Interferometric data processing requires careful calibration and validation of the complex input products. Interferometric calibration comprises geometric and phase accuracy aspects. With respect to geometry, orbit and timing parameter have to be calibrated in order to allow accurate geo-coding and optimal processing of the interferometric products. Phase accuracy of the input complex products ...

This paper illustrates some results obtained in the frame of an experimental campaign carried out on several wheat fields of the Matera (Italy) site, from February 2003 to June 2004. During this period, ENVISAT ASAR data, at alternating polarization mode and at different incidence angles, were acquired on the area roughly every week. Ground data such as soil moisture content, wheat biomass, LAI...

Optical satellite albedo observations of forests suffer from understory contamination, but C-band microwave reacts mostly with the canopy. This paper studies whether or not adding ASAR backscattering information could enhance optical albedo retrieval accuracy. We compare SPOT-4-retrieved reflectances combined with ASAR backscattering ratios with solely optically retrieved SPOT-4 NIR albedo, and...

ABSTRACT A method has been developed to apply multi-temporal Advanced Synthetic Aperture Radar (ENVISAT/ASAR, C-Band) images to snow cover monitoring and mapping in mountainous areas. A multi-temporal dataset that includes sequences of ascending and descending ASAR wide swath and beam mode IS2 scenes acquired over Switzerland was investigated. The images were geometrically corrected to remove r...

This paper summarizes the first results on interferometric ENVISAT/ ASAR image mode products [1]. We analyzed timing and geometric accuracy as well as the phase of a first interferogram from an IS2 image mode data set (VV polarized). According to the schedule the image mode products of this beam products are the first to be validated [2]. This interferogram is one of the first ENVISAT/ ASAR int...

due to human beings’ aesthetic sense, they have always been engaged in embellishing their living environment throughout the history. given the different culture, customs, beliefs and even varied policy of each society, the applied arts or decorative styles have constantly been evolved. the qajar architecture was influenced by russian and central europe styles, and by combining them with the ira...

the main purpose followed in this study was to evaluate the role of social capital on organizational learning (ol) of jihad-e-agriculture organization's staffs. the statistical population consisted of all staffs of jihad-e-agriculture organization in kurdistan province (n=150). applying census, a questionnaire was sent to all the members of the study from whom 124 members finally filled in...

statement of problem: considering the importance of the occlusal plane orientation in complete denture prostheses, a study was conducted on the relationship between this plane with ala-tragus and camper’s lines in soft tissue among individuals with class iii malocclusion, in mashhad school of dentistry. purpose: the aim of the present study was to define the best soft tissue index by which the ...

The main objective of this project is to develop and test methodology using ENVISAT ASAR data for agricultural applications, with an emphasis on land use, land cover classification and rice mapping. An optimal pre-processing chain for ASAR data is first constructed to provide input data to the classification steps. Experiments at the Zhangzhou test site, Fujian province, southern China, indicat...
