Remote sensing of vegetation condition using high resolution digital multispectral imagery (DMSI) is an option for land managers interested in quantifying the distribution and extent of dieback in native forest. Crown condition is assessed as reference to the physical structure and foliage (i.e. density, transparency, extent and in-crown distribution) of a tree crown. At 20 sites in the Yalgoru...
خشکسالی یک پدیده و خطر پیچیدهی طبیعی، ناشی از شکستن تراز آبی است، که تأثیر آن همیشه در حوزه های زیست محیطی مشهود می باشد. بدین منظور، به کارگیری فنآوری سنجش از دور در پایش خشکسالی، با توجه به کمبود ایستگاههای اندازهگیری عناصر آبوهوایی، بسیار پراهمیت است. در این پژوهش شاخصهای پوشش گیاهی ndvi، rvi، vci، dsi، vswi، savi، tci و evi حاصله از تصاویر سنجندهی tm ماهوارهی landsat به تاریخهای: 13/6...
ecological studies based on field data have shown that vegetation phenology follows a relatively well-defined temporal pattern. this pattern, that is reflecting the cumulative temperature from the date of the beginning of the growth, can be represented by the use of a suitable model. due to the spatial, temporal, and ecological complexity of these processes a simple method to monitor phenologic...

The paper investigates the value of using distinct vegetation indices to quantify and characterize agricultural crop characteristics at different growth stages. Research was conducted on four crops (corn, soybean, wheat, and canola) over eight years grown under different tillage practices and nitrogen management practices that varied rate and timing. Six different vegetation indices were found ...
The present study demonstrates the application of remote sensing for the estimation of areas corresponding to crop and forest lands covered in the district of Aurangabad, (Maharashtra), India. The data acquired by IRS-P6 Advanced Wide Field Sensors (AWiFS) having 56m spatial resolution for the months of October & December 2012 which covered complete study areas with its swath of 740Km has been ...
Embedded Training Systems provide a new opportunity for training not only procedural or systems skills, but also the higher-level cognitive skills that are critical for successful performance on today’s battlefield. We have developed a principled approach for training the essential cognitive skills underlying high levels of situation awareness (SA) and decision making that can be easily employe...
Traditional methods of field measurement of soil moisture in addition to the difficulty, the need for manpower and money and fail to take place on a large scale to be able to show moisture. Therefore, remote sensing has become a widespread use .Landsat 8 satellite data and Sentinel-1 radar satellite from Tehran were provided. 72 soil samples were taken at the same time by satellite passing from...
