Abstract

The invention discloses a method for extracting a mountain top point based on slope direction distribution characteristics. The method comprises the following steps: acquiring a slope direction value of a grid point corresponding to grid DEM data; forming corresponding target matrixes according to the slope values of the target grid points and the surrounding grid points in all directions, and obtaining potential mountain top point data according to the slope values of the elements in the target matrixes; and according to the potential mountaintop point data, rejecting a pseudo mountaintop point to obtain real mountaintop point data. The invention further discloses a system for extracting the mountain top points based on the slope direction distribution features and a storage medium. The method aims at obtaining the potential mountaintop point data according to the slope direction value, then the mountaintop point extraction efficiency is improved, and the real and reliable mountaintop point data in the grid area is obtained.

Description

technical field [0001] The invention relates to the technical field of digital terrain analysis, in particular to a method, system and storage medium for extracting mountain tops based on slope aspect distribution features. Background technique [0002] The top of the mountain is the key feature point that constitutes the skeleton of the terrain outline, and it is also the topographic feature point with the most obvious geometric characteristics within the mountain range. As a large mountainous country with mountainous areas accounting for more than 2 / 3 of the country's land area, China's in-depth research on the identification and extraction of mountain peaks in mountainous areas has important natural scientific significance for the study of natural landform distribution, biogeographic distribution, and natural environment changes. The raster digital elevation model is a basic data set used for feature analysis of various solid ground models, such as geomorphic feature anal...
