APPLICATION OF A RADIOMETRIC MODEL FOR EVALUATION OF WATER DEPTHS AND VERIFICATION OF RESULTS WITH AIRBORNE SCANNER DATA

An existing deterministic, algorithmic model was used to simulate the radiative transfer of light through various depths of water. A computational formula was developed for a given set of experimental conditions and used to predict radiances for water in 0.6-m increments to a depth of 3.7 m. In a verification test, the capability of the model was evaluated by comparing the model simulation results with data collected using an airborne multispectral scanner. Validation results indicated that the model-simulated data and scanner-measured data were correlated. Spearman-Rho comparisons of calculated model wafer radiances and scanner brightness values indicated very good to excellent agreement at a high level of significance.
