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

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 procedures

2014年7月14日与7月21日，研究团队使用HyMap™传感器，于阿拉斯加山脉东部的纳贝斯内感兴趣区 (Area of Interest，AOI) 采集了高光谱成像光谱数据 (hyperspectral imaging spectrometer data)。本次研究的核心区域为阿拉斯加山脉东部一处分布有裸露斑岩矿床的偏远区域。HyMap™成像光谱仪在电磁波谱0.4至2.5微米的波长区间内，通过126个窄波段通道采集反射太阳光。本次数据采集采用标称6米的地面瞬时视场 (ground-instantaneous field of view，GIFOV)，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，以及一份用于阐释该数据集与采集流程的报告。
