遥感全景测绘大数据智能共享方法

Intelligent sharing method of big mapping data from panoramic remote sensing

目前应用的遥感全景测绘大数据共享方法存在共享效率低、稳定性差、在线预览效果不理想等弊端。为了解决上述问题,全面提升遥感全景测绘大数据共享效果和质量,本文研究了一种全新的遥感全景测绘大数据智能共享方法。通过结合遥感全景测绘技术概念的应用,以J2EE(Java 2 Platform Enterprise Edition)框架技术为基础,融合多种开源技术,构建了“数据-逻辑-表示”的三层遥感全景测绘数据共享模型。该模型的技术方面,采用缩略图叠加法将检索结果进行贴图预览,实现共享数据的可视化。试验结果表明,本文研究的遥感全景测绘大数据智能共享方法的数据共享速率为120 M/s,共享稳定系数约为0.3,数据共享能力更强,在线预览效果更优秀。

At present,the big mapping data sharing methods of panoramic remote sensing have such drawbacks as low sharing efficiency,poor stability and unsatisfactory online preview effect,etc..In order to solve the above problems,and comprehensively improve the sharing effect and quality of big mapping data from panoramic remote sensing,this paper introduces a new intelligent sharing method of big map⁃ping data from panoramic remote sensing.Based on J2EE framework technology and multiple open source technologies,a three-layered panoramic remote sensing mapping data sharing model of“data-logicrepresentation”is constructed by combining panoramic remote sensing technology.In the technical aspect of the model,the retrieval results are previewed by thumbnail superposition method to visualize the shared data.The experimental results show that the data sharing rate of the mentioned method in this paper is 120 M/s,the sharing stability coefficient is about 0.3,the data sharing ability is more robust,and the online preview effect is better.
