Exploring the feasibility of monitoring the evolution of the spatial distribution of intertidal eelgrass from multispectral images combined with measures spectroradiometric land in confined areas. This spatial distribution for the amount of intertidal eelgrass present through the calculation of a vegetation index . This vegetation index can then be connected to the biomass.

A new approach to mapping based on an optical model was developed and used from hyperspectral aerial images to determine the biofilm microphytobenthos and estimate their biomass in confined mudflats
