Embodiment

[0049] Examples, see figure 1 , the method for organizing geographical data provided by the embodiment of the present invention includes the following steps:

[0050] S101: Obtain a data source;

[0051] Wherein, the data source may be data downloaded from the network, or data stored locally, and in practical applications, it may be obtained accordingly as required.

[0052] S102: Implement an interface for the data source according to a predefined specification, and generate a layer according to the data source data;

[0053] Different from the map layering method in the prior art, the map layering method adopted in the embodiment of the present invention is to define the interface specification in the system design stage, as long as the data source that realizes the interface of the specification can be added to the system; therefore When designing a map, you can determine which data needs to be added according to the needs of the actual business, and then after obtaining ...

Abstract

The invention discloses a method for organizing geographic data, comprising the following steps: a data source is acquired; an interface is provided for the data source according to a predefined specification, and image layers are generated according to the data source; a pointer pointing at all the image layers is generated; commands are sent to the image layers by a hinge structure; and the commands are executed by the image layers after the commands sent by the hinge structure are received by the image layers. The invention also discloses a system for organizing geographic data. With the invention, the data source can be any source of any type and can be added to the system to serve as the image layers of the system if only the interface is provided, which fully embodies the flexibility and the expandability of the system.

Description

technical field [0001] The invention relates to the technical field of geographic information processing, in particular to a method and system for organizing geographic data. Background technique [0002] Electronic map technology is a comprehensive technology that integrates many modern technologies such as geographic information system technology, digital mapping technology, multimedia technology and virtual reality technology. An electronic map is a modern information product that uses a visual digital map as the background and uses multimedia such as text, photos, charts, sounds, animations, and videos to display the comprehensive appearance of cities, enterprises, and tourist attractions. It is stored in the external memory of the computer, disseminated in the form of CD-ROM, network, etc., and provided to the public in the form of desktop computer or touch screen computer. [0003] The update pace of map data is greatly affected by the social economy. For example, for...
