Problems solved by technology

For the spatial division of vector data, the Voronoi diagram can divide business districts with a single influencing factor. However, this method limits the consideration of multiple factors in the process of business district division, making the accuracy of business district division not high

Embodiment Construction

[0065] Below in conjunction with accompanying drawing, further describe the present invention through embodiment, but do not limit the scope of the present invention in any way.

[0066] The invention belongs to the technical field of commercial geographic analysis, and specifically relates to a method for dividing business circles based on cost-distance grids, and uses this method to express the influence of various commercial activity elements on the division of business circles, and applies it to the division and definition of Beijing business circles .

[0067] The specific operation steps of this method are as follows: figure 1 As shown, the following details are described:

[0068] A. Source data layer selection

[0069] The present invention selects 27 district-level business districts of Beijing to be divided as the source layer, as shown in Table 1:

Abstract

The invention discloses a commercial district division method based on cost distance grids. According to the method, spatial commercial activity elements are selected and constructed, cost grids are formed through symmetric difference processing, and cost values of grid units represent prices for crossing the units; and meanwhile, a continuous field model is used to express geographic spaces of the grids, distribution grids are obtained through analytical calculation of cost distances, and therefore commercial district division is realized. The method comprises the steps that multiple spatialcommercial activity elements are selected and constructed; the symmetric difference between the commercial activity elements is calculated, and regular grid data is obtained to serve as a cost layer needed for cost distance grid operation; a source layer of a to-be-divided commercial district is selected; each cost distance grid is calculated; and the commercial district is divided according to the distribution grids. Through the technical scheme, needed detailed data components within the commercial district can be provided during site selection and shop setup; and macro decision-making technical support such as commercial district development planning, layout and commercial development potential area analysis can also be provided.

Description

technical field [0001] The invention belongs to the technical field of commercial geographic analysis, and relates to grid data processing and business district division methods, in particular to a business district division method based on cost-distance grids. Background technique [0002] The rapid development of modern business economy and information technology has led to geometric growth of business data, which mainly shows the characteristics of massive, multi-source, heterogeneous, and high uncertainty. It is estimated that more than 80% of the information in commercial data is related to geographical location, which makes it possible to use geographic information technology for comprehensive analysis of spatial location and commercial business information. [0003] An important aspect of business geographic analysis technology is the analysis of business circles. The business district is the space with the largest radiation range formed by the center of the region a...
