摘要：

After recalling the various techniques used for wave measurement, this paper concentrates on the possibilities of using SPOT data for large scale wave analysis. Conditions for good wave pattern visibility are discussed from a theoretical point of view. In order to check the theory, examination of a large number of SPOT images was performed concerning the relation between viewing conditions and image quality. Using spectral analysis, a comparison is achieved using available simultaneous in situ directional data and SPOT images of an off-shore area in Brittany, France. Major conclusions are that both types of data compare rather well and that SPOT data could be used effectively in the coastal zone, provided that a proper software is designed to process small spatial windows. Recommendations are given for image acquisition procedure.
