摘要
GIS技术是当前数字房产系统建设的支撑技术之一。GIS在数字房产系统中的应用,首先要解决房产分层分户平面图这一特殊的房产图形在2维GIS中的管理。本文提出了一种基于大二进制对象“图图分离、图属分离”的房产分层分户平面图管理的数据模型,并以杭州数字房产项目为例介绍了GIS在数字房产系统中的应用。
GIS technology is one of the key technologies used in building up Digital Real Estate System ( DRES ). When we use GIS in DRES, we must firstly solve the problem of managing floor & house map data model in 2D GIS. The author puts forward a data model which stores map with big long binary field type in DBMS and seperats floor&house map with building map as well as its attributes. In addition, Hangzhou DRES has been illustrated as an application of GIS.
