高分遥感京津冀一体化服务平台设计与实现

Design and Implementation of Integration of Beijing-Tianjin-Hebei Service Platform Based On High Satellite Remote Sensing

摘要:

为实现国产高分卫星影像在京津冀区域省、市、县、乡多级行政结构的农业、林业和环境保护等领域的快速应用,设计开发了基于WebGIS的高分卫星遥感数据京津冀一体化服务平台。平台采用B/S系统架构设计,通过ArcGIS Server服务器,将ArcSDE空间数据库中的数据发布成动态图层服务,实现海量图层的动态调用。利用ASP.NET三层架构技术,结合SQL Server数据库和ArcGIS API for Javascript脚本,将ArcGIS Server提供的空间数据资源嵌入Web系统中,实现遥感专题信息产品空间信息和属性信息的资源整合以及数据查询功能,在解决海量数据传输问题的同时减轻了网络的负担。集成jQuery开源框架,融入Ajax技术,实现资源信息的可视化展示和按时间轴顺序的多期回顾。结合ECharts控件丰富的图表类型和直观、易用的交互方式,对展现的数据进行了挖掘、提取,进而转化成直观的图、表显示,实现遥感专题信息产品的统计分析及相关产品信息的输出功能。平台为京津冀一体化遥感应用提供了快速、科学的空间信息服务。

Abstract:

In order to realize the rapid application of domestic high satellite image in the fields of agriculture, forestry and environmental protection in the provincial, municipal, county and township administrative structures of Beijing, Tianjin and Hebei region, the high satellite remote sensing data service platform for the integration of Beijing-Tianjin-Hebei based on WebGIS is designed and developed. B/S system structure design is adopted in the platform completely and the data of the ArcSDE spatial database is published into the dynamic layer service through the ArcGIS Server server, and the dynamic call of the mass map is achieved. The spatial data resources provided by ArcGIS Server are embedded in the Web system and the system is achieved using the ASP.NET three-tier architecture technology, combining the SQL Server database and the ArcGIS API for Javascript, including the resources integration of the spatial information and attribute information of remote sensing thematic information products and the data query function,and the burden of network is lightened at the same time in solving the problem of bulk data transfer. With the integration of jQuery open source framework and Ajax technology, the visualization of resource information and multi-period review in chronological order are realized. Combining the rich chart type of ECharts and the interactive way of intuitionistic and easy to use, the data is excavated and extracted, and then transformed into an intuitionistic diagram and table to realize the statistical analysis of remote sensing thematic information products and the output function of related product information. The platform provides the rapid and scientific spatial information services for remote sensing application of the integration of Beijing-Tianjin-Hebei.
