Abstract: Earthquake emergency thematic map provides timely and necessary technical support for earthquake emergency work. In order to shorten the mapping time of earthquake emergency thematic map, reduce the technical difficulty of seismic thematic map mapping, and improve the efficiency of earthquake emergency work, Hainan Province is selected as the research area to study and apply the off-line automatic mapping of earthquake emergency thematic map. In this study, the traditional idea of using GIS professional software for mapping process is advanced, and a series of pre-stored map slice data are established. When used, it will be separated from GIS software environment and emergency basic database. In software development, these pre-stored slice data are used to splice the needed emergency thematic map geographic base map, which has achieved the realization and application of rapid batch mapping to provide reliable and effective support for earthquake emergency work in Hainan Province.
