Abstract: 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.
