Aerial Photographs (from AMES Pilot Land Data System); USGS EDC, Sioux Falls

The aerial photography inventoried by the Pilot Land Data System
(PLDS) at NASA AMES Research Center has been transferred to the USGS
EROS Data Center. The photos were obtained from cameras mounted on
high and medium altitude aircraft based at the NASA Ames Research
Center. Several cameras with varying focal lengths, lenses and film
formats are used, but the Wild RC-10 camera with a focal length of 152
millimeters and a 9 by 9 inch film format is most common. The positive
transparencies are typically used for ancillary ground checks in
conjunctions with digital processing for the same sites. The aircraft
flights, specifically requested by scientists performing approved
research, often simultaneously collect data using other sensors on
board (e.g. Thematic Mapper Simulators (TMS) and Thermal Infrared
Multispectral Scanners). High altitude color infrared photography is
used regularly by government agencies for such applications as crop
yield forecasting, timber inventory and defoliation assessment, water
resource management, land use surveys, water pollution monitoring, and
natural disaster assessment.

To order, specify the latitude and longitude of interest. You will then be
given a list of photos available for that location. In some cases, "flight
books" are available at EDC that describe the nature of the mission during
which the photos were taken and other attribute information. The customer
service personnel have access to these books for those photo sets for which
the books exist.

NASA AMES研究中心的飞行员土地数据系统（PLDS）所编纂的航空摄影资料已转移至美国地质调查局（USGS）EROS数据中心。这些摄影资料由安装在位于NASA AMES研究中心高空及中空飞机上的相机获取。使用了几种不同焦距、镜头和胶片格式的相机，但以焦距152毫米、9英寸×9英寸胶片格式的Wild RC-10相机最为常见。正片透明胶片通常与数字处理相结合，用于对同一地点进行辅助地面检查。科学研究人员根据批准的研究项目提出的具体要求，往往同时利用飞机上的其他传感器（例如主题测绘模拟器（TMS）和热红外多光谱扫描仪）收集数据。政府机构通常定期使用高空彩色红外摄影进行诸如作物产量预测、木材库存和落叶评估、水资源管理、土地利用调查、水污染监测以及自然灾害评估等应用。订购时，请指定感兴趣的经纬度，您将获得该位置的可用照片列表。在某些情况下，EDC提供描述拍摄照片任务性质及其他属性信息的“飞行手册”。对于存在这些手册的照片集，客户服务人员可以查阅这些手册。
