一、航空物探的数据收录从1961年至1966年,国外少数航空物探测量公司开始在航空物探测量中采用了数据的数字收录。到1975年,西方在航空物探测量中使用数字收录方式的比例已占80％以上。在航空物探数据收录的初期,一般采用穿孔纸带方法,后来使用每时记录200或556个字符密度的磁带。到目前,都使用与计算机相兼容的磁带。应用数字记录的好处是十分明显的,它可以把空中记录直接送到通用数字计算机上,通过软件进行自动整理和绘图,代替了即花费时间又麻烦的手工计算和编绘图工作,并能提高资料处理、编绘图件的速度和质量。此外,使用场的各种数学变换程序,很容易为地质解释工作编绘出各种图件。
First, the data collection of aerogeophysical From 1961 to 1966, a few foreign airborne geophysical survey company began in the airborne geophysical survey data used in the digital inclusion. By 1975, the proportion of digital recordings used by the West in aero-geophysical surveys accounted for more than 80%. In the early days of airborne geophysical data collection, perforated paper tape was generally used, and later tapes were used which recorded 200 or 556 characters per hour. So far, computer-compatible tapes have been used. The benefits of using digital recording are obvious: it can send air records directly to a general purpose digital computer, auto-organize and map through software, replacing the manual and graphical work that takes time and hassle and improves data Processing, drawing pieces of the speed and quality. In addition, using the various mathematical transformations of the field, it is easy to draw a variety of maps for geological interpretation.
