PErfECT developed different photogrammetry tools to enhance the red coral population surveys based in: (i) automatic orientation on coded quadrats, (ii) use of NPR (Non Photo
The objective of this study is to investigate the use of high resolution photogrammetric point clouds together with two novel hyperspectral cameras in VNIR and
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XLII-3/W3, 2017 Frontiers in Spectral imaging and 3D Technologies
The suitability of UAV-based photogrammetric point clouds and hyperspectral imaging was investigated in mapping biodiversity indicators such as structural complexity
The point cloud tree extraction techniques operate on TLS data and models the biomass using the estimated stem and canopy volume as inde- pendent variables.. Eight spruce and eight
lower mean error for the given material. The tables show that it is not possible to define the best algorithm for the specific scenario, without any other evaluation test, since
The classifications using the best combinations of features were more accurate than those using the image-based and point- based features and the combination of
We have shown that if spectral data include missing wavebands or values K-spatialmedians method with available case strategy can be applied in clustering.. The results are meaningful
