Abstract
The exterior wall area of the house is an important part of the housing allocation area.Its accura-cy will directly affect the practicality in real estate surveying and mapping.In this paper,based on the in-dependent development of real estate mapping software platform,by using GIS spatial data topological op-erations,relative datas in real estate mapping have been condtucted,and a technology route which spacial data processing can be realized by only using vector data has been designed.It can avoid general and special problems in calculating exterior wall area,improve the work efficiency,save the operation time,and im-prove the accuracy of area measurement.It has achieved good results.关键词
