Abstract	Satellite image mosaics are commonly used for large-scale mapping purposes. Perpetual cloud cover may prohibit the mapping with electro-optical satellite imagery within a reasonable time interval, e.g. in tropical areas. In these cases, the additional use of SAR data can help to complement the image of the earth surface, as cloud-independent spaceborne SAR data has been proven to be a valuable thematic and topographic mapping source [1]. An effective way to realize an integrated image mosaic is the colorization of high-resolution SAR imagery by applying statistical filters and the adaptation of these false colors with respect to an optical reference. The creation of SAR images with a land-cover related color scheme has been shown before [2]. But generally, the resulting images have no relationship to the color impression of an optical scene. The motivation of the technique described in this paper is • to create automatically colour classified products directly from single polarized SAR images • to create seamless mosaics from colored SAR images • to mosaic colored SAR images with electro-optical imagery
