Abstract

The invention is applicable to the technical field of surveying and mapping geographic information, and provides a quality control method and device for geographic national condition monitoring data and terminal equipment, and the method comprises the steps: obtaining an uncertain event of the geographic national condition monitoring data in a production process and a logic relation between uncertain events; Constructing a Bayesian network-based geographic national condition monitoring data production process error propagation model; Performing fuzzification processing on the error rate of each basic event in the geographic national condition monitoring data production process error propagation model to obtain a fuzzy probability; Based on the fuzzy probability and the conditional probability between the uncertain events, calculating an error rate of the geographic national condition monitoring data; Based on the fuzzy probability and the error rate, calculating fuzzy importance and posterior probability of each basic event; And feeding back the fuzzy importance and the posterior probability of the basic event to the user. The technical problem that a quantitative quality control method is lacked in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of surveying and mapping geographic information, and in particular relates to a quality control method, device and terminal equipment for geographic national condition monitoring data. Background technique [0002] The quality control of geographic national conditions monitoring data is the premise of obtaining reliable land surface change information, which has a significant impact on application decision-making. The current quality control of geographic national conditions monitoring data is mainly based on data quality standards to evaluate the quality of the results, limited by high-quality ground reference data, and less involved in error propagation and quality control issues in the process. [0003] Quality evaluation methods include direct evaluation methods and indirect evaluation methods. Among them, the direct evaluation method is to sample the data set, calculate the data quality score according...
