一种城市通行空间内混合路径分析模型研究

Research on hybrid path analysis model in urban accessible space

提出一种基于WebGIS的城市通行空间内混合路径分析服务的模型,集成矢量数据、栅格数据和位置兴趣点等不同类型数据,结合网络路径分析和栅格路径计算,能够面向用户提供城市通行空间下完整路径服务。应用JavaScriptWeb技术和百度地图开放平台,在Web环境下实现混合路径分析与服务功能,验证模型的可行性。结果表明,相比于电子地图应用,混合路径分析能完整覆盖城市空间下通行过程,为提升城市路径分析服务质量提供有效地解决方案。

A hybrid path-analysis services model in urban accessible space is presented with WebGIS technology.Through integrating vector data, raster data and POI data, and using network path analysis and raster path calculation, this model can provide integrated path analysis services to users in urban.In order to test reasonability of model, a hybrid path analysis services function is implemented by using techniques of JavaScript Web and the Baidu Map Open API.Compared to internet map applications, the hybrid path analysis can realize analysis of integrated transit process in urban accessible space, which can offer an effective solution to improve quality of urban path analysis services.
