AI Technical Summary

Technical Problem

Existing technologies suffer from low real-time performance, low resource utilization, and difficulty in supporting high-frequency updates at the minute level in the rapid compilation and publication of geographic information base maps. In particular, the full tile compilation method consumes a lot of computational resources and has a high I/O load, while the incremental update method is prone to missed or false detections in change area detection, resulting in incomplete map data updates.

Method used

The range of tiles in the changed area is determined by the map data change time input by the user. A distributed engine is used to convert the tile range into tile coordinates and generate a list of tile keys. This is then split into parallel compilation tasks, distributed intermediate storage, and embedded database updates to avoid missed or false detections, thereby improving resource utilization and compilation speed.

Benefits of technology

It enables minute-level high-frequency updates of map data, reduces computational resource consumption and compilation time, improves compilation speed and resource utilization, reduces costs, and supports the parallel execution of large-scale distributed tasks.

Abstract

The invention discloses a method, a device and equipment for quickly compiling and publishing map data. The map data rapid compiling and publishing method comprises the steps of extracting a tile range of a change area according to map data change time input by a user; on the basis of a distributed engine, all the changed tiles in the tile range of the changed area are converted into tile coordinates, and a tile key list is generated according to the tile coordinates of all the changed tiles; splitting the tile key list into a plurality of parallel compiling tasks; for each compiling task, obtaining all element data of each changed tile in the compiling task from the map data set, performing tile generation, obtaining a tile file, and performing distributed intermediate storage; and acquiring tile files corresponding to all compiling tasks from the intermediate storage, inserting each tile file into an embedded database for storing map data according to tile coordinates corresponding to each tile file, generating a map data file, and publishing the map data file.
