Applicability of multifractal features as global characteristics of WorldView-2 panchromatic satellite images

Road Detection in Panchromatic SPOT Satellite Images

The goal of this study is to detect the main road network in high resolution, panchromatic SPOT satellite images. The applications of automatic road detection have attracted considerable interest in this problem [1–4], but no present system is completely satisfactory from the point of view of detection time, image size and required human intervention. We describe an automatic procedure for road...

Fusion of Multispectral and Panchromatic Satellite Images in Environmental Issues

Image fusion of multispectral and panchromatic satellite image is used to combine spatial detail of the panchromatic image of high spatial resolution and spectral information of multispectral image of low resolution, in order to create a synthetic multispectral high-resolution image. This process is called pansharpening and the resulting image, has among others, improved visual quality and visu...

Retrieval of Water Optical Properties from Eight-spectral Band Worldview-2 Satellite Images

Conventional ocean color satellites sensors are not very suitable for inland and coastal waters applications due to their low spatial resolutions. High spatial resolution satellite sensors are required to monitor the water quality of inland and coastal waters. The conventional high-resolution satellites such as Landsat, SPOT and IKONOS have limited number of spectral bands. In comparison, the W...

Comparison of Different Algorithms to Orthorectify WorldView-2 Satellite Imagery

Due to their level of spatial detail (pixel dimensions equal to or less than 1 m), very high-resolution satellite images (VHRSIs) need particular georeferencing and geometric corrections which require careful orthorectification. Although there are several dedicated algorithms, mainly commercial and free software for geographic information system (GIS) and remote sensing applications, the qualit...
