Abstract. The advancement of geoinformatics technologies promotes national-level attention to heritage inventories and digital platforms. The management of heritage sites requires a more efficient and flexible collection methodology to collect GIS data and support extended applications. This paper discusses the system design and application of Yingshao platform, a more flexible and efficient data collection platform for Chinese heritage sites and full lifecycle management. It applis a framework of WebGIS, MobileGIS and WebGL and adopts a data storage scheme of MySQL and MangoDB. Based on the advanced system architecture, the platform has formed better solutions: (1) establishing a standard and cooperative workflow; (2) integrating diverse data sources; (3) building a flexible geospatial database with a time dimension; (4) ensuring data security and safety. In the applications in China's heritage sites, it significantly improves the efficiency and flexibility during collection. Meanwhile, the collected data could well support management scenarios. We believe that the platform could become an effective and flexible data collection and management tool for China's heritage sites, and it has the potential to become the foundation for full lifecycle management.
