The Polar Geospatial Information Center: Joint Support

知识价值：PI建议扩展南极地理空间信息中心（AGIC）的现有活动，将北极活动也包括在内。极地地理空间信息中心（PGIC）将为两极的科学和业务活动提供地理空间支持，同时还提供对新数据源的访问。AGIC拥有现有的基础设施，经验丰富的工作人员，并与国家地理空间情报局（NGA）建立了工作关系，可以有效地扩展以支持美国的北极研究计划。PGIC将为极地科学和业务社区提供三个重要功能：为资助的研究提案获取南极和北极的亚米高分辨率卫星图像以及后勤支持；从这些图像和其他地理空间数据中处理、分析和创建产品的专业知识；开发短期课程，教授地理空间技术和可视化软件的使用。支持北极和南极活动的基础将是亚米分辨率卫星图像的马赛克：极地高分辨率商业图像集（HIPOLE）。虽然北极和南极的大部分地区都有地图和地理空间数据，但由于缺乏使用必要工具或数据集的经验，这些地理信息系统数据的使用往往受到阻碍。PGIC将通过为美国极地研究人员提供地理信息系统和遥感方法研讨会和指导，以及专业知识和独特数据集的访问来解决这一问题。更广泛的影响：这项活动将为极地社区提供高分辨率地理空间数据，将为其分析提供专业知识，将培训研究人员使用这些数据，并将传播研究人员的地理空间产品。

Intellectual Merit: The PI proposes to extend existing activities of the Antarctic Geospatial Information Center (AGIC) to also include Arctic activities. The Polar Geospatial Information Center (PGIC) will provide geospatial support for science and operational activities at both poles while also providing access to new data sources. AGIC has an existing infrastructure, experienced staff, and a working relationship with the National Geospatial Intelligence Agency (NGA) that can be efficiently expanded to support the U.S. Arctic Research Program. PGIC will provide three important functions for the polar science and operations communities: access to sub-meter, high-resolution satellite imagery for the Antarctic and Arctic for funded research proposals as well as logistics support; expertise to process, analyze, and create products from this imagery and other geospatial data; and development of short courses to teach geospatial techniques and use of visualization software. The foundation to support Arctic and Antarctic activities will be a mosaic of sub-meter resolution satellite images: High-Resolution Commercial Imagery Collection of the Poles (HIPOLE). While maps and geospatial data exist for much of the Arctic and Antarctic, use of these GIS data is often hindered by a lack of experience with necessary tools or datasets. PGIC would address this issue by providing GIS and remote sensing methodology workshops and guidance to U.S. polar researchers, along with expertise and access to unique datasets. Broader impacts: This activity will support a broad segment of the polar community with a high-resolution geospatial data, will provide expertise to aid in its analysis, will train researchers in its use and, will disseminate the geospatial products of researchers.
