Abstract

The invention relates to a method and a device for optimizing building group displacement in a map. The method comprises the following steps: defining the clarity of map expression, the accuracy of geographic positions and the consistency of spatial distribution features as constraint conditions for building group optimization, defining the clarity of map expression and the accuracy of geographicpositions as a target function of building group optimization to obtain an optimization model of building group displacement; superposing the Thiessen polygon of each to-be-optimized building and a buffer area to solve an intersection, and generating a displacement safety area of each building; and on the premise of carrying out displacement limitation on the building according to the displacementsafety area, carrying out optimization solution on the optimization model by adopting an immune genetic algorithm to obtain a global optimal displacement operation scheme of the building group considering the spatial distribution characteristics. When the building group is subjected to shift optimization solution, the shift range of each building is limited by constructing the shift safety area of each building, so that the spatial distribution characteristics of the buildings are kept.

Description

technical field [0001] The invention relates to the technical field of map-drawing synthesis, in particular to a method, device and computer storage medium for optimizing the displacement of building groups in a map. Background technique [0002] In the process of cartographic synthesis, due to the reduction of the scale, the map space is also reduced, and some elements have to be exaggerated with symbols larger than the actual size, resulting in spatial conflicts between adjacent objects on the map. In order to maintain the clarity of the map, these conflicts must be handled by operations such as selection, merging, exaggeration, and shifting, among which shifting is the most commonly used operation to resolve such conflicts. Buildings are an important human element in general maps and thematic maps, and the resolution of neighborhood conflicts within building groups and between buildings and adjacent streets is a difficult problem in the process of map synthesis.
