ABSTRACT:During last years the need of knowing the forest in its various aspects, quantitative and qualitative, has enabled the appearance of a new technique forestry geomatics. Named as "the science of future" this technique integrates multiple technologies such as Remote Sensing, Airborne Photogrammetry, LIDAR, Geographic Information System (GIS), Global Positioning Systems (GPS) or classical geodetic technology for data acquisition, data processing, data analysis and data management. The purpose is to provide specific information regarding the evaluation natural forestry resources. In this paper will be presented the utilization of terrestrial 3D laser scanner and GIS technologies in forestry inventory.
In designing artwork as bridges, hydraulic calculations have a very important role due to the fact that they are behind their sizing. Bridge designer must therefore possess knowledge of hydrology, hydraulics of bridges and river banks regularization. A problem that arises during the design stage of bridges is the scour phenomenon surrounding bridge pier. Over time, there have been conducted a number of studies which led to the provision of a plurality of mathematical models that are intended scour prediction. In the present article we will present an experimental study to determine the bed profile and measurement of scours products around a pier bridge using 3D terrestrial laser scanner.
In the era of rapid urbanization which has a great implication in converting the natural landscape into artificial surfaces, Land Surface Temperature (LST) is an important parameter which plays an important role in the studies of urban thermal environment, meteorological, hydrological and climatological applications and Global climate change. Data and images acquired from satellites offer information that can facilitate public and private decision - making. This study investigates the Land Surface Temperature (LST) determination in Bucharest city, which is the capital of Romania using geospatial data provided by the Sentinel - 3 SLTR instrument satellite mission and Geographic Information System techniques. For this purpose, were processed two images acquired on July 2020 and July 2021. The mapping result reveals that the surface temperature is around 32 - 50 Celsius degrees during summer period and had been recorded in the city center and in the industrial area of the city. The obtained temperature interval is reliable, comparing with the measurements realized by weather monitoring stations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
