Application of Open Source GIS Technology in Seismic Analysis and Forecasting System

In order to solve the copyright problem of MapInfo in earthquake industry, it is urgent to develop a seismic analysis and forecasting system based on open source GIS platform. In this passage, DotSpatial is used as the platform of open source GIS, the dynamic latitude and longitude labeling algorithm based on Least-squares method, the projection transformation algorithm and layer control algorithm are all used to optimize it. We applied multi-graph analysis and data superposition analysis of seismic monitoring data based on ASP.NET C # + MSChart technology, and use Com component technology to achieve a dynamic multi-chart based on the results of a single earthquake guide. Finally the software combined open source GIS with the field of seismic analysis and forecasting, which realized the componentized seismic analysis software based on open source GIS. The implementation of this project will provide strong technical support for the seismic analysis and forecasting.
