Topographic Normalization in Rugged Terrain
Remote sensing of rugged terrain is hampered by topographic effects on spectral signatures. The purpose of this study was to attempt normalization of the topographic effect encountered when analyzing Landsat Thematic Mapper (TM) imagery in the Rocky Mountains. Two normalization techniques were performed on a subscene of a TM image of Rocky Mountain National Park. The first technique was a band ...
متن کاملA Systematic Survey on Different Topographic Correction Techniques for Rugged Terrain Satellite Imagery
In remote sensed data, topographic corrections are very important to overcome the topographic effects such as shadow effects. These topographic effects occurs especially in case of rugged terrain because sun facing slope represents maximum reflectance values and opposite side slope represents minimum reflectance values. These topographic effects leads to an inaccurate classification into differ...
متن کاملAtmospheric Corrections to Satellite Radiometrie Data over Rugged Terrain
Radlometnc measurements from satelhtes m the solar portmn of the electromagnetic spectrum can be converted to measurements of surface eratance Over rugged terrain, the satelhte image must be precisely registered to a terrain data set For small areas a first-order polynomial mterpolatmn scheme is generally satisfactory for the geometric rectlficatmn If there are saturated plxels, a nearest-neigh...
متن کاملSimulation and Analysis of the Topographic Effects on Snow-Free Albedo over Rugged Terrain
Topography complicates the modeling and retrieval of land surface albedo due to shadow effects and the redistribution of incident radiation. Neglecting topographic effects may lead to a significant bias when estimating land surface albedo over a single slope. However, for rugged terrain, a comprehensive and systematic investigation of topographic effects on land surface albedo is currently ongo...
متن کاملPixel-based Minnaert Correction Method for Reducing Topographic Effects on a Landsat 7 ETM+ Image
The topographic effect on land surface reflectance is an important factor affecting quantitative analysis of remotely sensed data in mountainous regions. Different approaches have been developed to reduce topographical effects. Of the many methods, the Minnaert correction method is most frequently used for topographic correction, but a single global Minnaert value used in previous research cann...
