【摘要】：隨著智能移動終端設(shè)備在普通大眾生活中的普及，以移動終端為平臺的環(huán)境星遙感數(shù)據(jù)共享受到越來越多的關(guān)注。 環(huán)境星遙感產(chǎn)品數(shù)據(jù)由遙感算法和遙感影像數(shù)據(jù)經(jīng)過遙感產(chǎn)品生產(chǎn)過程產(chǎn)生，在傳統(tǒng)的遙感數(shù)據(jù)共享方式中，這一動態(tài)生產(chǎn)過程發(fā)生在用戶提交共享請求之前，這種方式帶來的問題是用戶請求共享的產(chǎn)品數(shù)據(jù)缺少自主選擇性及獲得的產(chǎn)品數(shù)據(jù)類型有限。針對該問題，論文采用遙感數(shù)據(jù)處理系統(tǒng)作為遙感產(chǎn)品數(shù)據(jù)生產(chǎn)的支撐平臺，，提出一種數(shù)據(jù)共享機(jī)制模型，并對模型的數(shù)據(jù)結(jié)構(gòu)及對應(yīng)操作進(jìn)行設(shè)計(jì)，來提高遙感數(shù)據(jù)共享的靈活性和動態(tài)性。 本文的主要工作如下： （1）改進(jìn)遙感數(shù)據(jù)處理系統(tǒng)的接口：已存在的遙感數(shù)據(jù)處理系統(tǒng)自動化處理能力弱、操作復(fù)雜，非人工干預(yù)下不能進(jìn)行自動化的遙感產(chǎn)品數(shù)據(jù)的動態(tài)生產(chǎn)。通過對數(shù)據(jù)處理系統(tǒng)消息接口的改進(jìn)，使處理系統(tǒng)融入一個(gè)應(yīng)用技術(shù)中心加多個(gè)行業(yè)這種環(huán)境應(yīng)用模式中，同時(shí)為遙感產(chǎn)品數(shù)據(jù)的生產(chǎn)提供核心支撐。 （2）設(shè)計(jì)數(shù)據(jù)共享機(jī)制模型的結(jié)構(gòu)和操作：對提出的遙感數(shù)據(jù)共享機(jī)制，從數(shù)據(jù)結(jié)構(gòu)和操作兩個(gè)方面分別進(jìn)行設(shè)計(jì)，以滿足移動終端平臺下環(huán)境星遙感數(shù)據(jù)共享的實(shí)際需求。 （3）驗(yàn)證共享機(jī)制的可行性：在作者參與的國家重大專項(xiàng)課題集成與共享原型系統(tǒng)中，實(shí)現(xiàn)了本文提出的共享機(jī)制，通過實(shí)際的部署運(yùn)行驗(yàn)證在移動終端下訪問系統(tǒng)提供的數(shù)據(jù)共享服務(wù)的可行性。從系統(tǒng)的響應(yīng)時(shí)間、得出的遙感數(shù)據(jù)精度等方面來分析實(shí)驗(yàn)結(jié)果，該系統(tǒng)提供的共享服務(wù)能滿足現(xiàn)階段下用戶的共享需求，從而驗(yàn)證該共享機(jī)制實(shí)際可行。
[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.
