# Towards the simulation and inversion of user-defined inland water imaging spectrometer data

Odermatt, D; Knaeps, E; Raymaekers, D; Sterckx, S; Kneubühler, M; Schaepman, Michael E (2010). Towards the simulation and inversion of user-defined inland water imaging spectrometer data. In: Hyperspectral Workshop 2010, Frascati, IT, 17 March 2010 - 19 March 2010, 1-5.

## Abstract

An at-sensor radiance simulation environment based on Hydrolight and MODTRAN-5 was set up for the evaluation of arbitrary combinations of sensors, methods and targets for the investigation of inland water quality. Each Ls simulation requires three MODTRAN- 5 runs, whereas two runs are needed for the calculation of the specular reflectance. Simulation results can be used in the preparation of specific algorithms for future sensors, e.g. the Airborne Prism Experiment (APEX), as well as for vicarious calibration, to estimate the noise sensitivity of a specific algorithm or in general project planning.
