ISRIC - World Soil Information Database



© European Communities, 1995-2007Since its beginning in 1966, ISRIC - World Soil Information has built up a collection of more than 20.000 articles, country reports, books and maps with emphasis on the developing countries. The subject emphasis is on soils, but related geographic information on climate, geology, geomorphology, vegetation, land use, and land suitability is also important. The map collection contains over 6000, mainly small-scale (1:250.000 or smaller) maps. more...

Spatial Modeling of Soil Salinity Using Remote Sensing, GIS, and Field Data

This study has shown the benefit of using satellite images in generating accurate soil salinity maps. Corn and alfalfa crops were selected as indicators of soil salinity. Five images were acquired from Aster, Ikonos, and Landsat to check the correlation between measured soil salinity and remote sensing data. Observed data was used in conjunction with satellite images. Three models were applied to predict soil salinity from remote sensing: the ordinary least squares model (OLS), spatial autoregressive model (SAR), and modified kriging model.
