Geological map dynamic synthesis method and system considering proximity relationship

Abstract

The present invention belongs to the technical field of geological detection data processing, discloses a geological map dynamic synthesis method and system considering a proximity relationship, and proposes a dynamic geological map synthesis method for the situation of over-reliance on labor existing in the current geological map synthesis. The method can be used to comprehensively process the Jiaguan town map. By using the dynamic geological map synthesis method disclosed by the present invention, the process of over-reliance on manual participation in the traditional geological map synthesis process is overcome, and the method is more efficient; the weight of the geological body spatial information and attribute information is analyzed, and the experimental result is more accurate; clustering analysis and rough set calculation are used, and better effects are achieved; and the method can be promoted to other cartographic fields such as mineral resource maps, planning and utilizationmaps and other thematic maps.

Description

technical field [0001] The invention belongs to the technical field of geological detection data processing, and in particular relates to a method and system for dynamic synthesis of geological maps taking into account the proximity relationship. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] The development of economy and society needs strong geological data as support. In the era of big data, higher requirements are put forward for the ability of modern geological survey, management, processing and analysis. Geological data currently not only exist for the purpose of recording geological phenomena, but also It must meet higher requirements such as information resource mining and information services. At present, most of the small-scale geological maps used in my country are still hand-made by cartographers. With the continuous improvement of the application level of geological maps, the update t...

Problems solved by technology

[0008] (1) At present, the main problems faced by geological maps in terms of synthesis are: the diversity of geological data sources makes data processing difficult; the spatiotemporal attributes of geological data make the update process of geological maps slow; the value of geological data application sites

[0009] (2) The comprehensive process in the production of traditional geological maps relies heavily on manual mapping experience and level of mapping, resulting in long geological map production and update cycles, heavy update workload, and poor spatial information preservation accuracy.

The updating of thematic geological maps is slow
