The combined use of high resolution SAR and optical images is of great interest, especially in complex scenes like urban areas. This requires accurate registration of images with big radiometric and geometric differences. This paper shows the accuracy that can be achieved by taking advantage of the geolocation accuracy of current sensors, instead of using more complex feature or intensity-based methods. An issue that can arise in layover areas is identified and a solution is shown. The approach is illustrated using very high resolution SAR and optical images.
