重力异常场云计算软件系统

摘要

Existing problems in the process of identifying gravity anomalies include cumbersomeness and complication of calculation,along with lack of uniformity in parameters and coordinate system.We develop a cross platform,cloud computing software system (OnGra) of the gravity anomaly field in order to resolve these issues.In accordance with the norms of the regional gravity survey and large scale scale gravity exploration specification,we design,reconstruct and integrate the existing gravity anomaly field processing algorithm with an adaptive extraction algorithm of regional digital terrain model.The software system can batch and automaticallycalculatethe air anomaly,the Bouguer gravity anomaly and the isostatic gravity anomaly from the field observation of gravity/GNSS.It can also calculate these anomalies based on satellite gravity field models in the specific region.%针对重力异常场计算中存在的处理流程繁琐、参数和坐标系统不统一等问题,开发一种跨平台的重力异常场云计算软件系统OnGra.该软件按照区域重力调查规范和大比例尺重力勘查规范,设计、重构、集成现有重力异常场处理算法和自适应提取计算区域数字地形模型算法,可依据野外重力/GNSS观测,批量、自动计算自由空气异常、布格重力异常和均衡重力异常,也可依据卫星重力场模型,提取和计算特定区域的重力异常场.
