2D map data dynamic analysis caching method

Abstract

The invention provides a 2D map data dynamic analysis caching method. The method comprises the following steps: uploading floor map data, collecting general route shops of a database to be establishedas comprehensively as possible; carrying out public facility, the line calculation between the elevators in a background information base; sending the data to a background service in a POST mode; therefore, the capability of optimally selecting the sub-mall and sub-floor routes of the floor navigation data is improved. According to the invention, the index is created to find the general route store in the path finding process; the public facility, the line calculation between the elevators is carried out at the background; the enhancement of processing capability is enabled, the circuit is optimized; the route calculation speed is further increased. Meanwhile, indexes are established for the data, the client side can conveniently and quickly search for relevant information of the corresponding route, the data is encrypted and stored with floors as units. Meanwhile, the data is merged into the shopping mall global data and output as a static JSON file, CDN acceleration is conducted onstatic resources, and the client side can conveniently obtain the static resources.

Description

technical field [0001] The invention belongs to the technical field of data analysis, and in particular relates to a method for dynamically parsing and caching 2D map data. Background technique [0002] Map cache is a dynamic parsing and caching optimization strategy for 2D map data. Map cache actually contains a series of map tile files with a certain scale. Zooming out and panning will send a URL request to the server. At this time, the server will return the pre-generated map tiles according to the request, so as to reduce the burden on the server and quickly display the map, improving the map browsing speed. [0003] The dynamic map service means that when the client sends a request to the server to view the map service, the server will generate a picture according to the requested range, and then return the picture to the client. If another client requests to view a map of another range, the server will generate another image and return it to the client. Since these p...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of 2D map data dynamic parsing cache method, aims to solve the traditional 2D map data dynamic parsing cache of the route in the middle of the prior art to find the nearest general route (store, public facility, elevator) to reach the target floor When the calculation of the nearest point overlaps strongly, it is impossible to quickly delete redundant points and delete dense adjacent points to reduce the time-consuming wayfinding. After reaching the target floor and changing the route, there is a broken line in the middle, and navigation will not be possible. , the calculation task is completely placed on the client side using js calculation, there are certain problems in performance
