Abstract

The invention discloses an urban geological data cleaning method. The method comprises the following steps of S1, geological data preparation; a step; s2, establishing a standard stratum number; s3, establishing an attribute two-dimensional contour map; s4, screening and cleaning suspected points of the attribute two-dimensional contour map; s5, screening suspected points based on the three-dimensional geologic model; and S6, distinguishing and cleaning the suspected data by integrating objective data. According to the method, the structured warehousing data is cleaned and processed, the correctness and availability of the data can be judged, interference data can be removed, application end data can be optimized, two-dimensional and three-dimensional geological data display can be carried out, and modeling is accurate and reasonable.

Description

technical field [0001] The present invention relates to the technical field of urban geological data processing, and more specifically, to a method for cleaning urban geological data. Background technique [0002] As the carrier of geological work results, geological data has great potential and reuse value. With the improvement of informatization and intelligent application capabilities at the current stage, the informatization application of geological data is gradually increasing. The main application direction is reflected in the basic Construction of geological database, 3D geological modeling, secondary service of geological data, etc. [0003] During the development and construction of the city, a large amount of geological data is retained, which mainly includes engineering survey, regional geological survey, mineral geological drilling, geophysical and chemical prospecting and other information. According to the administrative management of different business direc...
