A method and system for plotting an area on a map of a mobile terminal

Abstract

The invention discloses a method and a system for drawing an area on a map of a mobile end, which relates to the technical field of drawing. The method comprises the following steps: waiting for obtaining a click signal of a touch main body on the map of the mobile end, judging a click position; if the click position is a target area, obtaining a coordinate point of a corresponding target area, and taking the coordinate point as a corner point; If the clicking position is non-target area, then continuing to wait for the clicking signal; according to the coordinate point position correspondingto the corner point, marking the mark point corresponding to the corner point on the moving end map and storing the mark point into the mark point set; continuing to wait for obtaining the click signal and the corner point corresponding to the click signal, judging whether the corner point addition completion signal is received or not, if not, continuing to wait for obtaining the corner point andadd the mark point corresponding to the corner point to the mark point set, if received, according to the mark point in the mark point set, performing drawing to form a closed area. Thus, the user candraw an area on the map of the mobile terminal independently.

Description

technical field [0001] The present application relates to the technical field of drawing, and in particular, relates to a method and system for drawing an area on a mobile terminal map. Background technique [0002] With the development of science and technology and the improvement of people's living standards, mobile phones have become an indispensable part of life. Slowly, Baidu Maps, Gaode Maps and other applications with maps as the core technology have also emerged. These map manufacturers not only It provides self-developed map applications for the general public to use, and also provides SDKs (Software Development Kits) corresponding to each platform for application developers to use, which is convenient for developers to quickly integrate map functions in their own applications. There are many such map manufacturers, and the methods of using the SDK provided by them are basically the same. Let's take Baidu Maps Mobile SDK as an example to illustrate. [0003] In ord...

Problems solved by technology

Because the analysis process relies on the server to complete, the search conditions must be uploaded. This process requires an Internet connection. If our production environment is a specific network that cannot be connected to the Internet (such as a public security network or a company LAN), it cannot be completed.

[0006] (2) The search result is uncertain, because the search result depends on the search conditions and search algorithm. If the user makes an error or the back-end search algorithm is defective, the search result may not be what the user needs or there is no return result at all. At this time, the user needs to search again. Refine keywords for search

[0007] (3) Unable to customize the area, the user can only choose to use the returned result and re-search. The returned result is an artificially provided area range. In theory, it is a standard POI area, but in our actual use, it may be that we need non-standard POIs. Point area, for example, the user only wants to select the central area of ​​the parking lot. After entering the keyword of the parking lot, the area range of the entire parking lot is obtained, so that the specified area is expanded

[0008] (4) There are many user operations

The fundamental reason is that most applications provide fuzzy search, displaying as much information as possible to users, allowing users to have more choices, and when users need to accurately specify a certain area, especially a custom area, These methods are not applicable, which requires us to develop a method that allows users to draw areas on the map
