Abstract In this paper, a model is constructed for evaluating the potential geological hazards in areas designated as the class C building classification on the slope land. The development of unstable slope land often concurs with dangerous geological hazards. Various mass movement hazards, such as landslide, slump, creep, and mudflow, may be triggered by indiscriminate development activities on slope land with high hazard potential. Government land management administration often lacks both adequate tools and data to assess the potential hazards which are likely to concur with the development of certain areas. It is critical for the land manager to integrate data from various sources within the government agencies, and to use the geographic information system as an able assistant to obtain speedy and proper evaluation results.
