The growing number of Earth observation satellites are producing exponential increases in the amount of data produced. These data sets contain valuable information on the state of the environment to accurately monitor and predict the impact of global change. Global change investigations require access to long-term data. This paper is a review of the current archiving practices of NOAA, NASA, SPOT, ESA and the DLR. It is demonstrated that despite recognition at a regional and organisational level of the importance of data archiving much work remains to be done. Funding responsibility is identified as a particularly problematic area of data archiving: it is an issue along with the need for easy accessibility and adequate metadata that will need to be resolved to ensure that future generations have access to adequate Earth observation data archives. 相似文献

China will launch 6 more Earth observation satellites in the next five years including CBERS-02B, 03, 04 satellites and EDMC constellation satellites A, B and C. A complete national Earth observation system will be established after the successful launch and operation of the above satellites. The information was released by China Center for Resource I Satellite Data and Applications (CRESDA) recently. 相似文献

为确保高层建筑物的安全性和正常使用寿命,避免因建筑物发生沉降造成主体结构的破坏或出现影响结构使用功能的裂缝,在施工过程中必须对高层建筑物进行沉降观测。本文以某小区的高层建筑物为实例,首先介绍了进行沉降观测时基准点和观测点的基本布设方案与原则,其次讲述了进行沉降观测的施测精度和方法,最后对其观测的成果进行了数据的处理与分析。 相似文献

At the Earth Observation Summit in 2003 at the US Department of State, environmental ministers from more than 30 countries joined three US cabinet secretaries to plan the creation of a system for international sharing of data about the atmosphere, the oceans and the land. The meeting grew in part out of commitments by leaders at a G-8 summit meeting in France to build an integrated global earth environmental monitoring system. Opportunities and problems both figure prominently in implementation of the Summit's vision. The challenges include who pays for infrastructure, training, and administration; whether to control data access; how to include the private sector; and whether problems of collective action will plague the effort. 相似文献

全球高分光学星概述(二):欧洲 总被引:1,自引:0,他引:1
《航天器工程》2016,(1):95-118
欧洲高分光学星及其星座主要以欧洲航天局(ESA)和法国、英国、德国、西班牙、意大利等国家研制的卫星为主。法国牵头的军事卫星太阳神-2(Helios-2)地面分辨率(全色)为0.35m;商业遥感卫星主要有法国的SPOT-6/7和昴宿星(Pleiades)星座(分辨率0.5m)以及英国主导的灾害监测星座(DMC)(分辨率可达1m)。亚米级彩色视频成像小卫星正在研制之中。6U立方星星座及米级地球静止轨道光学星等新概念已被提出。地球静止轨道光学星由ESA牵头,应用传统相机地面分辨率可达3m,而未来的概念(光学合成孔径)可使分辨率优于3m。文章着重阐述欧洲地球观测高分光学星的应用、技术状态与发展趋势。 相似文献

Over the next decade, a Global Earth Observation System of Systems (GEOSS) will revolutionize our understanding of the Earth and how it works, producing societal benefits through more coordinated observations, better data management, increased data sharing and timely applications. The political momentum behind the establishment of GEOSS is described and examples of its benefits—drought prediction, disease monitoring, accuracy of weather and energy needs forecasting, disaster mitigation—are provided. While challenges exist, particularly in the area of making data accessible, steps are being taken to meet them, e.g. through the new GEO-Netcast concept. Interagency collaboration within countries is as important as international cooperation; the efforts of the US Group on Earth Observations in this regard are discussed. Maintaining the strong political support here and in all participating countries will be key to the success of GEOSS. 相似文献

The world's first political summit on Earth observation was attended by senior policy makers and expert organizations from a range of scientific disciplines. Its aim was to improve global cooperation in Earth observation and increase its use as a decision-making tool for sustainable development and resource conservation. This article presents a brief survey of the progress made in Earth observation since its birth, along with the specific events driving the convening of the summit. The summit produced a declaration outlining four key areas requiring support, and an ad hoc group was established to produce a 10-year plan and drive implementation of policy. 相似文献
