Abstract

The embodiment of the invention discloses a frame data processing method and device of an electronic map, which are applied in the technical field of information processing. In the method of this embodiment, the frame data processing device of the electronic map will determine the second-level attributes of the objects in each frame in the multiple frames of the first-level electronic map, if the second-level attributes of the objects in the first frame If the first-level attribute is a plurality of second-level attributes, the object of the first frame is divided into objects of multiple sub-frames according to the second-level attribute, and then the object data of these multiple sub-frames are stored in the corresponding second-level data package , or directly store the object data of the first frame in multiple second-level data packets. Since there is no need to segment the objects of each frame of the first-level electronic map, or not to perform any segmentation on the objects of each frame, the obtained second-level data package data will not increase exponentially. When stored in After the server, it will not affect the computing efficiency of the server.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method and device for processing frame data of an electronic map. Background technique [0002] Existing electronic map (referred to as map) application terminals (such as Tencent Maps, etc.) can realize the offline map function. This offline map function requires the map application terminal to download the offline map data package from the server in advance, so that the map application terminal uses the offline map data. No network traffic will be generated while the packet is in progress. [0003] The existing offline map data package is usually based on the province, and each province corresponds to an offline map data package. Each offline map data package contains the object data of several map frames of the provincial electronic map. Each map frame has It is the only one, and the coverage of the map is about 100 square kilometers, which is a relatively la...
