Design And Implementation Of Geophysical GIS Data Collection Based On Android

With the development of communication technology and the using of smart phones,the pace of intelligence for geophysical survey has been accelerated.In order to improve the efficiency of field geophysical survey,it is urgent to improve the collection method of field GIS data.For field data acquisition,GIS system has been widely used in all walks of life.The research shows that using GNSS data module and Bluetooth module of smart phone and database for data acquisition can standardize data and improve production efficiency.Based on the background of geophysical survey,this paper analyzes the working process of geophysical field survey,and the main research contents are as follows:(1)The system has implemented coordinate acquisition and quality control of geophysical GIS data.GNSS data is received by GNSS module and Bluetooth module of Android device.After analyzing gpgga data,it is distributed to Stellite Activity.The data is sent to make satellite cloud image activity and quality control of geophysical GIS data,to provide accurate position data for users.(2)The system has implemented the design and implementation of database for data classification management.Clarifying the field surface data acquisition process,combined with the measured data,the system data is classified.Through the coordinate system files,point and project data files adn layer files,this three different databases can ensure the security of data collection management,and significantly improve the efficiency of geophysical point navigation and map vector data display.(3)The system has implemented the functions of map display,map drawing,geophysical GIS data attribute collection,including video,audio,text,vector collection and wireless data upload and download function.The system is widely used in the field projects,which improves the traditional field geophysical survey operation mode,improves the real-time and accuracy of geophysical GIS data acquisition,improves the production efficiency,and meets the needs of field geophysical survey for GIS data acquisition and mapping.
