Embodiment

[0033] figure 1 It is a flow chart of a vector tile data processing method provided by an embodiment of the present invention, the method can be executed by a vector tile data processing device provided by an embodiment of the present invention, and the device can adopt software and / or hardware accomplish. refer to figure 1 , the method may specifically include the following steps:

[0034] S101. Obtain a tile request parameter.

[0035] Usually, the front end sends a tile request to the processor, and the processor responds to the tile request to query tile data. In the actual application process, the geographic image of the area to be processed is first obtained, and then the geographic image of the area to be processed is sliced ​​to obtain the tile information of each tile at each level. These tile information constitute all tile data. Then query in all tile data. In a specific example, the area to be processed may be a relevant area in Haidian District, Beijing.

Abstract

The invention relates to a vector tile data processing method, a vector tile data processing device, vector tile data processing equipment and a storage medium. Calculating a space range of the request tile according to the tile request parameter; determining a target layer according to a layer display level filtering rule; calculating a target filtering rule according to the tile request parameter and the target distribution density of the target layer in the space range; and filtering the to-be-requested tile data according to a target filtering rule to determine target tile data, the front-end device generating a vector tile according to the target tile data. And the tile generation efficiency and the vector tile service performance are improved.

Description

technical field [0001] The present invention relates to the technical field of tile maps, in particular to a vector tile data processing method, device, equipment and storage medium. Background technique [0002] With the continuous development of the national economy and the continuous enrichment and improvement of national basic geographic information data, maps, as the carrier of data information visualization, play an increasingly important role in the decision-making of superiors. Map drawing is mainly based on raster tile technology and vector tile technology. [0003] However, the geographic element style of raster tile technology is not easy to update, and it is not easy to obtain high-resolution maps. In practice, vector tile technology is often used. Vector tile technology is a new technology for map data request and rendering. It transmits vector data in blocks in a certain format, renders and draws at the front end, making map generation more flexible and conven...
