This paper is a study on the development of a data analysis platform that constitutes a part of the development task of the constant monitoring system that can prepare against the earthquake disaster by using the regular measurement data of the old school buildings. The data analysis platform is composed of database management software that manages the metrology data acquired by using the instrument and data management software that analyzes the metrology data, analysis tools that can analyze the metrology data in various ways, A data analysis platform can be used to assess the safety of the school building and evaluate the seismic safety of the old school building to build a system for earthquake disaster.
