Based on the spatial geographic data display platform of Geographic Information System（GIS）, combined with the development process and need of archiving protection for traditional village in China, the basic structure of national traditional village cultural heritage data platform for the public is constructed. The traditional village cultural heritage data platform based on GIS includes four modules: front-end data collection, data platform display, protection planning system and background monitoring and maintenance. In addition to the general GIS spatial geography acquisition and analysis functions, the platform is connected with seven archival databases of village land planning, ecological environment, clothing and jewelry, production and living appliances, cultural activities, customs and literature, and establishes the mechanism of traditional village data visualization analysis and data early warning.
