Generation of rice crops temporal change maps with differential TanDEM-x interferometry

Abstract

A strategy to evaluate rice plant growth from TanDEM-X data is assessed in this paper. Single fields are segmented exploiting their early vegetative stage, when they are flooded. Height is then extracted from the bistatic interferometric phase in a field-by-field basis and temporal change maps useful to production estimation are generated. The accuracy of the plant height estimation is in a decimetric level.
