Video Surveillance Imagery of the Ivanpah Solar Electric Generating System (ISEGS) Facility Recorded by the USGS during Spring and Fall 2014

In this observational pilot study, we worked at the largest existing solar tower facility in the world (Ivanpah Solar Electric Generating System - ISEGS) to assess the efficacy of using radar, surveillance video, and insect trapping to monitor animals flying near the towers. During week-long site visits in May and September, we monitored the airspace surrounding towers and observed insects, occasional birds, and bats under a variety of environmental and operational conditions. This dataset is comprised of the unedited digital video imagery we gathered during those site visits. There are four types of video imagery included in the data set: (1) "EMCCD camera" is the output of an electron multiplying charge-coupled-device camera (model Hitachi KP-E500) operating in the near-infrared spectrum of light that was used image the top of a solar tower (Tower 3) during the nights of 14-18 May 2014. (2) "thermal camera" is the output of a surveillance camera that imaged in the thermal-infrared spectrum of light (model Axis Communications Q1921-E) that was used to monitor the tops of three solar towers and adjacent airspace from 14-22 May and 2-10 September 2014. (3) "ultraviolet camera" is the output of a camera that imaged in the ulraviolet spectrum of light (model Oculus Photonics UV-Corder) and was used to record miscellaneous imagery around the solar facility during May and September observation periods in 2014. (4) "WDR camera" is imagery gathered by wide-dynamic range, high-definition surveillance cameras that imaged in the visible spectrum of light (model Axis Communications Q1614-E) ---these cameras were used with various zoom lenses and were positioned both on the ground (most of May and September observations), but then mounted higher on a solar tower for closer imaging during the last two days of the September observation period. With the exception of the output of the ultraviolet camera, all video imagery is time (Pacific DST) and date stamped. In general, video monitoring proved useful for detecting and/or identifying some of the animals or objects moving through the airspace generally and near solar towers.

本观测性先导研究依托全球现存规模最大的塔式太阳能电站——伊万帕太阳能发电系统（Ivanpah Solar Electric Generating System, ISEGS）开展，旨在评估利用雷达、监控视频与昆虫诱捕技术监测塔式电站周边飞行动物的有效性。2014年5月与9月，研究团队开展了为期一周的现场观测，对塔式电站周边空域进行监测，在多种环境与运行工况下记录了昆虫、偶见鸟类与蝙蝠的活动情况。本数据集包含现场观测期间采集的未编辑数字视频影像。

本次数据集包含四类视频影像：
(1) "EMCCD相机"：指2014年5月14日至18日夜间，用于拍摄3号塔式电站塔顶的电子倍增电荷耦合器件（electron multiplying charge-coupled-device, EMCCD）相机（型号：日立KP-E500）输出的近红外光谱影像。
(2) "热成像相机"：指2014年5月14日至22日、9月2日至10日期间，用于监测3座塔式电站塔顶及周边空域的热红外光谱监控相机（型号：安讯士Q1921-E）输出的影像。
(3) "紫外相机"：指2014年5月与9月观测期间，用于记录塔式电站周边杂项影像的紫外光谱成像相机（型号：Oculus Photonics UV-Corder）输出的影像。
(4) "宽动态范围相机"：指采用宽动态范围高清监控相机（型号：安讯士Q1614-E）采集的可见光光谱影像。此类相机搭配多种变焦镜头，观测前期（5月与9月多数时段）部署于地面，9月观测期最后两日则挂载于塔式电站高处以获取近距离影像。

除紫外相机的输出影像外，所有视频影像均带有太平洋夏令时（Pacific DST）的时间与日期戳记。总体而言，视频监测技术可有效探测并/或识别空域内及塔式电站周边的部分动物或移动物体。
