Abstract

The invention provides a map labeling method and system. The map labeling method comprises the following steps: a distributed calculating system obtains original map data; a task scheduling server performs grid segmentation on the original map data to obtain multiple grid map data and distribute the grid map data to multiple task executing servers; the task executing servers performs avoiding calculation on the grid map data and labels each element in the grid map data; the task executing servers distribute elements and corresponding labeling results to multiple task executing servers according to multiple labeling results sent by the task executing servers and ID of the elements; the task executing servers merge and de-weight the labeling results of the elements to obtain labeling results of the elements in an original map. By adopting the map labeling method and system, the data volume handling capacity and handling speed are greatly improved.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a map marking method and system. Background technique [0002] At present, when labeling a map, a server is usually used to process map data and label elements in the map. The problem is that due to the limitation of server resources, when a single server processes massive map data, the data volume is large, the processing process is complicated, the calculation time is long, and the processing speed is very slow. Contents of the invention [0003] The present invention aims to solve at least one of the above-mentioned technical problems. [0004] Therefore, the first object of the present invention is to propose a method for labeling maps, which can greatly improve the throughput and processing speed of data volume. [0005] The second object of the present invention is to propose a map labeling system. [0006] In order to achieve the above object, the map l...
