美国NASA建设地球观测科学数据产品生成与应用服务的量化体系综述

为了回答美国国会对NASA科研投入效益的咨询,NASA选择了美国地球观测计划中的科学观测计划，以此作为国家资金投入项目的效益量化与评价体系的示范，这对NASA的遥感探测信息定量化处理与建立用户的信息推广服务体系都产生了重要的影响。介绍该项目实现量化的技术体系和管理,对于目前我国正要建设的高分辨率对地观测体系，以及正在经历的从定性向定量应用的转变，这些经验都具有一定的参考价值。

The Introduction of Quantity Development of NASA Earth Observation Science Data Product and Its Services

In order to answer the question from the United State congress on the investment and effects based on the Government Performance Results Act of 1993.NASA selected earth science program-ESE of EOS earth observation plan as an example to demonstrate the government's investment and effects quantity evaluation.This demonstration will have long term effect on the earth observation data processing and service through the bridge of quantity index system.In this paper,we introduce the objectives and contents of the program with a view of borrowing the good experience for carrying out the program of high resolution earth observation system in China,and also for current application experiencing the transformation to quantification applications.
