EeteS: An end-to-end image simulation tool applied to THE EnMAP hyperspectral mission

The sensor end-to-end simulation software EeteS has been developed within the framework of the Environmental Mapping and Analysis Program (EnMAP) mission. EeteS is capable of simulating EnMAP-like raw image scenes (L0) taking into account a variety of instrumental and environmental configurations. Furthermore, EeteS allows simulations of EnMAP reflectance images carrying out the complete L1 and L2 processing chains and necessary sensor calibration steps. The sequential processing chain of the simulator consists of several independent modules that are briefly described in this paper. Analysis of the intermediate and final EeteS simulation products has shown the accurate, reliable and consistent performance of the developed modules enabling the system to support technical decision-making processes required for the development of the EnMAP sensor. Besides the optimization of fundamental instrument parameters, data simulated by EeteS is already used for the development and evaluation of data pre-processing and scientific-exploitation algorithms.
