| Abstract: | Based on the analysis of the shortest path algorithm,this paper offers the shortest path inquiry functions between two geospatial points in the geographic information system-based prediction and deci-sion-making system for the seismic hazard.The effective application of the results in this paper willl pro-vide reference for the emergency rescue after the earthquake. |
