摘要
网络地图提供了丰富的地理空间数据资源,本文以沈阳市主城区为例,以百度地图为底图,借助百度地图丰富的API,获取沈阳市行政区划矢量数据及兴趣点数据。采用开源的Openlayers,开发了“学校”兴趣点的热点图WEB页面,分析了沈阳主城区学校的空间分布规律和热点图的特点。并简介了ECharts可视化技术,初步探讨了其与Openlayers结合开发专题图WEB页面的传统开发方式,本文也为地理空间数据的获取、分析及可视化,提供了一种思路和方法。
The network map provides a wealth of geospatial data resources. This article takes the main city of Shenyang as an example. Taking Baidu map as the base map, the Baidu map rich API is used to obtain the administrative divisional vector data and interest point data of Shenyang City. Using the open source Openlayers, the WEB page of the “school” point of interest is developed, and the spatial distribution of the school in Shenyang main city and the characteristics of the hot map are analyzed. The ECharts visualization technology is introduced, and the traditional development method of WEB page with the development of the thematic map is discussed. This paper also provides a way of idea and method for the acquisition, analysis and visualization of geospatial data.
