I need to determine the mudflat area for a group of small islands in the Red Sea. I have read some publications and it seems to be possible using remote sensing, for example Landsat. But I am not exactly sure how to go about it, I know I should try to get images at low tide of my area of interest but I am not sure how to go about selecting the mudflats areas.
The most intuitive way seems to be to select pixels with a specific RGB combination, since the mudflats seem to have a very specific color. I am just interested in mapping the extent of the mudflats.
Someone has suggested to me "multispectral classification using a standard method like the maximum likelihood classifier" and "ratio analysis or decision-tree classifications" but I am not a remote sensing person and these seem to be way too technical.
