摘　　要：目前大部分房屋电子地图都是基于传统的基本地形图测绘、遥感影像判读和人工外业采集等方式实现数据更新,这些方式存在地图更新周期长、成本高、工作量大和地图现势性差,以及较难发现有变化的房屋要素等问题。本文提出了一种由房屋管理的以房屋测绘业务为驱动的主动式房屋电子地图快速更新模式,即以施工建设—房屋竣工—房屋测绘为主线,实现主动式房屋电子地图更新,从而获取房屋电子地图现状,并实现房屋空间信息与交易权属业务数据的自动关联。该方法较传统房屋电子地图更新方法具有更新周期短、成本低、数据准确性高和地图现势性强等优点。目前,该方法已经应用于房屋全生命周期平台中,高效地实现了房屋电子地图自动更新。At present,the updating method of housing digital map is mostly based on basic topographic mapping,remote sensing and on-field data gathering,etc.,which results in several problems such as long updating period,high costs,heavy workload,low timeliness and difficulties in change discovery. A fast updating method of housing digital map is presented,based on business data in related business process of city change,especially,spatial data of housing mapping,to require high timeliness of housing digital map,and to achieve automatic association of housing spatial information and housing transaction business data. Compared with traditional updating methods of housing digital map,this method has the characteristic of low cost,high accuracy,high timeliness. Presently,it has been applied into the construction of Beijing housing-life-cycle management information platform,and efficiently realized the automatic updating of housing digital map.
