Development And Application Of Some Modules In Digital Hydrogeological Survey System

In order to push forward the new generation of information technology and intelligent equipment,deep integration has been carried out in hydrogeology survey,data collection,data analysis and processing,data exchange and transmission,The development and application of some modules of the digital hydrogeological investigation system have realized the digitalization,integration and refinement of hydrogeological investigation,It has enhanced the support and timely service ability of the geological information service to the economic and social development.The digital hydrogeological survey system includes field data acquisition system and desktop processing analysis system,They are used in hydrogeological investigation,field work stage and indoor finishing stage respectively,and different operations are performed on the hydrogeological survey database.The digital hydrogeological investigation system adopts plug-in development mode,This plug and play method enhances the running and maintainability of the program,A module is a plug-in,It is easy to develop and manage.The development includes database module,data drawing and editing module and pumping test module.The database module has provided the prerequisite and the condition for the rapid acquisition,processing and service of the hydrogeological survey data according to the database built by the hydrogeological survey standard,and is the basis of the hydrogeological investigation information.Data mapping and editing module developed light GIS system based on DotSpatial open source class library,Rendering 1:5 million standard frame,display and man-machine interactive editing function of field geological survey line.The pumping test module realizes the automatic fitting and parameter analysis of the time drawdown curve of pumping test based on Android,It avoids the time-consuming,laborious and low efficiency of pumping test.Using Mono,for,Android development,to solve the cross platform and programming language restrictions.The development module has been tested by digital hydrogeological survey system,The desktop system realizes the efficient management of hydrogeological survey data,with fast mapping speed and high operability.The mobile pumping test module provides a new way for field pumping test because of its convenient carrying,easy management,and accuratefitting and seeking parameters,The utility model has certain guiding function,and verifies the practicability and validity of the Digital Hydrogeological Investigation System.
