Seismic Assist System Based On Android Platform

Handheld GPS is used for satellite positioning,geographic information collection,seismic line design,route selection,and waypoint and track navigation in the conventional seismic survey.With the development of seismic survey,the traditional handheld GPS has been unable to meet the requirement.According to the characteristics of seismic survey and management requirement,the seismic assist system has been designed and implemented based on the Android platform with the function of satellite positioning,data record,data queries,safety warning,and parameter setup and so on.The main research content of this paper includes:1.The integration of raster and vector data has been analysed based on the Android platform and mobile GIS.The first step is vector processing of raster image,then integration with vector data and checking data consistency to ensure consistent data.2.Various forms of database are setup according to the coordinates,water depth,well depth,migration and other complex attribute data from the field to use for different position.3.Characteristic elements of physical point,seismic line and attribute data(landlords,license,depth,etc.)are obtained with the Arc GIS secondary development,the Android platform and JAVA language,and implemented seismic assistant system.4.The warning signal was established when entering the danger zone which is already set up in the system according to the safety procedure to implement the advanced warning function.
