Polarimetry is the measurement and interpretation of different polarizations of electro-magnetic waves. Synthetic Aperture Radar (SAR) has been proven to be a powerful earth observation tool and emerging Polarimetric SAR (POLSAR) adds another dimension to SAR information content. Polarimetric SAR has been used in retrieval of soil moisture and surface roughness, snow and ice mapping and land-co...

BACKGROUND A supervised land cover classification was developed from very high resolution IKONOS satellite data and extensive ground truth sampling of a ca. 10 sq km malaria-endemic lowland in western Kenya. The classification was then applied to an investigation of distribution of larval Anopheles habitats. The hypothesis was that the distribution and abundance of aquatic habitats of larvae of...

In this paper we introduce a shadowing model for the volume scattering kernel component by land targets, such as vegetation, sand and soil. . The proposed BRDF model for heterogeneous land surfaces consists of three kernels, namely, an isotropic, a geometric and a volume scattering components and the new BRDF models with the shadowing volume kernel has been tested against the POLDER-1 BRDF data...

The objective of this study is to develop land cover classification algorithm suited for the eastern Asia by using multi-temporal MODIS land reflectance products; Surface Reflectance 8-Day L3 product and Nadir BRDF-Adjusted Reflectance 16-Day L3 product. In this study, land cover maps derived from these two kinds of source data products are generated and compared. Time-domain co-occurrence matr...

The kind of land use and intensity of its change is considered as important desertification indices in different models. Land use change is one of the main anthropogenic factors in the desertification. The current research was carried out around Imam Khomeini airport, with an area of 32000 km2, in order to evaluate mentioned area's land use changes effects during 1955-2003 on desertification. T...

abstract decadal changes in land use/land cover for balachaur watershed in nawanshahar district, punjab, india were studied using black and white aerial photographs for march 1984 on approximately 1:20,000 scale and multidate geocoded false colour composites (fcc) of irs-1d liss-iii on 1:50,000 scale for march 2002, september 2002, and may 2003 and interpreted visually to prepare land use/land ...

Amazonia holds the largest continuous area of tropical forests with intense land use change dynamics inducing water, carbon, and energy feedbacks with regional and global impacts. Much of our knowledge of land use change in Amazonia comes from studies of the Brazilian Amazon, which accounts for two thirds of the region. Amazonia outside of Brazil has received less attention because of the diffi...
