The invention discloses a basin and
peripheral area digital modeling method and
system based on
big data analysis, and relates to the technical field of digital modeling, and the method comprises the steps: connecting a GIS
system, and obtaining the
geographic distribution information of a target basin area; building a digital space, carrying out grid division on the digital space, and determining a digital grid; acquiring detection data of each exploration zone in the target basin area, performing
data interpretation and preprocessing respectively, and determining geological feature information; based on the digital grids, in combination with the geological feature information, performing three-
dimensional modeling on the digital grids in parallel, and respectively determining grid models; and splicing the grid models, determining a digital basin periphery model, performing macroscopic quantization, and generating a macroscopic digital basin periphery model. According to the method, the technical problem of low
model building efficiency in linkage modeling of the basin combined
peripheral mountain-building belt in the prior art is solved, and the technical effect of improving the efficiency and the accuracy of exploration and analysis of the basin and the
peripheral area is achieved.
