基于适配器原理的异构地理信息数据服务集成方法与实验

Heterogeneous Geographic Information Data Service Integration Method and Experiment Based on Adapter Principle

主要研究了异构地理信息服务集成方面的问题,探讨了基于适配器原理的异构服务集成的可行性。通过实验将切片服务、ArcGIS Server以及Erdas Apollo发布的WMS 3种异构服务集成到一起,形成一个新的、面向专题的地图服务,并与基于API的异构服务集成方法进行对比分析。该研究具有重要理论价值和实际意义,研究结果为大数据时代分布的地理空间信息服务高效集成、实现功能更加完善的Web GIS以及Web环境下在线地理空间信息应用提供一种可行的、现实的方法。

This paper mainly studies the integration of heterogeneous geographic information services,discusses the feasibility of integration of heterogeneous services based on adapter principle,and integrates slice services,ArcGIS Server and WMS released by Erdas Apollo into a new,thematic-oriented map service through experiments.The method of heterogeneous service integration based on API is compared and analyzed.This research has important theoretical and practical significance.The research results provide a feasible and realistic method for the efficient integration of geospatial information services distributed in the era of big data,the realization of Web GIS with more perfect functions and the application of online geospatial information under the Web environment.
