Mapping soil water content under sparse vegetation and changeable sky conditions: comparison of two thermal inertia approaches
2013
A critical analysis of a thermal inertia approach to map surface soil water content on bare and sparsely vegetated soils by means of remotely sensed data is reported. The study area is an experimental field located in Barrax, Spain. In situ data were acquired within the Barrax 2011 research project. An advanced hyperspectral scanner airborne imager provides images in the visible/near-infrared and thermal infrared bands. Images were acquired both in day and night times by the Instituto Nacional de Técnica Aeroespacial between 12th and 13th of June 2011. The scene covers a corn irrigation pivot surrounded by bare soil, where a set of in situ data have been collected both previously and simult…
AN EXPERIMENTAL WORKFLOW FOR THE VIRTUAL RECONSTRUCTION OF ANCIENT STATUES
2021
The work aims to investigate the main steps of a virtual reconstruction process of ancient statues, inspecting theoretical and technical approaches. Two fragmentary Roman statues from the "Sanctuary of Isis", inside the Archaeological Park of Lilibeo-Marsala (Italy), were chosen as a case study. Trying to preserve the original artwork authenticity and the transparency of the reconstruction method, a workflow was developed following three steps: 1) 3D survey and reality based model production; 2) evaluation of reconstruction hypotheses based on a rigorous selection of reference sources; 3) 3D modelling and source-based model creation. Three models for multiple visualization purposes were car…

Развитие спутниковой системы ГЛОНАСС Созвездие позволило наличии эффективная система, которая обеспечивает важный вклад в любой ситуации съемки, Особенно, когда есть присутствие препятствиях к видимости спутника. Эта статья доклады о результатах испытаний, проведенных позиционирования с новым поколением Геодезические GNSS приемники поставляемых разными производителями для того, чтобы оценить вклад ГЛОНАСС созвездия NRTK (Network в режиме реального времени Кинематические) съемка в условиях критической GNSS спутников.Точные и конкретные результаты подтвердили двойного созвездия Приемники качества, даже тогда, когда Различия в экстремальных условиях были заметил.
