Problems solved by technology

[0004] (1) Existing technical methods rely more on knowing the spatial index area in advance;
[0005] (2) Existing technical methods have fixed spatial area division and lack flexibility;
[0006] (3) The existing technical methods need to re-establish the entire spatial index structure after the amount of spatial data changes, wasting a lot of computing time;
[0007] (4) Existing technical methods are mainly based on desktop computers with better hardware performance, but lack adaptability on mobile devices;
[0008] (5) Due to the consideration of the desktop computer as the platform, the existing technical methods allow spatial objects to have different degrees of repeated storage, which wastes a certain amount of storage

Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] Invention of mobile geographic information spatial indexing method is mainly divided into three steps:

[0043] (1) Storage of mobile geographic information spatial data; (2) Establishment of mobile geographic information spatial index structure; (3) Design of mobile geographic information spatial index method.

[0044] 1. Storage of mobile geographic information spatial data

[0045] The storage of mobile geographic information spatial data mainly includes the storage of graphic data and attribute data.

[0046] (1) Local files

[0047] The graphic data of this indexing method is stored in the form of local files. A file is a collection of records of the same nature. Since the data volume of a file is large, it is generally stored on an external storage, so a file may refer to a collection of data stored in an external mediu...

Abstract

The invention discloses a mobile geographic information spatial index method, which is characterized by mainly comprising the following three steps of: (1) storing mobile geographic information spatial data; (2) establishing a mobile geographic information spatial index structure; and (3) designing the mobile geographic information spatial index method. The method has the characteristic of high storage efficiency, is easy and convenient to use, and can be widely applied to the fields of telecom value-added services and computer application technologies.

Description

technical field [0001] The invention belongs to the technical fields of telecommunication value-added services and computer applications, and in particular relates to a method for spatial indexing of mobile geographic information. Background technique [0002] The background of the traditional spatial index theory is that the resource-rich PC or server has hardware conditions, and the storage capacity, CPU calculation speed, screen display, wired power supply, etc. are very different from mobile devices. If these spatial indexing technologies are directly applied to mobile GIS, the performance often cannot meet the original design requirements. [0003] Disadvantages of existing technology: [0004] (1) Existing technical methods rely more on knowing the spatial index area in advance; [0005] (2) Existing technical methods have fixed spatial area division and lack flexibility; [0006] (3) The existing technical methods need to re-establish the entire spatial index struc...
