This paper studies the model and techniques of extracting shallow water depth from TM images and image chart production in Nansha Islands and nearby sea area. On the basis of the conventional multi-band linear regression model, we develop a improved model by introducing a series of techniques including data pre-processing by group averaging, tidal correction, piecewise linear regression, data normalization, etc.. The improved model is more reasonable and accurate and suitable for large sea area. And we also present a set of techniques for remote sensing image chart production.
