Problems solved by technology

[0003] However, the above-mentioned technical system has the following deficiencies: 1. In the online mode, during the planning and investigation of civil servants, the limitation of network bandwidth and stability may cause difficulties in data transmission and display, and the amount of planning-related data is large, and the mobile data consumption is high. Greatly increased business costs
2. There is a problem of inconvenient data update in offline mode

Embodiment 1

[0034] Such as figure 1 As shown, the present embodiment 1 provides a geographic data update and maintenance system, including: a map update preprocessing module for updating and preprocessing geographic data; a database located at the server end and connected to the map update preprocessing module to be suitable Corresponding updating is performed through the preprocessed geographic data; and the mobile terminal downloads and updates the geographic data.

[0035] Wherein, the mobile terminal is for example but not limited to smart terminals such as mobile phones and IPADs.

Embodiment 2

[0037] Such as Figure 2 to Figure 4 As shown, on the basis of Embodiment 1, Embodiment 2 also provides a working method of a geographic data update maintenance system, that is, the method for updating and preprocessing geographic data in the map update preprocessing module includes: performing geographic data Quality inspection; change the coordinate system to an encrypted GCJ-02 coordinate system; use the byte replacement method to encrypt the map tile data in tpk format; and use the AES encryption algorithm to encrypt the data stored in the database. This encryption uses a simple byte replacement algorithm to encrypt the index files and data configuration files (map tile data related files) of compact slices, without affecting the display efficiency of offline maps.

[0038] Quality inspection of geographic data, that is, whether the coordinate range is out of range, coordinate system inspection, whether there is a polyline in the detailed planning data, and layer name insp...

Abstract

The invention relates to a geographic data updating and maintenance system based on a mobile planning application system. The geographic data updating and maintenance system comprises a map updating pretreatment module, a database and a mobile terminal, wherein the map updating pretreatment module updates and pretreats geographic data, the database is located at a server end and connected with themap updating pretreatment module and is suitable for correspondingly updating pretreated geographic data, and the mobile terminal downloads and updates the geographic data. The geographic data updating and maintenance system has the advantages that map tile data is encrypted by adopting a byte substitution method, the speed of map accessing and browsing is guaranteed on the basis that data safetyis provided; multi-version data management and multi-state multi-time phase data mobile application are achieved; the mobile terminal updates data in an online mode, and data application is conductedin an off-line mode so that data can be updated conveniently, and the fluency of data application can also be guaranteed.

Description

technical field [0001] The invention relates to the application field of mobile geographic information systems, in particular to a practical mobile planning application system geographic data update and maintenance system, which can be applied to mobile geographic information system software running on mobile phones, tablet computers and other devices. Background technique [0002] According to different data service methods, the application mode can be divided into two types: offline mode and online mode. Offline mode: Offline mode data is stored in the mobile terminal, and functional services such as acquisition, display, query, retrieval and analysis of spatial information are all completed by the mobile terminal without relying on the background server. Online mode: The mobile terminal device is connected to the application server through the wireless network, and can obtain the required data in real time. [0003] However, the above-mentioned technical system has the f...
