Tile data acquisition method and device, equipment and storage medium

Abstract

The invention discloses a tile data obtaining method, device and equipment and a storage medium, the method and device are applied to a cache server, the cache server comprises a first-level cache and a second-level cache, and the method comprises the steps that a spatial data access request sent by a client is received; under the condition that the target tile data is not cached in the second-level cache and the target tile data is cached in the first-level cache, sending the target tile data to the client according to the fact that the business data does not exist in the geographic space range to which the target tile data belongs; and when the business data exists in the geographic space range to which the target tile data belongs, rendering the business data on the basis of the target tile data, and sending the rendered tile data to the client. According to the method, by constructing a new cross-category spatial data rapid rendering and caching method, spatial data can be rapidly rendered and displayed across various clients, the user experience of geographic spatial information comprehensive service is improved, and the user experience is greatly improved through timely data feedback.

Description

technical field [0001] The present application relates to the technical field of spatial information, and in particular, to a method, apparatus, device and storage medium for acquiring tile data. Background technique [0002] Geospatial data is a mapping of spatial objects of the real geographic world in a virtual digital world, a conceptual digital abstraction of real-world geographic entities. Geospatial data can be divided into two categories: basic framework spatial data and business application spatial data. Basic framework spatial data is used to express the basic components of the real world, such as urban components, place name data, etc., mainly from the national basic surveying and mapping data products, such data rarely change, or change slowly in units of years; business applications Spatial-like data changes at any time according to the needs of application scenarios. Sometimes we need to organize these two types of data for unified modeling and unified managem...

Problems solved by technology

[0006] Related technologies use layer as the basic unit of spatial data rendering and display, which lacks the organic correlation between static basic spatial data and dynamic business spatial data, and is difficult to meet the needs of integrated processing of cross-level and cross-category spatial data. display requirements

Moreover, the existing tile mechanism to improve data access performance is mainly used for caching spatial data of basic frameworks that rarely change, and cannot effectively handle cross-level, dynamically changing spatial data, and insufficient timely data feedback has a great impact user experience

[0007] For the above problems, no effective solution has been proposed
