Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem of unsatisfactory map display results caused by the existing zooming method according to a fixed scale, the present invention provides a method for zooming a map based on resource distribution, which includes the following steps : Obtain the first zoom ratio of the map; obtain the resource distribution information of each sub-region of the map; calculate the second zoom ratio of each sub-region respectively based on the resource distribution information and the first zoom ratio; make each sub-region of the map The region is scaled according to the second scaling factor of the subregion

Embodiment Construction

[0063] The map scaling method based on resource distribution provided by the present invention no longer simply scales the map with a fixed scale, but divides the map into multiple areas and calculates the map scale of each area based on resource distribution. In this way, after the user zooms the map, the zoom ratio of different areas on the map is adjusted with different map scales according to the basic scale (ie fixed scale) and resource distribution information (such as density), thereby optimizing In order to display the resource display on the device. It should be pointed out that the "resource distribution" in this article can be understood as distribution in a certain area on the map, such as restaurants, shopping malls, public facilities (such as ATM, gas stations, charging stations / piles), etc., or other mobile resources. resources (such as shared bicycles, mobile charging vehicles, etc.), as long as the distribution of a certain type of resources can be reflected o...

Abstract

The present invention belongs to the technical field of map zooming, and particularly relates to a resource distribution-based map zooming method and system, a memory, and a control apparatus. The present invention solves an issue in which an unsatisfactory map display result is caused by a current fixed-scale zooming method. A map zooming method provided by the present invention comprises the following steps: obtaining a first scaling ratio of a map; obtaining resource distribution information of each sub-region of the map; calculating a second scaling ratio of each sub-region on the basis of the resource distribution information and the first scaling ratio; performing zooming on each sub-region of the map according to the second scaling ratio of the sub-region. The technical solution of the present invention allows more resource distribution information to be displayed on the screen of a display device, thereby optimizing the resources displayed by the display device.

Description

technical field [0001] The invention belongs to the technical field of map zooming, and in particular relates to a resource distribution-based map zooming method and system, a memory and a control device. Background technique [0002] Real-time monitoring of map-based resource distribution information is essential in the operation and maintenance system. Users can view the details of resource distribution in different regions on the map by dragging and zooming. The traditional map scale is fixed, that is to say, every time the user zooms in and out, each area on the map will be scaled accordingly according to the same scale. However, this scaling method has the following disadvantages: [0003] The response of all areas and resources (such as shopping malls, restaurants, public facilities, etc.) to the scaling operation is a similar passive adjustment process, that is, when the map is scaled according to a fixed scale, resources may be moved in or out after the scaling ope...
