Method and device for realizing administrative region aggregation based on leaflet

Abstract

The invention discloses a method and device for realizing administrative region aggregation based on leaflet, and the method comprises the steps: loading a map from a rear-end server, and initializingthe map, so as to obtain all needed geographical administrative ranges in an administrative region, the map being leaflet; creating a plurality of polygon objects in all geographic administrative ranges; calculating the position of the mass center of each polygon object; acquiring all point location information in the administrative region from a back-end server, and performing traversal calculation processing to obtain a geographical administrative range to which each piece of point location information belongs; and then, locating the processed information of each point location to the masscenter position of the corresponding polygon object. The method has the advantages that the leaflet is used, the operation speed is high, complex distance calculation and repeated iterative processingare avoided, the situation of clustering icon overlapping or point location omission is avoided, and the method is suitable for most application scenes and wide in application range.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for realizing administrative region aggregation based on leaflet. Background technique [0002] At present, K-means clustering is a well-known algorithm for dividing clusters. Due to its simplicity and efficiency, it has become the most widely used of all clustering algorithms. Given a set of data points and the required number of clusters k, k is determined by the user, and the k-means algorithm repeatedly divides the data into k clusters according to a certain distance function. [0003] Each map API and plug-in basically has its own packaged and written clustering API or plug-in. At present, most of them use the respective APIs and plug-ins of these map manufacturers. But there are the following disadvantages: [0004] 1. Performance issues. In the case of a large amount of data, the algorithm needs multiple iterations to complete, which con...
