Applications of Historical and Recent Satellite Data Sets for Geophysical Studies of the Modern Greenland Ice Sheet

首席调查员将汇编1960年代初在格陵兰冰盖上获得的历史卫星数据的数字马赛克。这些数据是作为Argon项目的一部分获得的，最近被解密，供科学界使用。它们适用于地球偏远地区，特别是极地地区的地质和冰川学研究。他们将尝试获取格陵兰岛1962-1964年间收集的所有历史卫星图像。他们将利用卫星位置、可用的数字高程模型(DEM)和可用的地面控制知识对每一幅图像进行正射纠正。至少两个覆盖整个格陵兰岛的数字马赛克将从正射校正的数据中编辑出来。马赛克将作为CDROM分发给其他用户。将通过基于网络的目录和浏览器访问个别矫正器。完成的马赛克将相互比较，并与最近编制的格陵兰图像地图进行比较。这一结果将用于研究冰盖边缘、沿海冰川崩解锋面、冰盖运动和动力学的变化。

The Principal Investigators will compile digital mosaics of historical satellite data acquired during the early 1960s over the Greenland Ice Sheet. These data were acquired as part of the Argon project and were recently declassifed for use by the science community. They are applicable to geological and glaciological studies of remote parts of the Earth and particularly to the polar regions. They will attempt to acquire all historical satellite imagery collected over Greenland from 1962-1964. They will orthorectify each image using knowledge of the satellite position, available Digital Elevation Model (DEMS), and available ground control. At least two digital mosaics covering all of Greenland will be compiled from the orthorectified data. The mosaic will be distributed to other users as a CDROM. Access to individual orthorectified will be made through a web-based catalogue and browser. The completed mosaics will be compared to each other and to more recently compiled image maps of Greenland. The result will be used to study changes in the ice sheet margin, calving front of coastal glaciers, ice sheet motion and dynamics.
