Antarctic Mapping and Geodesy

马林斯和WitmerOPP 9817876摘要该奖项由南极地质和地球物理计划以及极地计划办公室的南极生物和医学计划提供，支持美国南极研究计划的测绘、测量、卫星图像和大地测量活动。大地测量、航空摄影、遥感(主要使用几种卫星图像)和测绘包括在南极洲成功开展多方面科学和探索工作所必需的各种活动。全年的数据获取、编目和数据传播活动将继续在美国南极资源中心进行，以获取地理空间信息。将进行实地调查，以支持具体的研究项目，并作为收集地面控制数据的持续方案的一部分，以便将现有的大地测量数据转换为适合未来卫星测绘方案的以地球为中心的系统。将收集陆地卫星数据，作为卫星图像测绘活动的一部分，并将继续在干旱河谷地区出版另外1：50 000比例尺的地形图。地形图提供了一个底图，可以在其上以空间精确的方式描绘科学信息，如地质、冰川和生物信息，以供分析。科学家还将使用这些地图和卫星图像地图来规划和执行未来的研究工作。在空间参考方面，数字制图数据将与出版的地图同步编制。

Mullins and WitmerOPP 9817876AbstractThis award, provided by the Antarctic Geology and Geophysics Program and the Antarctic Biology and Medicine Program of the Office of Polar Programs, supports mapping, surveying, satellite imagery, and geodetic activities in support of the US Antarctic Research Program. Geodetic surveying, aerial photography, remote sensing (principally using several varieties of satellite imagery), and mapping comprise a variety of activities necessary for the successful operation of a multifaceted scientific and exploration effort in Antarctica. Year-round data acquisition, cataloging, and data dissemination activities will continue in the US Antarctic Resource Center for geospatial information. Field surveys will be conducted both in support of specific research projects and as part of a continuing program to collect ground control data required to transform existing geodetic data to an earth-centered system suitable for future satellite mapping programs. LandSat data will be collected as part of satellite image mapping activities and publication of additional 1:50,000 scale topographic maps in the Dry Valleys region will continue. The topographic maps provide a base map on which to portray scientific information, such as geological, glaciological, and biological information in a spatially accurate manner for analysis. The maps and satellite image maps will also be used by scientists to plan and execute future research work. Spatially references digital cartographic data will be produced in tandem with the published maps.
