Volcanological studies of Neogene flood basalt groups in eastern Iceland
… porphyritic basalt group. Ground mapping and aerial photogrammetry were applied to assess the facies architecture of the groups, map their extent and distribution, measure the thickness of the lava flows and log the internal structure of representative flows. The source origin of each group …

Assessing the utility of NAIP digital aerial photogrammetric point clouds for estimating canopy height of managed loblolly pine plantations in the southeastern United States
… studies have investigated the ability of digital aerial photogrammetry (DAP), and more specifically NAIP, as an alternative to lidar as a means of estimating forest height due to its lower costs, frequency of acquisition, and wall-to-wall coverage across the United States. Field-collected canopy …

Automated Spatial Progress Monitoring for Asphalt Road Construction Projects
… point cloud data generated using unmanned aerial photogrammetry and a novel data simulation approach. A parallel as-planned progress estimate is also automatically prepared using 4D information, and the progress status determinations are made by comparing the two results. This solution was …

Medium-term response of lowland river reaches to changes in upland land use.
… the lowland channel have been quantified using aerial photogrammetry in ERDAS Imagine GIS. Channel instability is shown to increase significantly between 1963 and 1976, some 15 years after upland catchment afforestation. However, upland catchment bed load yields are shown to be of low magnitude …

Ancient stonewall fish traps on the south coast of South Africa : documentation, current use, ecological effects and management implications
… A total of 43 sets of vywers was located by aerial surveys, 30 of which are only accessible through private land. This affords them some measure of protection, together with five located off reserves, but diminishes their educational and tourism value. Four sets of vywers were mapped in …

Studio di fenomeni franosi a diversa scala, mediante tecniche multi-sensore da remoto.
Questa ricerca dottorale nel campo delle geo-scienze esplora l’utilizzo di tecniche di telerilevamento quali, la fotogrammetria aerea, la termografia ad infrarossi e l’interferometria satellitare (InSAR), per lo studio e la gestione dei rischi associati alle frane, attraverso un approccio …
