پوشش زمین به پوشش فیزیکی و بیولوژیک در سطح زمین شامل آب، گیاه، خاک لخت گفته می شود. به دلیل وجود شرایط محدود کننده در مناطق خشک (کمبود آب، شوری خاک) مطالعه روند تغییر پوشش زمین از اهمیت زیادی برخوردار است. استفاده از سنجش از دور برای شناسایی و تشخیص پوشش در مناطق با گستره زیاد، جایگاه ویژه ای دارد. در این پژوهش برای ارزیابی تغییرات پوشش سرزمین در دشت مروست (منطقه ایی خشک در جنوب استان یزد)، از ...
In this study, we comparison of NDVI of ground measurement, atmospheric corrected ASTER LIB data and ASTER surface reflectance product (AST07) data to evaluate the accuracy of the ATCOR software atmospheric correction of Terra/ASTER data (Jun 30, 2002), using ground radiometric measurement data (ASD's FieldSpec® Pro). Our research selected the study area Sarobetsu Marsh located in coastal area ...
There is considerable interest in using remote sensing to characterize the hydrologic behavior of the land surface on a routine basis. Information on moisture fluxes between the surface and lower atmosphere reveals linkages and land–atmosphere feedback mechanisms, aiding our understanding of energy and water balance cycles. Techniques that combine information on land and atmospheric properties ...
atmospheric correction of the satellite data, for example correction of visible and near-infrared spectral bands, requires removing the adjacency effect that is due to the reflection from contiguous pixels. To evaluate the accuracy of the ATCOR software atmospheric correction method of Terra/ASTER data (Jun 30, 2002) we compared the NDVI parameters taken from different sources, such as ground m...
