摘　　要：传统的数据分析平台多基于数据充足的理想情况进行研发,往往与数据不完整的现实相去甚远,难以满足实际应用的客观要求,因此,有效处理数据缺失就成为信息化工作的关键。本文针对“河北地面沉降系统”研发应用中的数据缺失问题,将已经发展成熟的插值技术,应用到地面沉降等值面的构建中,对信息化管控防治工作中的实际难题进行探究和解答。数据曲线插值的关键在选取合适的插值方法,本文基于简洁宜行的原则,提出Akima插值和GP服务相结合的地面沉降等值面的建模方法。该方法由2个部分组成,一是用Akima插值有效解决水准点观测序列不连续问题;二是基于GP服务实现地面沉降等值面的自动化构建。在河北部署的系统运行结果表明,所提方法不但快速有效地补全了缺失数据,绘制出的等值面与实际生产情况相符,而且还基于微服务的编程思想,达到了系统耦合度低,方法易用灵活的目标。Traditional data analysis platforms are mostly developed based on ideal conditions with sufficient data,which are often far from the reality of incomplete data and are difficult to meet the objective requirements of practical applications.Therefore,effective processing of data missing becomes the key to informatization work.Aiming at the problem of missing data in the development and application of the“Hebei Land Subsidence System”,this paper applies the mature interpolation technology to the construction of the equivalent surface of land subsidence,which is an exploration and answer to the actual problems in the information management and control work.The key to data curve interpolation is to select a suitable interpolation method.Based on the principle of simplicity and practicability,this paper proposes a method for modeling the land subsidence isosurface combining Akima interpolation and GP service.This method is composed of two parts.One is that Akima interpolation is used to effectively solve the problem of discontinuity of the benchmark observation sequence.The second is to relize the automatic construction of the ground subsidence isosurface based on GP service.The system deployed in Hebei and the results of its operation show that the proposed method not only fills in the missing data quickly and effectively,and the isosurface drawn is consistent with the actual production situation,but also achieves the goal of low coupling and easy to use and flexible method based on the micro-service programming idea.
