基于Web Map服务的空间信息集成模型及其在农业信息集成中的应用

摘要

本文通过对空间数据交换技术的分析研究,设计了1个基于Web Map服务的农业空间信息集成模型,并详细介绍了模型的功能结构.模型实现采用KML作为信息交换载体,集成双方依据约定的KML Schema提取空间信息,并产生对应的KML 文档完成数据集成.%With the analysis of spatial data switching technology, a Web Map service based agricultural spatial information integration model was designed and the function architecture of the model was introduced in detail in the paper. The model was realized by using KML as the carrier of message, according to the KML Schema agreed on, Both sides of the system integrate data with the corresponding KML documents.
