Abstract

The invention discloses a multi-format map tile generation method and system based on a distributed system, and the method comprises the steps: receiving a slicing task request, and carrying out the subtask division and distribution of a slicing task, wherein task parameters in the slicing task request comprise a preset tile format and a storage format; and performing distributed parallel processing on the slicing subtasks, generating corresponding map tiles according to the tile format, and storing the map tiles according to the storage format. By applying the scheme of the invention, the slicing task of the user can be self-adapted in various projections, various data formats, various output forms and the like, corresponding resources in the distributed system are reasonably called to quickly process data, and the method has extremely high benefits for improving the expansibility of the system and the economic benefit ratio of the system.

Description

【Technical field】 [0001] The invention relates to computer application technology, in particular to a method and system for generating multi-format map tiles. 【Background technique】 [0002] With the development of surveying and mapping technology, the volume of map data is getting larger and more frequent, and the present invention is mainly used to solve the problems of difficult dynamic update of map tiles and slow production speed. [0003] Map tiles are an optimization strategy to improve the user experience of map browsing. They are map tile files containing a series of scales and within a certain map range. The map tiles follow the pyramid structure, and each tile can be uniquely identified by level and row number. With the development of surveying and mapping technology, the volume of map data is getting larger and larger, and maps are updated more and more frequently. [0004] Under normal circumstances, it takes at least a few hours for an electronic map to gener...
