LISS IV sensor's data from IRS-P6 satellite was used to produce land use map of eastern region of Isfahan, the studied part of which has an area of 22121 hectares. Its three band data, namely band 2 (Green), band 3 (Red) and band 4 (Near infra red) of LISS-IV sensor images with 5.8 m ground resolution were georeferenced by nearest neighbor method and first-order polynomial model to the DEM map ...
The preparation of vegetation cover maps by used the land inventory and a traditional method has a lot of cost and time. But today, remote sensing is one of the main sources of data collection and information production for study and monitoring land resources, and was efficient tools for providing quickly and timely data and information needs for program planning in the natural resource filed. ...
طبقه بندی مناطق جنگلی استان گلستان به روش حداکثر احتمال با استفاده ازتصاویر ماهوار های ETM+ سال 2001
نزولات جوی در محیط عاری از پوشش گیاهی به علت کم بودن نفوذ پذیری خاک، به مقدار کم در زمین فرو می روند و بیشتر در روی زمین جاری می شوند و همین پدیده به همراه سایر عوامل باعث فرسایش خاک و آلودگی آب های سطحی و کاهش حاصل خیزی خاک می شود. متاسفانه در چند سال اخیر، کاهش چشمگیری در پوشش جنگلی به خصوص پوشش درختی در استان گلستان مشاهده می شود، به طوری که این مساله یکی از دلایل بروز سیل های مهیب بوده است....
This paper attempts to integrate satellite imagery such as Cartosat-1 with high spatial resolution and IRS P6 LISS IV with high spectral resolution using digital image fusion algorithms. This integration and mixing of hispectral and higher spatial data with complementary spectral and spatial characteristics, has proved to be promising to obtain images with high spatial and spectral resolution s...
Officials with the Long Island Sound Study (LISS) are presently reviewing the suite of indicators used to assess and report on Long Island Sound's ecological health and the programmatic success of the LISS. As part of this evaluation, managers seek to determine whether there are environmental variables that offer valuable information on ecosystem condition but that have not historically been tr...
This study attempts to measure and characterize urban sprawl using its multiple dimensions in the Jamnagar city, India. The study utilized the multi-date satellite images acquired by CORONA, IRS 1D PAN & LISS-3, IRS P6 LISS-4 and Resourcesat-2 LISS-4 sensors. The extent of urban growth in the study area was mapped at 1:25,000 scale for the years 1965, 2000, 2005 and 2011. The growth of urban ar...
The incidence of femoral fracture on hip prosthesis is increasing. Plate fixation is the method of choice when the prosthesis is stable. In fracture with proximal extension, the quality of the bone fixation is critical and, despite the development of anatomic plates, may be endangered when there are too few proximal screws. To resolve this issue, we recommend using a reversed LCP™ anatomic dist...
To compare the performance of seven currently available test systems in the detection of erythrocyte alloantibodies (ab), we tested in parallel 446 sera samples containing red cell ab [368 sera samples with ab that are assumed to be clinically significant (cs-ab) and 78 sera samples with ab that are assumed to be of minor clinical significance (ms-ab)] using the tube spin low-ionic-strength sol...
