Visible and near-infrared orthomosaic and orthophotos of Samoylov Island, Siberia, summer 2008, with links to data files

We obtained sub-meter resolution aerial images of Samoylov Island by mounting two Nikon D200 cameras on a helium-filled dirigible. Images were acquired in the visible (VIS) and near-infrared (NIR) ranges (together referred to as the VNIR range). The internal IR-filters were removed from the cameras in a laboratory (LPD LLC, USA), allowing them to capture a maximum range from about 330 to 1200 nm. A Schneider Kreuznach B+W 486 UV-IR cut filter was used for one of the cameras to obtain images in the VIS range, from about 400 to 690 nm, while the second camera was fitted with a Schneider Kreuznach B+W IR-filter 093 to acquire images in the NIR range, above about 830 nm. Flights took place at noon on sunny, cloudless days on August 1, August 9, August 15, and September 11, 2008. Flight altitudes ranged from about 400 m about 1000 m. […]

本团队通过将两台尼康D200相机安装在充氦气飞艇上，成功获取了萨莫伊洛夫岛的高分辨率亚米级航空影像。影像采集覆盖了可见光（VIS）和近红外（NIR）波段（统称为近红外波段）。在实验室（美国LPD LLC公司）移除了相机的内部红外滤光片，使其能够捕捉约330至1200纳米的最大波长范围。其中一台相机配备施耐德克鲁斯纳赫B+W 486紫外-红外截止滤光片，以获取约400至690纳米的可见光影像，而另一台相机则安装了施耐德克鲁斯纳赫B+W IR滤光片093，以获取约830纳米以上的近红外影像。飞行活动于2008年8月1日、8月9日、8月15日及9月11日中午进行，飞行高度介于约400米至1000米之间。
