摘要：The space borne multispectral optical sensor data have been routinely used for assessment and monitoring ofnatural resources and environment. One of the major problems associated with the optical data is the availability ofcloud-free data during rainy season Cloud-penetration capability of microwave sensors data offers immense potentialin the study of highly dynamic phenomenon like floods. We have taken up this study to evaluate the potential ofRadarsat fine beam mode SAR data for detection of various terrain features; and to study the complementarity of thisdata with the optical sensors data from the Indian Remote Sensing Satellite (IRS-/C) Linear Imaging Self-scanningSensor (L/SS-1//) and Panchromatic sensor (PAN) over parts of Haryana state, India. The approach essentiallyinvolves speckle suppression, digital image registration, extraction of common areas; intensity, hue and saturation(IHS) transformation for merging SAR data with the optical sensor data and subsequent evaluation of these data setsfor detection of terrain features. The results indicate a good synergy of the SAR data with the optical sensor data inproviding information on various terrain features. The methodology and results are discussed in detail.
