Problems solved by technology

However, this display method requires the user to click on the target to display the detailed information, which increases the user's operation steps, and the display method is not intuitive enough, and it has a better display effect only on the premise that there is no need to intuitively display the detailed information of the data at one time
When it is necessary to display a large amount of information based on geographic location on the map tool at one time, including image information, the existing technical solutions cannot be applied

Embodiment 1

[0039]Crawl the target name and corresponding address information and picture information from the network according to the field settings. For example, the name is Chengdu ABCD Technology Co., Ltd., and the address is: No. xx, the middle section of Tianfu Avenue, Chengdu. According to the address information, call the first map platform interface to obtain The geographic latitude and longitude information corresponding to the target address is: {"status": 0, "result": {"location": {"lng": 105.07392899855, "1at": 36.555138880016}, "precise": 1, "confidence": 80, "level": "\u5546\u52al\u5927\u53a6"}} From the returned information, it can be obtained that the reliability is: 80, the longitude is 105.07392899855, and the latitude is 36.555138880016.

[0040] The geographic latitude and longitude information corresponding to the target address obtained by calling the second map platform interface is: {"status": "1", "info": "OK", "infocode": "1000", "count": "1", "geocodes": [{"fo...

Embodiment 2

[0045] Obtain the names, addresses, longitudes, latitudes, and pictures of multiple targets in the same manner as in the embodiment; and import them into the corresponding index, and read the information of multiple targets through asynchronous loading when displaying geographic information , display the relevant information of the target at the corresponding position, such as image 3 shown.

Abstract

The invention relates to the field of Internet information processing, in particular to a map information display method based on asynchronous loading. When the user enters the target map information display page, the default map information is displayed first, and then the target's geographic coordinate information, text information and picture information are read through the thread; and the target is drawn on the displayed basic map page according to the target's coordinate position. Location and text and picture information corresponding to the target. It solves the problems of high memory occupation, low page refresh efficiency and screen freeze during synchronous display; ensures the smoothness of screen switching and improves user experience; the method of the present invention is applicable to the related service business of mobile intelligent terminals based on geographic information. High application value, especially suitable for situations where multiple targets need to be displayed on the map page at the same time and the text and picture descriptions of the targets need to be displayed.

Description

technical field [0001] The invention relates to the field of Internet information processing, in particular to a method for displaying map information based on asynchronous loading. Background technique [0002] The rise of mobile smart devices has provided many conveniences for people's life and work, among which smart phones are the most popular and widely used among mobile smart terminals. Various applications for smartphones are also constantly being updated and developed; existing smartphones have limited memory and load too many applications, and the screen often freezes when using them, especially when there are many pictures displayed at the same time At this time, because the image occupies a large amount of memory, it is generally read from the background and displayed on the front end; if the image is read from the background, it generally needs to be converted to a binary stream, and the reading speed will affect the screen. The effect of display and drawing, th...
