Problems solved by technology

[0002] my country is a mountainous country, and the mountain area accounts for about two-thirds of the country's land area. Mountains play a pivotal role in natural resource management. At present, there is still a lack of clear boundary range and systematic research on mountain ranges, which can be obtained from public information The data is only a rough latitude and longitude range, and there is a lack of authoritative management agency management and mature standards to guide the demarcation of boundaries. Therefore, it is urgent to carry out research on the method of mountain range delineation

Embodiment

[0173] Taking Yanshan as an example, the implementation steps of mountain boundary delineation are as follows:

[0174] Step S1: Collect relevant information on mountain ranges; consult various documents and atlases, and make comprehensive analysis and judgment to obtain the following scope description:

[0175] Yanshan Mountain stretches across Beijing, Hebei, Liaoning, and Inner Mongolia, starting from the Yanghe River in Wanquan County and Huaian County of Zhangjiakou City in the west, reaching Shanhaiguan in the east, connecting Bashang Plateau, Qilaotu Mountain and Nuluerhu Mountain in the south, and Guangou Mountain in the southwest. Separated from the Taihang Mountains, the south side is the Hebei Plain.

[0176] Yanshan Mountain is an erosion and denudation mountain, the mountain body is east-west, with an altitude of 500-1500 meters, high in the northwest and low in the southeast. The eastern section is mostly low mountains and hills, generally below 1,000 meters abo...

Abstract

The invention provides a mountain range delimiting method and system, and belongs to the field of digital terrain analysis, and the method comprises the steps: collecting mountain related data; performing feature analysis on the mountain range related data, and determining an extraction rule; according to the extraction rule, extracting a mountain range contour line; aiming at the mountain range contour line, correcting the mountain range to obtain mountain range boundary line data; and carrying out map making integration on the mountain range boundary line data to obtain mountain range map making range data. The system comprises a data acquisition module, a rule determination module, a contour line extraction module, a mountain range correction module and a mountain range integration module. According to the method, the mountain range and the range of the mountain range can be accurately delimited, and a feasible and effective method is provided for delimiting the range of the mountain range.

Description

technical field [0001] This application belongs to the field of digital terrain analysis, and specifically relates to a method and system for demarcating mountain ranges. Background technique [0002] my country is a mountainous country, and the area of ​​mountainous areas accounts for about two-thirds of the country's land area. Mountains play a pivotal role in natural resource management. At present, there is still a lack of clear boundaries and systematic research on mountain ranges, which can be obtained from public information The data is only a rough latitude and longitude range, and there is a lack of authoritative management agency management and mature standards to guide the demarcation of boundaries. Therefore, it is urgent to carry out research on the method of mountain range delineation. Contents of the invention [0003] In view of the above technical problems, this application proposes a method and system for demarcating mountain ranges. [0004] In the first...
