[0061] (1) Prepare tile map data

[0062] ① Slice the map data, and the storage path format is C:\vec\L1\R2\C3.png;

[0063]②Save the tile data folder to the C:\vec path of the server hard disk;

[0064] (2) Define the path (URL) format of the requested tile

[0065] path: http: / / 10.120.20.244:7001 / vec / rest / 1 / 2 / 3

[0066] (3) Tile resource request, request tiles according to the path format in step (2), and send 100 requests at the same time

[0067] (4) After each request is received, the following same operations will be performed respectively

[0068] ① Determine whether the basic thread in the thread pool is full. If not, a new thread will be created immediately to execute the tile request task. If it is full, it will enter the next process.

[0069] ② Determine whether the tile request task queue in the thread pool is full. If not, store the newly submitted tile request task in the tile request task queue. If it is full, enter the next process.

Abstract

The invention relates to a map tile data publishing method. The map tile data publishing method comprises the steps that (1) tile map data are prepared; (2) the path format for requesting a tile is defined; (3) the tile is requested according to the path format; (4) a request receiver receives a request, and new tasks are added; (5) a resource schedule has access to a resource pool; (6) a cache management algorithm is used, and the resource pool is managed in a Hash chained list storage mode; (7) tile resources are output. Programs compiled according to the method are lightweight directory services, an installation file is small, the access path is simple and clear, large concurrent processing is supported through management on a thread pool, and the response speed and the response effect are increased remarkably.

Description

technical field [0001] The invention belongs to the technical field of geographic information processing, in particular to a method for releasing map tile data. Background technique [0002] With the rapid development of the Internet era, geographic information systems have also greatly improved the quality of people's daily life, such as the navigation of vehicles, the location search of hotels, etc., all of which are inseparable from the visualization of maps. tile service. The tile is to cut the map into small pictures of the same size through certain rules. When the user accesses the map, each small tile picture will be requested and stitched into a map picture of the current range through the client program, because the request on the Internet The amount of concurrency is very large, and the response efficiency of the tile service becomes the key to a good user experience. This invention is to improve the response efficiency of the tile service and apply a resource-ori...
