Research on earthquake emergency response technology based on Google Maps data

As is well known, earthquake often inflicts severe casualties and property losses. The occurrence of earthquakes cannot be reliably predicted by current technology, therefore the earthquake emergency and rescue is an important part of protecting against and mitigating earthquake disasters. Basic geographical data play an important role in earthquake emergency work. However, it is hard to acquire the spatial data of the earthquake site in short time. Therefore, the Google Maps data could be applied in the early stage of post-earthquake emergency work. This paper discusses the principles of Google Maps and technologies of applying Google Maps data in earthquake emergency work. The downloading and merging algorithm is designed and implemented. Using Google Maps data and the program, we produced thematic maps in real earthquake emergency work. It is proved that the methods are feasible and have great practical application significance.
