Gravity Data Preprocessing System Is Developed

Gravity data processing contains collecting gravity data and computing all correction of gravity anomaly. It is well known, gravity data processing is an extremely complex work. Each stage of every processing involves much computation work. On those years before 80's of last century, these work is mostly completed artificially. The efficiency is lower and easier to make mistakes. Take correction for topography as an example, it is necessary to get much data on the topographic diagram, although we can manufacture terrain quantity board to conveniently compute, it cannot fundamentally solve the problem of altitude work. With the development of computer application technology, On 80's of last century, some geophysists started using computer to process the gravity data. The processing methods are various, but as now it has not formed complete software. It is not advantageous for the gravity data processing in time when the field exploration carries on.For solving these questions, author collected and reorganized many kinds of experiment computational method of the gravity apparatus as well as the gravity data reorganization and the gravity anomaly correction computational method, And has researched these computational methods, Developed a software applied mechanically in the gravity data processing under the Fortran language environment. As the result, it is convenience for prompt carry on the gravity data processing in fieldwork; also it is advantageous for inspection the accuracy of observed gravity data. Through calculating the observational data made satisfactory results.
