Public Affairs Office (PAO) Image Gallery

The Public Affairs Office (PAO) Image Gallery collection contains a wide variety of images ranging from low altitude aircraft to satellite and NASA imagery. The collection includes historical imagery from multiple data systems used in publications, posters, and special projects over decades of EROS science. A majority of these images were archived on film media. The PAO film records were scanned, indexed and are searchable for no-cost downloads to the science community, educators and general public. Also included in this collection are the Earth As Art 1, 2, and 3 collections, Landsat State mosaics, and State elevation mosaics. Each PAO image tells a different story of natural disasters, the natural beauty of Earth phenomena, and unique perspectives of rivers, lakes, seas, mountains, icebergs around the world. The Earth As Art collections were developed for their aesthetic beauty rather than scientific interpretation - http://eros.usgs.gov/imagegallery. Over time, the PAO will continue to grow as data sets from the Image of the Week are added and additional film images are scanned for data access. The Image of the Week posters are scientific observations that highlight current conditions or changes in water resources and land cover over time - http://eros.usgs.gov/imagegallery/image-week- 2. Downloads are available in TIFF (Tagged Image File Format). Approximate coordinates have been identified for this collection; images have not been georeferenced and no map projection or datum information is provided.公共事务办公室（Public Affairs Office，PAO）影像图库馆藏涵盖了丰富多样的影像资源，类型涵盖从低空航空器拍摄影像、卫星影像到美国国家航空航天局（National Aeronautics and Space Administration，NASA）影像等多个范畴。该馆藏包含数十年来地球资源观测与科学中心（Earth Resources Observation and Science，EROS）科研工作中，用于各类出版物、海报及专项项目的多套数据系统所生成的历史影像。其中绝大多数影像曾以胶片介质进行归档存储。公共事务办公室的胶片档案已完成扫描与索引编制，可供科研界、教育工作者及普通公众免费检索下载。 该馆藏同时包含“地球之美（Earth As Art）”1、2、3系列馆藏、Landsat（陆地卫星）州域镶嵌图以及州域高程镶嵌图。每一幅公共事务办公室的影像都承载着独特的故事：从自然灾害纪实、地球现象的自然之美，到全球范围内河流、湖泊、海洋、山脉与冰山的独特观测视角。“地球之美（Earth As Art）”系列馆藏旨在展现影像的美学价值，而非进行科学解读——相关链接：http://eros.usgs.gov/imagegallery。 随着“本周影像（Image of the Week）”系列数据集的加入，以及更多胶片影像的扫描归档以供数据获取，公共事务办公室影像图库的馆藏规模将持续扩充。“本周影像”系列海报均为科学观测成果，着重展示当前水资源与土地覆盖的现状及其随时间的变化——相关链接：http://eros.usgs.gov/imagegallery/image-week-2。用户可获取TIFF（标记图像文件格式，Tagged Image File Format）格式的下载资源。 该馆藏已确定影像的近似坐标，但所有影像均未进行地理配准，且未提供地图投影或基准面相关信息。
