摘要：

A method is presented for extracting wetland areas in northern high-latitude zones using Normalized Difference Vegetation Index (NDVI) and land surface temperature (T-s) calculated from midday NOAA/AVHRR data. Wetland areas have been distinguished from other land-cover types using signatures on a scattergram of NDVI vs. T-s. The method was applied for extracting wetland areas in the basin of the Ob River in the west Siberian lowland. The result have been verified with ground-truth data and land-cover classification results obtained from high-resolution satellite images.
