摘要
随着室内地理信息系统(geographic information systems,GIS)的蓬勃发展,如何在线实现室内平面图的配准已成为一个急需解决的问题。目前,支持地理配准功能的GIS软件基本都只提供桌面端服务,鲜有基于网页端开发的在线配准工具。本文提出了一种室内平面图的在线配准方法,给出了室内平面图在线配准方法的基本流程。用户将室内平面图加载至地图上之后,可通过平移、旋转、缩放地图或室内平面图,使室内平面图与地图上的轮廓吻合,达到地理配准的目的。在此基础上,用户可以进行在线矢量化,并可将矢量化数据导出为GeoJSON数据。该方法已在室内三维地理信息系统研发中得到成功应用。
With the rapid development of indoor geographic information systems(GIS),how to achieve georeferencing of indoor floor plans online has become an urgent problem to be solved.At present,GIS software supporting georeferencing functions only basically provides desktop services,and there are few online georeferencing tools developed based on web.This paper proposes an online georeferencing method for indoor floor plan,and gives the basic flow of the online georeferencing method for indoor floor plan.After the user loads the indoor floor plan onto the map,the indoor floor plan can be matched with the outline on the map by panning,rotating,zooming the map or the indoor floor plan to achieve the purpose of georeferencing.Based on this,users can perform online vectorization and export vectorized data to GeoJSON data.This method had been successfully applied in the development of indoor 3D geographic information systems.
