The Design And Implementation Of Geological Survey Mapping System For Shandong Seismological Bureau Based On Android

The results obtained from geological survey work have been widely applied in various fields,such as minerals,earthquakes,and environmental geology,providing sufficient evidences for research in these areas.Shandong Seismological Bureau has paid great attention to the collected geological survey data to ensure its accuracy and completeness in many business decisions.In the current investigation and mapping work of the unit,the data obtained from the site survey cannot be mapped and processed in a timely manner,and the processing cycle is long.In addition,some errors and omissions may occur in the data reporting process,resulting in effecting the accuracy rate.Therefore,the Bureau decided to adopt the Android platform for the development of a geological survey mapping system.The system development process mainly adopt the Android platform technology.The platform is based on the Linux kernel,with application programs and system runtime as the main components.The application framework includes rich view components that can gain the front page with high interaction.Resource explorer and activity explorer can manage and process tasks such as data access and lifecycle.In addition,the Android platform has a comprehensive security mechanism with variety identification ways and fully application of the authority mechanism.The platform has been widely used due to its open source and practical features.SQLite is a kind of lightweight relational database,which is mainly used in the data management work of the Android platform system.The system includes wild route data collection service and other components.Wild route data collection service includes hand map function,route data processing and other links.Hand map function includes map opening,resetting,parameter browsing,and saving.The field route data includes geological points,subsection routes,photos,sketches,and samples,and the processing methods include collection,copying,editing,and deletion,realizing the processing of the route data.Measuredprofile data collection includes two data collection services,with base map and without base map,and can manage the basic information of the profile measurement library and the profile.The application of the system has significantly improved the accuracy and convenience of the geological survey mapping work of the Shandong Seismological Bureau.Employees can use the system to directly report all types of data they surveyed on the site.Some tedious process steps have been streamlined and processing efficiency has been further improved.In addition,the use of the system ensures the comprehensiveness and the accuracy of the acquired data,which can provide full references for the daily decisions of the Seismological Bureau and improve the pertinence of the work.
