Embodiment Construction

[0027] The present invention aims to propose a method for realizing fast loading of map data, so as to solve the problems of slow map loading and overlapping of data elements in the traditional technology when the map is roaming or zooming.

[0028] Below in conjunction with accompanying drawing, scheme of the present invention will be further described:

[0029] see figure 1 , the method for realizing fast loading of map data among the present invention comprises the following implementation steps:

[0030] a. Establish map data acquisition service interface;

[0031] b. Set the map boundary change monitoring event to monitor the change of the map boundary;

[0032] c. Determine whether the map boundary change is greater than the threshold X, if so, enter step d, otherwise, return to step c;

[0033] d. Call the map data acquisition service interface to process the map element data according to the parameters passed in from the calling end, and obtain the final set of elem...

Abstract

The invention relates to a map zooming technique, discloses a method for rapidly loading map data, and solves the problems of slow map loading and data element overlapping in map roaming or zooming in a traditional technique. The method includes the steps: a, building a map data acquisition service interface; b, setting a map boundary change monitoring event for monitoring map boundary change conditions; c, judging whether a map boundary change is larger than a threshold value X or not, entering the step d if the map boundary change is larger than the threshold value X, and returning to the step c if not; d, calling the map data acquisition service interface to process map element data according to parameters transmitted by a calling end to obtain an element set finally meeting conditions; e, drawing the map element data in the element set finally meeting the conditions on a map. The method is applicable to map roaming or zooming.

Description

technical field [0001] The invention relates to map scaling technology, in particular to a method for realizing fast loading of map data. Background technique [0002] In recent years, location-based services have been continuously developed, and more and more websites and mobile application software provide related location-based service functions, which include: location check-in, information query, making friends, etc. [0003] However, due to the influence of network speed, computer configuration, and embedded processor speed, the loading of data elements will be affected to a certain extent during map roaming and map zooming, which makes the user experience effect not very ideal. The intuitive performance is that the map loads slowly. , data element overlap and so on. [0004] Therefore, seeking a method to realize fast loading of map data has become a research hotspot in map zooming technology. Contents of the invention [0005] The technical problem to be solved b...
