In a preferred embodiment of the present invention, the layer data construction module 3 includes a multi-source data fusion unit 31, which is used for performing multi-source data fusion on professional layer data with different sources, structures and formats to perform centralized management.
In a preferred embodiment of the present invention, the multi-source data fusion method includes:
the method comprises the following steps of data sharing and exchange, data processing, multi-precision data fusion, data comprehensive management, data version management and data maintenance mechanism management.
Specifically, in this embodiment, the data sharing and exchanging interface of the data sharing and exchanging is implemented by using a unified data exchanging system. The data exchange is an important node and a support system in an intelligent management platform architecture, is an effective carrier for landing of regional data management measures, is an important link of an ecological island multilayer data service system, is a rapid and comprehensive data pool, can realize decoupling between a data supply system and a data warehouse, promotes formation and use of incremental or standardized data by extracting and refining common data processing activities of all business systems, releases the pressure of a data sharing system, and meets the individualized data extraction requirements of all systems. The data sharing exchange interface needs to realize the functions of passive pushing and active grabbing. The passive pushing is to passively push data to a data warehouse in a region center from an external system according to a predefined data interface and an appointed time point, and a flag bit is set after the pushing is finished to tell the completion condition of the data warehouse. The active capture is that a data interface is well defined in a data warehouse, and when business needs, the data warehouse actively captures relevant business data into a business system.

In this embodiment, the data processing information sources are as follows:
from the surveying institute: the part of data is generally in a shape layer form, and the processing mode is as follows:
layering: and re-layering or merging the layers according to the data dictionary principle.
Type conversion: if the layer types are not matched, the processing such as closing, dividing and the like of the graph is carried out to form the corresponding types.
And (3) optimizing: node optimization, topology establishment and the like.
Adding attributes: add or modify the corresponding attributes.
The method is from professional units and mainly comprises the following cases:
the provided data is in shape layer form, and the processing mode is mainly as follows:
layering: and re-layering or merging the layers according to the data dictionary principle.
Type conversion: if the layer types are not matched, processing such as closing and dividing of the graph is carried out, and a corresponding type is formed.
Adding attributes: add or modify the corresponding attributes.
The provided data is in a table form with address information, and the processing mode mainly comprises the following steps:
the standard content is as follows: the "address" information in the specification table.
Spreading points: and (4) using a professional address point scattering tool to generate point image layers in batches according to the addresses in the table.

Adding attributes: add or modify the corresponding attributes.
In this embodiment, how to uniformly display data with different precisions is a technical problem to be solved by the technical scheme. The technical scheme adopts the advanced data fusion technology to realize the fusion of multi-precision data: the fusion between vector data is the most widely applied spatial data fusion form, and is also the key point of spatial data fusion research. At present, vector data fusion methods are various, wherein the most important and widely applied method is to firstly convert a data format, namely fusion of a spatial data model, then correct a geometric position, and finally reclassify, combine and uniformly define each element of map data again. Geometric position correction for data of the same coordinate system and scale, the accuracy of the data may differ due to technical, manual or frequent data transformations and even due to factors of different software. In the fusion process, the geometric position needs to be unified. If the requirement on the precision is not high, in order to improve the working efficiency, the geometric position of another type or several types of data should be corrected within an allowable range based on the data precision of the current system. For example, in order to obtain higher precision, data with low precision should be corrected with respect to data with high precision. And (4) comprehensively accepting or rejecting data. Space vector data with different formats in the same area should be comprehensively accepted to relate to the problem of repeated representation of the same element. There are generally the following principles: the detailed replacement is simple, the replacement with high accuracy is low, and the replacement with a new one is old, but some cases should be comprehensively selected as appropriate in order to highlight a certain special element or to meet a certain need.
In this embodiment, the data integrated management implements unified management and control of the database, so as to ensure the security and integrity of the database. It provides multiple functions that allow multiple applications and users to build, modify and query databases in different ways, either at the same time or at different times. A sophisticated database management function may specifically include the following:

The protection of the database is achieved by 4 aspects: backup and fault recovery of the database, concurrent control of the database, integrity control of the database and security control of the database.
In this embodiment, the data version management process includes: the user can create a special folder in the version control function for storing various documents generated in the data modification process, and for each document, a plurality of versions of the document can be stored for reference at any time. After the system passes the authority control, the user with the authority can borrow (download) the project first, and after the modification is completed, the project is archived again and the original project content is covered. The processing may also be limited separately for modification rights and for approval of archive rights after modification. The same project can be saved as a new version after being modified, and multi-version management is carried out. The version management function can completely save all modification records of each data in data maintenance, so that the version control function can be fully utilized to effectively manage the data maintenance and modification. The version upgrading of the graph document is realized through check-in and check-out operations, the management of the version can be realized, and the browsing and tracing of the historical version can be realized.
