This project acquires a Terrestrial Laser Scanner (TLS) system designed for use in the extreme cold of the Earth's polar regions. TLS technology is based on Light Distance and Ranging (LiDAR). It generates high resolution, three-dimensional maps of surfaces and objects over scales of meters to kilometers with sub-centimeter precision. Beyond imaging, the high precision allows the detection and quantification of minute changes in surface elevation and shape. In terms of intellectual merit, the system will be used for a range of polar projects including glacier movement, deformation of frozen ground, magma lake dynamics, and characterization of environments hosting life. The unique capability and ease of deployment make TLS a useful complement to other imaging techniques employed in polar regions such as Synthetic Aperture Radar, and airborne and spaceborne LiDAR. In terms of broader impacts, this project represents new research infrastructure for polar work. The instruments will be acquired and managed by UNAVCO, the university consortium for GPS and terrestrial LIDAR, and will be made available to the general scientific community. The instruments will see immediate use during the 2007-2009 International Polar Year (IPY). This project also meets the IPY goal of leaving a legacy of new technology for polar observations.

该项目获得了一个地面激光扫描仪（TLS）系统，该系统是为在地球极寒的极地地区使用而设计的。TLS技术基于光距离和测距（LiDAR）。它能以亚厘米的精度生成高分辨率的物体和表面的三维地图，范围从米到公里。除了成像，高精度可以检测和量化表面高程和形状的微小变化。就智力价值而言，该系统将用于一系列极地项目，包括冰川运动、冻土变形、岩浆湖动力学和承载生命的环境特征。独特的能力和易于部署使TLS成为极地地区使用的其他成像技术（如合成孔径雷达、机载和星载激光雷达）的有用补充。就更广泛的影响而言，该项目代表了极地工作的新研究基础设施。这些仪器将由联阿援助团、全球定位系统和地面激光雷达大学联盟获得和管理，并将提供给整个科学界。这些仪器将在2007-2009国际极地年（IPY）期间立即投入使用。该项目也符合国际极地年为极地观测留下新技术遗产的目标。
