Abstract (EDOC: 14978)
The simulation of remote sensing images is a valuable
tool for defining future Earth observation systems, optimizing
instrument parameters, and developing and validating dataprocessing
algorithms. A scene simulator for optical Earth
observation data has been developed within the Environmental
Mapping and Analysis Program (EnMAP) hyperspectral mission.
It produces EnMAP-like data following a sequential processing
approach consisting of five independent modules referred to as
reflectance, atmospheric, spatial, spectral, and radiometric modules.
From a modeling viewpoint, the spatial module is the
most complex. The spatial simulation process considers the
satellite–target geometry, which is adapted to the EnMAP orbit
and operating characteristics, the instrument spatial response, and
the sources of spatial nonuniformity (keystone, telescope distortion
and smile, and detector coregistration). The spatial module of the
EnMAP scene simulator is presented in this paper. The EnMAP
spatial and geometric characteristics will be described, the simulation
methodology will be presented in detail, and the capability
of the EnMAP simulator will be shown by illustrative examples.
