Abstract
Previous research has demonstrated the feasibility of
deriving water depth information from Landsat Multispectral
Scanner (MSS) digital data. However, previously published
results, analysed together with two new case studies, show
that the magnitude of errors (approximately 1-2 meters) in
MSS single band depth estimates is too large for direct
production of bathymetric charts. Better accuracy is
possible, though, if MSS data are used to interpolate
conventional soundings between survey tracklines,
especially if the survey vessels obtain concurrent optical
ground truth data. If depth accuracy standards can be met,
the MSS interpolation approach will be extremely cost
effective. In addition, MSS imagery is shown to be a
useful tool for planning and managing conventional surveys.
A recommended set of procedures is outlined for
incorporating MSS image data into an operational
bathymetric mapping program. A comprehensive program of
development and operational demonstration surveys is
recommended to convincingly establish the utility and cost
effectiveness of these procedures.
