lithic features. In 2010, Flaws demonstrated that near-infrared (NIR) imagery can be used to identify “lithic mulch” gardens, areas of cultivation that are enhanced through the prehistoric addition of broken bedrock. Here, we evaluate newly available, high-resolution short-wave infrared (SWIR) imagery for its potential to provide additional resolution and discrimination in mapping “lithic mulch” features."
