0422611 Kusky描述：该奖项是为了支持合作研究博士蒂莫西M。密苏里州圣刘易斯的圣刘易斯大学地球科学系的Kusky博士和Talaat M. Ramadan，埃及开罗国家遥感和空间科学管理局地质系。 轨道遥感技术已发展到实际应用的先进水平，特别是在光学和雷达成像方面。 轨道光学成像可用于绘制岩性详细图和查明矿藏。 成像雷达在绘制构造图以及估计表面粗糙度方面很有用，表面粗糙度可用于识别岩性。 计划在今后几年内安装新的轨道传感器，以获得更好的光谱和空间分辨率以及新的数据。 此外，最近航天飞机雷达地形使命（SRTM）的数据成功地利用C波段（6厘米波长）雷达对北纬60度至南纬60度之间的地球表面地形进行了成像和测绘。 这些数据对于确定活跃的构造和地貌特征以及监测地质灾害和环境变化将具有独特的强大功能。 在这项研究中，我们提出了一些利用卫星图像与新的，潜在的更强大的遥感技术和更高分辨率的主动传感器SAR图像来描绘结构，以了解构造演化和地震活跃的埃尔-法尤姆凹陷内的危险。 制作的地图将允许研究正在考虑开发项目的地区，并勘探西部沙漠尚未勘探的地区。 项目研究所在对非洲东北部、阿拉伯、马达加斯加、中国和其他干旱地区进行地质研究以及利用轨道遥感数据解决干旱地区地质问题方面具有经验。 Kusky博士和Ramadan博士参加了1998年2月22日至28日在开罗举行的美国-埃及沙漠研究优先事项讲习班，并在此之后共同发表了几篇关于利用遥感技术进行地质应用的论文，并完成了对El-Fayum地区的遥感勘测研究。范围和广泛影响：来自美国和埃及的高级科学家将与埃及的初级科学家以及美国和埃及的学生合作，将现有的遥感和实地技术与开发新技术相结合，以整合地质和灾害评估的不同数据类型。 在过去，这个团队已经开发了新的卫星图像分析技术，用于矿产资源和地下水勘探，现在他们将集中精力进行地质灾害评估，土地利用，开发和构造演化。 了解这一发展中地区的地质灾害将对当地居民大有用处，灾害监测和地质研究新技术的发展将对社会有更广泛的用处。 该项目涉及美国和埃及的大学，政府组织和科学家，从高级教师到本科生实验室助理。该项目得到了美国-埃及联合基金方案的支持，该方案向两国的科学家和工程师提供赠款，以开展这些合作活动。

0422611KuskyDescription: This award is to support cooperative research between Dr. Timothy M. Kusky, Department of Earth Sciences, Saint Louis University, Saint Louis, Missouri and Dr. Talaat M. Ramadan, Department of Geology, National Authority for Remote Sensing and Space Sciences (NARSS), Cairo, Egypt. Orbital remote sensing technology has progressed to advanced levels of practical application, particularly with respect to optical and radar imagery. Orbital optical imagery can be utilized to map lithological details as well as for identifying mineral deposits. Imaging radar is useful in mapping structures as well as estimating surface roughness, which can be used to identify lithology. New orbital sensors are planned for the next few years to obtain better spectral and spatial resolution and new data. In addition, recent data from the Shuttle Radar Topographic Mission (SRTM) has successfully imaged and mapped the topography of the Earth's surface between 60'N and 60'S using C-band (6 cm wavelength) radar. These data will be uniquely powerful for characterizing active tectonic and geomorphological features, and for monitoring geological hazards and environmental changes. In this study we propose to link some methods of utilizing satellite imagery with new, potentially more powerful remote sensing techniques and higher resolution active sensor SAR images to delineate structures in order to understand the tectonic evolution and hazards within the seismically active El-Fayum Depression. The produced maps will allow study of areas being considered for development projects and exploration of the yet unexplored tracts of the Western Desert. The PI has experience in geologic studies on NE Africa, Arabia, Madagascar, China, and other arid regions, and in using orbital remote sensing data to solve geologic problems in arid regions. Dr. Kusky and Dr. Ramadan attended a US-Egypt Workshop on Priorities of Desert Studies, held in Cairo from Feb. 22-28, 1998, and have since published several papers together on utilizing remote sensing techniques for geological applications, and have completed a reconnaissance remote sensing study of El-Fayum area. Scope and broad impact: Senior scientists from the US and Egypt will be working with Junior Egyptian scientists and with US and Egyptian students, integrating existing remote sensing and field techniques with the development of new techniques for integrating different data types for geological and hazards assessments. In the past, this team has derived new satellite image analysis techniques for mineral resource and ground water exploration, and now they will focus their efforts on geologic hazards assessment, land use, development, and tectonic evolution. Understanding the geological hazards in this developing area will be of great use to the local population, and the development of new techniques for hazards monitoring and geologic studies will be of broader use to society. The project involves US and Egyptian Universities, governments' organizations, and scientists ranging from senior faculty to undergraduate lab assistants. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
