Tuber initiation and tuber bulking stages are critical part of various phenological phases for potato production. Tuber initiation covers the period from the formation of spherical rhizome ends, the f...
The black duck population has decreased significantly due to loss of its breeding habitat. Wetlands are an important feature that relates to habitat management and requires monitoring. Synthetic Apert...
土壤水分是水文、农业、生态等众多研究领域中的重要参数。基于已建立的简化土壤水分反演模型,结合全极化雷达数据的特征,消除简化模型中的粗糙度参数,以提高反演的精度。通过简化经验模型分析,结果显示VV/HH、VV/VH和HH/HV极化组合均能够较好地模拟裸土区土壤水分,其中VV/VH极化组合模拟结果最好。利用Radarsat-2数据反演黑河中游裸土区和植被区的土壤水分,并利用实测数据对结果进行验证。结果...
In fully polarized SAR (PolSAR) data the returned signal from a target contains all polarizations. More information about this target may be inferred with respect to single-polarization. Distinct pola...
The space borne multispectral optical sensor data have been routinely used for assessment and monitoring of natural resources and environment. One of the major problems associated with the opti...
This paper presents a new approach to extract urban landuse/land-cover information from high-resolution radar satellite data. Five-date RADARSAT fine-beam SAR images over the rural-urban fringe of the...
Land use information is one of the most useful input element in forming policies concerning to economic, environmental issues at national and also at global levels. With the view of these different sp...
Due to the accelerating global warming, droughts which cause severe damages especially in the agriculture became a very recurrent phenomenon in all over the world. Monitoring the characteristics of so...
Crop area estimates are crucial for the Common Agricultural Policy of the European Union to manage future intervention on stocks and export policies. The requirement is for early and accurate informat...
Synthetic aperture radar (SAR) data from RADARSAT-1 are an important operational data source for several ice centres around the world. Sea ice monitoring has been the most successful real-time operati...
Agricultural land use mapping and change detection are important for environmental assessment and crop yield estimation. An effective mapping and change detection of crop land use requires large ima...
This exploratory study examines the ability of grade 5 students to interpret selected elements of a Radarsat satellite radar image. The participants were provided with images of their neighborhood, do...
Early crop estimates for the Common Agricultural Policy of the European Union (EU), are a key point to manage future intervention on stocks. The current study project has the goal of assessing the ...
On May 20 and 29, 2012, two earthquakes of magnitudes 5.9 and 5.8 (Mw), respectively, and their aftershock sequences hit the central Po Plain (Italy), about 40 km north of Bologna. More than 2,000 siz...
East Oweinat district is located in the south Western Desert of Egypt. It is mainly occupied by outcrops of Archean to Early Proterozoic rocks of high to medium metamorphic grade and younger granitoi...
