Vectorized Shoreline of Tutuila, Ofu, Olosega, Rose, Swains, and Ta'u American Samoa, Derived from IKONOS Imagery, 2001

IKONOS imagery was purchased to support the Pacific Islands Geographic Information System (GIS) project and the National Ocean Service's (NOS) coral mapping activities. One-meter panchromatic and four-meter multi-spectral data were purchased for each study area. A digital vector shoreline was manually digitized from the one-meter panchromatic imagery to provide accurate, up-to-date shoreline data.
