Endorheic waterbodies delineation from remote sensing as a tool for immersed surface topography

Abstract

Since several decades, it becomes possible to delineate waterbodies and their dynamics from optical or radar images, that are now available at high spatial and temporal resolutions. We present here an interpolation approach that takes benefits from this waterbodies delineation in endorheic areas. It consist in computing isovalue contourlines to improve topography estimates classically obtained from measurement points only. The approach, based on a minimisation problem, uses Thin Plate Splin interpolation functions, whose coefficient are determined along with the unknown water level of each curve. Results obtained on a generated topography show that this approach, applied with three contour-line curves, yields a lower root mean square error using only one measurement point compared to the one obtained with nine points and the classical approach.
