Background technique
With the deployment and implementation of geographic information data sharing platform, figure platform based on B/S framework, data update
Difficult problem is increasingly prominent, especially declaration, the data of permission class such as sell, transfer, need to accomplish real-time spatial geography data
Update operation.
The predominantly artificial backstage of operation is updated by hand currently based on system datas such as the data sharing platform of B/S, a figures
Tupe, process are as follows:
Into background service management, stop and the service of deleting.
Into GIS desktop programs, data update is carried out by hand.
Into background service management, Map Services are issued again and are sliced.
The pure manual operations of entire data updating process may need to consume 0.5-2 hours inside comprising the slice time.
But above-mentioned existing backstage craft spatial data renewal model, need administrative staff to have certain GIS desktop
Application power, while pure manual operations is easy error.Service stopping in data updating process, user can not access.Influence space
The practicability of data sharing platform.Entire renewal process is actually once re-operating for map service publication.Time-consuming compared with
It is long, higher cost.
The present invention is directed to the problems such as map data update under BS technology is difficult, and operating process is complicated, by making rational planning for, mentions
Out and the data dynamic update system based on B/S framework is built, updates map datum for announced Map Services dynamic, if
Flexible structure is counted, user's operation is simple and convenient.
Summary of the invention
The object of the present invention is to overcome the problems of the prior art, provides a kind of spatial data based on B/S framework
Data are uploaded to server by browser by dynamic update system, user, are realized that the dynamic of spatial data updates, are improved and use
Family experience, mitigates the workload of system maintenance personnel, provides skill for Spatial Data Sharing platform or a figure comprehensive management platform
Art support.
To realize above-mentioned technical purpose and the technique effect, the invention is realized by the following technical scheme:
A kind of spatial data dynamic update system based on B/S framework, the system include that GIS Simulation spatial service management end and web are answered
With client, in which:

Reason end includes data publication module and service management module, and user issues spatial data by the data publication module and takes
Business, user issue the Map Services of WMS, WFS, WMTS of compound OGC standard by the service management module, and the GIS is empty
Between service management end further include having slice management module, be used for the sectioning of to map service execution；
The web applications client is integrated in comprehensive management of spatial data platform or a figure comprehensive management platform, and provides
Interface and corresponding upload button are passed, user needs the file updated by clicking upload button, selection, uploads and execute data more
Newly, updated map datum figure layer is directly returned after data are updated successfully.
Further, the enterprise-level database of GIS Simulation spatial service management end connection include ORACLE database,
SQLServer database and PostgreSql database.
Further, the spatial data services include platform service management, platform service registration, local service publication,
Service uses audit and registration service application approval.
Further, user also supports ArcGIS Server by the Map Services that the service management module is issued
The Map Services of Rest style.
Further, the slice management module to map service execution sectioning include setting to slicing parameter,
The management of section protocol and the management for being sliced path.
Further, user selects to need the file format updated to include shapefile format or coordinate txt format.
Further, which further includes spatial data dynamic more new technological process comprising following steps:
Step 1) carries out the quality of data inspection of spatial data, is directly entered service operation number by the data of quality of data inspection
It completes to update work according to library, into next step, not by the delta data of quality of data inspection, then carries out pop-up prompt；
Step 2 periodically or is automatically called space FML by data more new demand by the delta data after quality of data inspection
The tool box ETL is extracted from the remittance of service operation data library, conversion and load data form data source to be updated；
Data source to be updated is updated to GIS spatial data library by step 3), and writes the result into Update log, is completed to space
The update work of data.
Further, in the step 3), before data source to be updated is updated to GIS spatial data library, to step
Data source to be updated after rapid 2) middle conversion carries out quality of data inspection again, and inspection is updated to the space GIS number after passing through again
According to library, to improve the quality of data, it is ensured that the validity of update.
The beneficial effects of the present invention are:
Spatial data dynamic update method of the invention has operation threshold low, without installing and using GIS desktop software, is not necessarily to
Stop background service, update high-efficient advantage, and applied widely, is applicable to Spatial Data Sharing platform and a figure
Equal comprehensive management of spatial data system.
Detailed description of the invention
Fig. 1 is that spatial data of the invention updates flow chart.
