[0004] Although the SDK provided by the manufacturer can be conveniently used for development, it is necessary to accept the advertisement pop-up information imposed by different manufacturers on users using the SDK, the large service provider log icon, and the blockade of foreign map providers such as Google by GFW, and the actual application There will also be criticisms that the application occupies the wifi link and cannot load offline maps at the same time

Embodiment Construction
[0038] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0039] A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only for facilitating description of the present invention and has no specific meaning by itself. Therefore, "module" and "component" may be used mixedly.
[0040] The original data sources of map resources are mainly the map image resources formed by each satellite using high-power cameras to cut and take pictures of the earth and then splicing them together, such as figure 1 shown. This is different from the map service that is usually browsed with a browser, and it is not suitable for users to use. When users use the mouse to slide up, down, left, and right on t...

The invention discloses a map resource localization realization system and method. The method comprises the steps of locating a specified position of a user on a current application to a corresponding longitude and latitude position on a map; calculating a graphic block number of a region where a cursor of a mouse is located according to the longitude and latitude position information obtained by locating; obtaining a plurality of corresponding map resource original graphic blocks from a map server according to all graphic block numbers obtained by calculation; and splicing the map resource original graphic blocks into a picture for a user to browse, and locally storing the obtained map resource original graphic blocks for offline use. According to the realization system and method, service encapsulation is provided for the underlying map; an upper layer does not need to pay attention to which map resource is applied; a developer does not need to pay attention to map implementation and only needs to pay attention to provision of applications for the user; and the user can perform switching according to map quality and demands provided by different map resources, so that the expansibility is high and the user experience is good.
Description
technical field [0001] The invention relates to the technical field of map resource development and application, in particular to a system and method for realizing map resource localization. Background technique [0002] With the launch of Google Earth in 2005, people have a more clear and accurate tool to understand our earth. At the same time, it also led a group of panorama satellite image providers to develop and apply map resources and provide them to Internet users. [0003] Now users can conveniently browse map resources provided by different companies (google, bing, Gaode, Baidu, Tencent) through browsers. These services also provide corresponding SDK interfaces for users to develop and call. Conveniently calling server interfaces can make Users can also provide map services for their own application clients. [0004] Although it is convenient to use the SDK provided by the manufacturer for development, it is necessary to accept the advertisement pop-up information...
