【摘要】 随着地球物理学的不断发展,磁法探测也得到广泛的应用,一套集成数据输入,处理以及成图的软件越来越急需。现有的能用来处理磁测数据的软件也多是输入,处理,成图各自独立的软件,并且是针对不同的磁力仪设计不同的软件。本软件使用Compaq Visual Fortran 6.5编写,针对各种常用的磁法仪器,包括CZM-3型质子磁力仪,PMG-1型质子磁力仪,GSM-19T型质子磁力仪,MP-4型质子磁力仪,G856型质子磁力仪,WCZ-1型质子磁力仪,收集数据格式,设计数据转换模块将其转换成统一的磁力仪数据格式,包括日变站观测数据格式和普通观测点数据格式两种,在系统中使用;对生成的数据进行数据预处理,在数据成图模块中产生MapGIS的明码格式文件,这些文件经过文件转换系统处理,然后组合起来即形成常用的磁测数据图件:实际材料图,磁异常剖面图和磁异常平面剖面图等图件,所有图件可以在MapGIS 6.5以上的版本中正常使用。软件还设计了可视化的界面,方便用户操作。本软件将使用户更方便地做磁测数据的输入,处理及成图工作,经过了实际数据的测试,可应用在实际的磁测数据处理工作中。更多还原

【Abstract】 Magnetic prospecting has been widely used as geophysics has been developing continuously, and a set of software which has combined modules of data inputting, data pretreating and data mapmaking is urgently needed. At present, the software of magnetic data is mostly the kind of software which has the unattached function - inputting, pretreating and mapmaking, the different software is designed according to different kind of magnetometer as well.The software is developed by means of Fortran programming. Many forms of datum from the familiar proton-magnetometers including CZM-3, PMG-1, GSM-19T, MP-4, G856, WCZ-1 are collected, which can be transformed into datum of uniform format in the data transform module. Then, the data files after pretreated in the pretreatment module can be used in the module of data mapmaking, producing corresponding MapGIS code files which will be transformed further into MapGIS format files in MapGIS file transform subsystem, and the latter constitute universal magnetic data maps: Primitive data map, Magnetic anomaly plan-profile map, Magnetic anomaly profile map, and these can be wholly displayed in the software MapGIS the edition of that is above 6.5. The software concerned in this dissertation is also a set of visual-interfaced software that conveniences the users.The software will simplify the operations of magnetic data inputting, pretreating and mapping, which has been tested by the use of actual datum and can be applied in magnetic data processing in practice.更多还原
