The spectro-goniometer consists of a Manual Transportable Instrument platform for ground-based Spectro-directional observations (ManTIS), and a hyperspectral sensor system. ... This article presents and technically describes a new field spectro-goniometer system for the ground-based characterization of the surface reflectance anisotropy under natural illumination conditions developed ... Acknowledgments The platform and resultant ManTIS field spectro-goniometer development would not have been possible without the know-how, private engagement, and financial support of various people and ...doi:10.3390/s131216105 fatcat:fr2hqh5usjdgbcno6rvh6icaiy
Finally, we found that studies that sampled only a narrow range of biomass and NDVI produced equations that were more difficult to correct for BRDF effects. ... Satellites provide the only practical source of data for estimating biomass of large and remote areas such as the Alaskan Arctic. ... Acknowledgments Field work was carried out within the framework of a US-German expedition in summer 2012, and part of the hy-ARK-VEG (hyperspectral method development for ARCtic VEGetation biomes) project ...doi:10.1088/1748-9326/11/12/125002 fatcat:4ymttm6qfzdxtn7omws4xtt2he
