Study On Real Estate Location Based on GIS Technology

Abstract

Through a review of relevant literature,this study categorizes factors affecting real estate site selection into three main categories: environmental, social, and economic, termed as the "triple bottom line." Based on the "triple bottom line," a PUM (Portfolio Underwriting Model) model was constructed. Meanwhile, GIS technology was utilized to identify the locations of public transportation stations, medical institutions, schools, and fire stations within Xiamen City. Additionally, different regions were delineated into suitable residential areas based on slope, aspect, land type, and per capita GDP. Combining the PUM model with GIS technology ultimately aids in real estate market site selection. The research findings indicate that integrating the PUM model and GIS technology for real estate site selection allows for a more scientific and comprehensive evaluation of various site selection factors, thereby providing important decision-making support for developers and investors.
