| Abstract: | The specific objectives of this investigation were: (1) To define and document a procedure by which Landsat multispectral scanner fata can be used to detect, identify, and estimate the areal extent of individual bodies of surface water. (2) Using this procedure and a data set corresponding to a study site within which the size and location of all bodies of surface water greater than 0.1 hectare are known, determine the level of accuracy to which one can detect and identify and estimate the areal extent of each body of surface water. A detailed procedure for using Landsat multispectral scanner data to detect, identify, and estimate the areal extent of individual bodies of surface water was defined, documented, and then used to process the selected Landsat data. The Landsat data chosen for this investigation represented a situation wherein classes of natural surface cover (wet, dark-black, bare soils) provided a significant amount of confusion during the spectral-separability phase of classifications. The study site selected for this investigation covered approximately 132,000 hectares in east-central Texas and contained 100 bodies of surface water that ranged in size from 0.83 hectare to 17.48 hectares. The classification results, using the recommended procedure, contained no areas in the study site which had been identified as water which were actually non-water.. |
