Design And Implementation Of The Seaborne And Airborne Gravimeter Data Processing Software Based On Oasis Montaj

Seaborne and airborne gravimetry is an important way to get the earth gravity field.The development of seaborne and airborne gravity measurement technologies is base on the seaborne and airborne gravimeter and its ancillary gravity data processing software.According to the theory of gravimetry data processing,a data processing software based on the Oasis montaj is designed in this paper.Main contributions and innovations are as follows:The development tools of Oasis montaj are researched and the development environment is built.Focuses are the development of the database of Oasis montaj.After requirement analysis and system design,a seaborne gravimetry data processing software on Oasis montaj is developed by C#based on plug-in coding style and three-tier architecture.The software include a series of modules,such as pretreatments,correction time selection,line selection,gravitational anomaly calculation and filtering,wave display and accuracy analysis.The software works well on the Oasis montaj platform.An airborne gravimetry data processing software on Oasis montaj is developed by Oasis official programming language GXC.The software is designed as two parts:the basic module which focus on the data processing,and the extra module which focus on the result visualization.The basic module includes the vertical acceleration correction,Eotvos correction,latitude correction,free-air correction and FIR low-pass filter.The extra module includes coordinate transformation,line-drawing and meshing.The software also works well on the Oasis montaj platform and has a wonderful visual characteristic.The seaborne and airborne gravimetry data processing softwares implemented in this paper have friendly user interface,strong data management and easy-entensibility.The softwares will contribute to the application and promotion of seaborne and airborne gravimetry.
