Description

technical field [0001] The invention relates to a three-dimensional geological modeling and related technologies, in particular to a multi-dimensional spatial information quality detection and analysis model and a modeling method. Background technique [0002] Since the 1970s, the research on 3D geological modeling and related technologies has become a hot spot, and many research results have been achieved. , affects the accuracy of the 3D geological model, and its reliability is directly related to the analysis and application effect of spatial data. Some scholars have emphasized that the conclusions of spatial analysis that cannot be based on accurate data are incorrect, and spatial information systems that do not consider quality can produce various garbage at a relatively fast speed. Therefore, the detection and evaluation of spatial information quality in 3D geological modeling has become one of the most challenging topics in the world. [0003] In the prior art, some...
