For most marine surveying data processing tasks, such as gravity, magnetic or echo-sounding, to find and eliminate the errors among the raw data is a tedious and time-consuming process. Usually, the Graphical User Interface (GUI) software provided with the data acquisition system is very useful to reduce the manpower requirements and speed up processing. However, each tool typically only displays one specific data type or format. In this paper, a GUI program is designed for general marine geophysical data editing. It allows users to define their own data formats, and thereafter it can recognize the data type automatically according to the type of file extension.
