摘要:

准确及时的农情信息是国家与地方政府保障粮食安全与社会稳定的必要条件.云计算的出现为这一需求的实现提供了契机.本文阐述了农情遥感监测云服务平台建设的重要意义、设计思想、总体架构、组成部分以及建设内容.在此基础上,以农情遥感监测产品信息服务为例,开发了一个农情遥感监测信息在线原型系统.该系统是农情遥感监测云服务平台的重要组成部分,负责多尺度时间序列农情遥感监测结果与信息的管理、存储和维护,并且向用户提供查询与下载服务.农情遥感监测云服务平台建设框架的设计为全面整合专家智慧、IT技术、数据资源、服务方式以及平台的实现提供理论指导与建设依据.该平台的建立,将深刻改变农情遥感应用的模式,推动农情遥感的广泛应用与产业化发展.

Design framework for CropWatch Cloud
Abstract:

Accurate and timely information on crops is essential for national and regional food security, market planning, and social stability. All stakeholders (e.g., decision makers, traders, farmers) need reliable and up-to-date crop monitoring information whenever and wherever possible. A comprehensive online platform for global crop monitoring ought to be established to provide customers with a variety of real-time, easily accessible, and efficient services, such as raw data, information, maps, and analytical tools. The emergence of cloud computing provides a good opportunity to build such a global crop monitoring instrument. After a detailed inventory of the status, scope, and technological basis of existing cloud and remote sensing-based global crop monitoring systems, this study focuses on the relevance of CropWatch Cloud. The basic design concept, design framework, and main contents of CropWatch Cloud service platform are described, which will incorporate expert knowledge, advanced IT technology, and data resources. A virtuous cycle will be built to bridge science, technology, services, and applications. A prototype of CropWatch online was developed; users can query and download time series of crop monitoring indicators at different scales. The prototype of CropWatch online is an important part of CropWatch Cloud; it provides a downloading service for crop information, also stores and manages a long-term series of crop monitoring data and results. The evolvement of a local crop monitoring application into a convenient web-based application with multiple-terminal support is the key of the CropWatch Cloud project. The developed design framework will provide theoretical guidance and a sound basis for the construction of the CropWatch Cloud service platform. This platform will change the application patterns and promote the industrialization of agricultural remote sensing monitoring.
