APPENDIX
DESCRIPTION OF THE GEOBATHY SOFTWARE
NATURE AND FUNCTIONALITIES
The GEOBATHY software for "bathymetric modeling of shallow bottoms using multispectral imagery" is based on simplified equations of the radiative transfer of light through water found in manuals. Maritorena, Morel and Gentilly* have recently confirmed that these equations can be safely applied to radiance data sets obtained using remote sensing techniques. It is also based on optical properties of marine waters described by Jerlov in his reference book "Marine Optics" (1976), which was first published in 1963.
Under these conditions, and provided that part of the multispectral imagery represents dry land, the software provides complete calibration of calculations, thus obtaining an estimate of depth and reflectance of the shallow bottom, without using any field data.
The GEOBATHY software has been successfully tested, using a databank of multispectral SPOT satellite images representing a great number of islands and atolls in French Polynesia, and sparse field data (existing maps, data from SHOM).
TECHNICAL SPECIFICATIONS
The GEOBATHY software is written in C programming language.
It is run on a computing platform under the UNIX operating system.
It is based on the image format and functionalities of the GEOimage image processing system, marketed by the French firm GEOimage, France.
It is exclusively adapted to processing the three channels of the multispectral image of the satellite SPOT, i.e., the XS1 (green at 550 nm), XS2 (red at 650 nm) and XS3 (near infrared at 850 nm) bands.
Its execution results in one image of the computed water depth and one image of the computed bottom reflectance, both in the GEOimage image format.
ACCURACY FOR WATER DEPTH
According to Philpot**, and under the best imaging conditions (i.e., clear skies, absence of wind and clouds, sun high in the sky, near-vertical viewing), the error calculation for the most frequent cases of SPOT or Landsat satellite images (8-bit coded images), should provide accuracy for the computed depth on the order of 10% of the actual depth.
ACCURACY FOR BOTTOM REFLECTANCE
There is no known, published reference which can be used as a specification. However, it can be mentioned that, according to the equations used (those used by Philpot** and Maritorena et al.*), accuracy for bottom reflectance will necessarily be an exponential function of accuracy for depth of that bottom.
