Addressing Emergency Flood Mapping And Monitoring Of Inland Water Bodies With Sentinel 1-2. Expectative And Perspectives
Abstract
The importance of water resources and the escalating frequency and intensity of flood events around the world during the last decades, emphasize the necessity of their timely and cost-effective monitoring by Remote Sensing techniques. The purpose of this paper is to present the current capacity of Earth Observation in detecting and monitoring flooded areas and inland water bodies, by means of different sensors (SAR, optical/IR). This is achieved by using results and experience gained within the International Charter and SAFER GMESS, ... , as well as from other relevant case studies such as ESA MOST Dragon project during the last decade and Take Five Experiment conducted by CNES-CESBIO. Based on this experience, the foreseen improvements that the Sentinel-1 and -2 missions will bring are presented, in the direction of meeting this new set of refined requirements, but also in the context of COPERNICUS. The user requirements for water resource and especially for flood monitoring are very high, with flash-floods being the most demanding case in terms of timely acquisitions of EO data. The Sentinels will be a milestone of the spatial and temporal improvements in Earth observation dedicated to risk management. While Sentinels will insure an efficient routine surveillance mission, VHR satellites like Pleiades will be tasked on demand over smaller high- risk areas.
