A Model of Topographic Correction and Reflectance Retrieval for Optical Satellite Data in Forested Areas

Topographic correction is a necessary step of pre-process in the remote sensing application in rugged terrain. Most of traditional topographic correction methods are empirical and statistical based. These methods have the advantage of facility; however they also have some disadvantages, such as lack of comprehensive physical analysis, subjectivity in operation, separation of atmospheric correct...

Topographic Correction for Differential Illumination Effects on Ikonos Satellite Imagery

The problem of differential terrain illumination on satellite imagery has been investigated for at least 20 years and has not been solved satisfactorily. Most past research has been conducted on Landsat imagery where the look angle is nadir. There is no research on topographic correction of IKONOS imagery, which has a higher spatial resolution. The high spatial resolution of IKONOS imagery requ...

Mine Subsidence Monitoring Using Multi-source Satellite SAR Images

Ground subsidence due to underground mining has posed a constant threat to the safety of surface infrastructure such as motorways, railways, power lines, and telecommunications cables. Traditional monitoring techniques like using levels, total stations and GPS can only measure on a point-by-point basis and hence are costly and time-consuming. Differential interferometric synthetic aperture rada...

The Influence of DEM Accuracy on Topographic Correction of Ikonos Satellite Images

There is no research which specifically investigates the influence of the Digital Elevation Model (DEM) on topographic correction of satellite images. Such an investigation is necessary in view of the very high resolution (VHR) of recent sensors such as Ikonos and QuickBird and the low availability of accurate height information for the derivation of slope and aspect values. A comparative study...
