Raw imaging spectroscopy data collected for characterizing mineral resources near Nabesna, Alaska, 2014: Run08

Imaging spectrometer (hyperspectral) data were collected using the HyMap™ sensor over the Nabesna Area of Interest (AOI) in the eastern Alaska Range, July 14 and July 21, 2014. The primary study area was a remote part of the eastern Alaska Range where porphyry deposits are exposed. The HyMap imaging spectrometer measured reflected sunlight in 126 narrow channels spanning the 0.4 to 2.5 micron wavelength region of the electromagnetic spectrum. The data were collected at a nominal 6-m ground-instantaneous field of view (GIFOV). A total 1,900 square kilometers were collected. This data release provides flight line data for the survey and a report describing the dataset and procedures2014年7月14日与7月21日，研究团队使用HyMap™传感器，在阿拉斯加山脉东部的纳贝什纳感兴趣区域（Area of Interest，简称AOI）采集了高光谱成像光谱仪（hyperspectral imaging spectrometer）数据。本次研究的核心区域为阿拉斯加山脉东部一处偏远地带，该区域出露有斑岩矿床。HyMap™成像光谱仪可在电磁波谱0.4至2.5微米的波长范围内，通过126个窄波段通道采集反射太阳光数据。本次采集的地面瞬时视场（ground-instantaneous field of view，简称GIFOV）标称值为6米，总覆盖面积达1900平方千米。本次数据发布包含本次勘测的飞行航线数据，以及一份用于描述该数据集与采集流程的报告。
