【摘要】：随着智能移动终端设备在普通大众生活中的普及，以移动终端为平台的环境星遥感数据共享受到越来越多的关注。环境星遥感产品数据由遥感算法和遥感影像数据经过遥感产品生产过程产生，在传统的遥感数据共享方式中，这一动态生产过程发生在用户提交共享请求之前，这种方式带来的问题是用户请求共享的产品数据缺少自主选择性及获得的产品数据类型有限。针对该问题，论文采用遥感数据处理系统作为遥感产品数据生产的支撑平台，，提出一种数据共享机制模型，并对模型的数据结构及对应操作进行设计，来提高遥感数据共享的灵活性和动态性。本文的主要工作如下：（1）改进遥感数据处理系统的接口：已存在的遥感数据处理系统自动化处理能力弱、操作复杂，非人工干预下不能进行自动化的遥感产品数据的动态生产。通过对数据处理系统消息接口的改进，使处理系统融入一个应用技术中心加多个行业这种环境应用模式中，同时为遥感产品数据的生产提供核心支撑。（2）设计数据共享机制模型的结构和操作：对提出的遥感数据共享机制，从数据结构和操作两个方面分别进行设计，以满足移动终端平台下环境星遥感数据共享的实际需求。（3）验证共享机制的可行性：在作者参与的国家重大专项课题集成与共享原型系统中，实现了本文提出的共享机制，通过实际的部署运行验证在移动终端下访问系统提供的数据共享服务的可行性。从系统的响应时间、得出的遥感数据精度等方面来分析实验结果，该系统提供的共享服务能满足现阶段下用户的共享需求，从而验证该共享机制实际可行。
[Abstract]:With the popularity of intelligent mobile terminal devices in the general public life, more and more attention has been paid to the sharing of remote sensing data from environmental stars based on mobile terminals. The environmental star remote sensing product data is generated by remote sensing algorithm and remote sensing image data through the remote sensing product production process. In the traditional remote sensing data sharing mode, this dynamic production process occurs before the user submits the sharing request. The problem caused by this approach is that the product data requested by users is lack of independent selectivity and the types of product data obtained are limited. In order to solve this problem, this paper uses remote sensing data processing system as the supporting platform of remote sensing product data production, proposes a data sharing mechanism model, and designs the data structure and corresponding operation of the model. To improve the flexibility and dynamics of remote sensing data sharing. The main work of this paper is as follows: (1) improving the interface of remote sensing data processing system: the existing remote sensing data processing system has weak automatic processing ability and complex operation. The dynamic production of automatic remote sensing product data can not be carried out without manual intervention. Through the improvement of the message interface of the data processing system, the processing system is integrated into the environmental application mode of one application technology center and more than one industry, and provides the core support for the production of remote sensing product data at the same time. (2) Design the structure and operation of the data sharing mechanism model: the proposed remote sensing data sharing mechanism is designed from two aspects of data structure and operation to meet the actual needs of remote sensing data sharing of environmental stars under the mobile terminal platform. (3) to verify the feasibility of the sharing mechanism: the sharing mechanism proposed in this paper is realized in the integration and sharing prototype system of the national major special project in which the author participates. The feasibility of accessing the data sharing service provided by the system under the mobile terminal is verified by the actual deployment and operation. The experimental results are analyzed from the aspects of the response time of the system and the accuracy of remote sensing data. The sharing service provided by the system can meet the sharing needs of users at the present stage, thus verifying the practical feasibility of the sharing mechanism.
