Barrow Area Information Database (BAID) Geospatial Data Sets, Barrow, AK, USA

The Barrow Area Information Database (BAID) data collection is comprised of geospatial data for the research hubs of Barrow, Atqasuk and Ivotuk on Alaska's North Slope. Over 9600 research plots and instrument locations are included in the BAID research sites database. Updates to the project tracking database are ongoing through field mapping of new research locations and extant sampling sites dating back to the 1940s. Many ancillary data layers are also compiled to facilitate research activities and science communication. These geospatial data sets have been compiled through BAID and related NSF efforts. Geospatial data unique to this project are currently browseable via the BAID archive and include shapefiles of research information (sampling sites and instrumentation, the NOAA-CMDL clean air sector), administrative units (Barrow Environmental Observatory Science Research District plus adjacent federal lands, village districts, zoning, tax parcels, and the Ukpeagvik Inupiat Corporation boundary), infrastructure (power poles, snow fences, roads), erosion data for Elson Lagoon and imagery (declassified military imagery, air photo mosaics, IKONOS, Landsat, Quickbird, SAR and flight line indexes). Related data sets can be browsed via BAID’s web mapping tools and downloaded via the “Related links” section below. In addition, the BAID Internet Map Server (BAID-IMS) provides browse access to a number of additional layers which are available for download through catalog pages at the National Snow and Ice Data Center (NSIDC), the Alaska Geospatial Data Clearinghouse at USGS and the Alaska State Geo-Spatial Data Clearinghouse. Some layers are proprietary and are only available for browse access in BAID-IMS through special agreement. BAID provides a suite of user interfaces (Internet Map Server, Google Earth and Adobe Flex) and Open Geospatial Consortium web services for accessing the research plots and instrument locations. For more information on these tools, visit the BAID homepage in the links section below. BAID is a collaborative development effort between the Systems Ecology Lab at the University of Texas at El Paso and Nuna Technologies. BAID is funded by the National Science Foundation Office of Polar Programs Arctic Sciences Division (OPP 0454996.) BAID was initiated as a prototype through the Federal Geographic Data Committee's Cooperative Agreement Program (USGS Award: 03HQAG0177) via a grant to the Barrow Arctic Science Consortium to initiate the Barrow Area Spatial Data Infrastructure (SDI).巴罗地区信息数据库（Barrow Area Information Database, BAID）数据集合集收录了阿拉斯加北坡地区巴罗、阿塔苏克（Atqasuk）和伊沃图克（Ivotuk）三处研究枢纽的地理空间数据。该BAID研究站点数据库涵盖超过9600个研究样地与仪器部署点位。项目跟踪数据库的更新工作目前仍在进行中，通过对新研究点位以及可追溯至20世纪40年代的现存采样点开展野外测绘完成更新。此外，数据库还整合了诸多辅助数据图层，以助力研究活动开展与科学传播。上述地理空间数据集均由BAID及相关美国国家科学基金会（National Science Foundation, NSF）项目团队整合完成。本项目专属的地理空间数据目前可通过BAID档案库浏览，其涵盖研究信息形状文件（包含采样点位、仪器部署以及美国国家海洋和大气管理局气候监测与诊断实验室（NOAA-CMDL）清洁空气监测分区）、行政边界图层（包括巴罗环境观测站科学研究区及毗邻联邦土地、村落辖区、分区规划、税籍地块，以及乌克佩阿格维克伊努皮亚特公司（Ukpeagvik Inupiat Corporation）管辖边界）、基础设施图层（含电线杆、防雪栅栏、道路）、埃尔森泻湖侵蚀数据以及多类影像数据（包括解密军事影像、航空影像镶嵌图、IKONOS影像、Landsat影像、Quickbird影像、合成孔径雷达（Synthetic Aperture Radar, SAR）数据与飞行航线索引）。相关数据集可通过BAID的网页地图工具浏览，并可通过下方"相关链接"板块下载。此外，BAID互联网地图服务器（BAID-IMS）提供了诸多额外数据图层的浏览权限，这些图层可通过美国国家雪冰数据中心（National Snow and Ice Data Center, NSIDC）、美国地质调查局（United States Geological Survey, USGS）下属的阿拉斯加地理空间数据交换所以及阿拉斯加州地理空间数据交换中心的目录页面下载。部分图层为专有数据，仅可通过特殊协议在BAID-IMS中进行浏览。BAID提供了一套完整的用户交互界面（含互联网地图服务器、谷歌地球（Google Earth）与Adobe Flex平台）以及开放地理空间信息联盟（Open Geospatial Consortium, OGC）网络服务，用于访问研究样地与仪器部署点位。如需了解上述工具的更多详情，请访问下方链接板块中的BAID官方主页。BAID由德克萨斯大学埃尔帕索分校系统生态学实验室与努纳科技（Nuna Technologies）合作开发。该项目由美国国家科学基金会极地项目办公室北极科学部资助（项目编号：OPP 0454996）。BAID最初作为原型项目，通过联邦地理数据委员会合作协议项目（美国地质调查局资助编号：03HQAG0177），向巴罗北极科学联盟提供拨款以启动巴罗地区空间数据基础设施（Spatial Data Infrastructure, SDI）建设。
