Abstract: Combined with the requirements for seismic thematic mapping in earthquake emergency, this paper realizes the automatic acquisition of seismic information, the generation of seismic influence field and the automatic output of thematic map in QGIS and PostGIS by studying the open source GIS platform, and constructs a multi service parallel operation framework by combining with Docker micro service application container, so as to finally realize the automatic output of seismic thematic map based on the open source platform. The system improves the drawing efficiency and operation stability of seismic emergency thematic map, and reduces the cost of system development and operation and maintenance.
