  abstract = {{T}he ability of five satellite sensor bands ({IKONOS} band 4, {T}erra {ASTER} bands 3 and 4, and {L}andsat {ETM}+ bands 4 and 5) was examined to extract the waterline at coral reef coasts ({M}ajuro {A}toll, {M}arshall {I}slands) using different wavelength regions (near infrared [{NIR}] and shortwave infrared [{SWIR}]) and different spatial resolutions (4, 15, and 30 m). {A}fter performing georeferencing and normalization of the images, density slicing was used to extract the waterline. {C}omparisons of extracted waterline positions with ground-level data for eight transects and global positioning system ({GPS}) tracks of the island shorelines showed that {NIR} bands were superior to {SWIR} bands because of the characteristics of the coral reef coasts, including a lack of foam and suspended sediments (which can affect the {NIR} wavelength region, if present) and the presence of remnant water on reef flats during low tide (which can affect the {SWIR} wavelength region). {A} linear relationship was found between the estimation errors of waterline positions and the spatial resolutions of the {NIR} sensors. {A}nalysis on estimation errors and image costs showed that {T}erra {ASTER} band 3 was the most cost-effective sensor for extracting waterlines with reasonable accuracy. {T}he results serve as general guidelines for using satellite-derived data to estimate intertidal topography and detect and monitor shorelines in coral reef environments.},
