Abstract

The embodiment of the invention provides a region division method and device, and the method comprises the steps: receiving a region division request which at least comprises original region data, a starting point element class and a search level; combining a preset area line element class and a road line element class in the original area data to generate target area data; and starting from the starting point element class in the target area data, performing topological search on the line element class of which the weight level is lower than the search level to obtain a target surface elementclass. According to the embodiment of the invention, the line element class of the preset area is combined with the road line element class to obtain the target area data; and topology search is carried out to carry out automatic region division, so that the defects of road section missing, suspension points, unclosed polygonal regions and the like of original region data are eliminated, the applicable range of region division is expanded, and the accuracy of region division is improved.

Description

technical field [0001] The invention belongs to the field of computer application technology, and in particular relates to an area division method and device. Background technique [0002] The division of urban areas is based on the way of land use. The land use methods and functions of various urban areas are different. Each part is teamed and unified with other parts to form an organism together. [0003] In recent years, due to the rise of intelligent transportation, many urban area division methods are based on traffic big data, and the obtained characteristic areas have a strong correlation with traffic travel, which weakens various urban planning data, such as rivers, roads, pipelines, etc. The natural enclosure of characteristic areas is more suitable for traffic planning, but cannot meet the individual needs of urban planners, and has poor applicability. Moreover, city managers do not make sufficient use of urban planning data. There are problems such as missing roa...
