| As a new way of gravimetry, airborne gravimetry plays a great significant role in earth science, geological exploration and national security. It has wide application prospect and development space. The research and development of gravimetry data post-processing software is beneficial to the data processing and application of airborne gravimetry. According to the procedure of airborne gravimetry, gravimetry data post-processing software is learned and developed. Main contributions and innovations are as follows:The procedure, theories and realization of airborne gravimetry data processing is researched first. Focuses are pretreatments, principle of the gravity anomaly and filtering.A gravimetry data post-processing software on Oasis montaj is realized based on plug-in architecture and three-tier architecture. Each plug-in component of gravimetry data post-processing is implemented both user interface and function. Related components are pretreatments, pre-correction and post-correction, line selection, anomaly calculation and filtering, wave display, and log. Each plug-in component works well under montaj. The method and procedure is without difference for different data, the operation history is also recorded.A plug-in gravimetry data post-processing software based on reflection under.NET is also developed. The mainly technology is XML and ADO.NET and so on. The system is furnished with project management, menu management, data management and visualization management. It is available for plug and play, and has a good extensibility and customization. With each component of gravimetry data post-processing plugged in, the whole system runs correctly and stably. The plug-in system can improve the development efficiency meanwhile reduce the cost.Gravimetry data post-processing softwares implemented in this paper all have friendly user interface, integrative work flow, and engineering management. It will contribute to the application and promotion of airborne gravimetry. |
