Abstract

The invention relates to the technical field of urban geographic information processing, and discloses a road network density estimation method, a device, equipment and a storage medium. The method comprises the steps of collecting first road raster data according to the electronic map raster data; performing binarization processing on the first road raster data to obtain second road raster data;creating a road center line vector diagram layer, and extracting first road center line data according to the second road raster data and the road center line vector diagram layer; performing elementverification on the first road center line data to obtain second road center line data; and estimating the road network density according to the second road center line data. According to the road network density estimation method, apparatus and equipment, and the storage medium, the road center line vector data is extracted based on the electronic map raster data, so that quick estimation of theroad network density can be realized and the labor cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of geographic information processing, in particular to a road network density estimation method, device, equipment and storage medium. Background technique [0002] Road network density is of great significance for understanding the development status of urban transportation special planning and evaluating urban development. Road network density refers to the ratio of the total length of all roads in a certain area to the total area of ​​the area. At present, relevant policy documents and technical standards from the national, provincial and municipal levels have put forward specific requirements for road network density. It can be seen that this index is one of the important indicators of the economic rationality of urban road network planning and design, and it is also an important indicator of urban road analysis and research, special projects. Therefore, the rapid extraction of road network density is a...
