LiDAR Imagery Confirms Extensive Interior Land-Use on Tutuila, American Sāmoa

Abstract

Analysis of LiDAR imagery for Tutuila, American Sāmoa, confirms extensive modification of the interior landscape.
Using both field-generated maps and feature descriptions as a guide, we identify numerous terraces and other probable
feature types in LiDAR images for three areas of Tutuila. Our results are applicable across the island.
