[0002] Spatial data is a quantitative description of objects and phenomena in the real world that have locational significance. Today, in networked geographic information systems (GIS), spatial data, as the foundation of the entire information system, has a wide range of applications in production and daily life. Because data must be transmitted over a network, data security is a critical issue in GIS.

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0024] The embodiment of the present invention provides a method for accessing spatial data, such as Figure 1 As shown, the method includes the following steps:

[0025] Step S101: When a user's access request for spatial data is received, the user's identity information is determined. Data users have varying levels of access requirements for spatial data. Low-level data users are often not permitted to access high-level spatial data. Therefore, when a data user's access request for spatial data is received, the user's identity must first be determined to further determine the corresponding access rights. Spatial data represents a quantitative description of objects and phenomena in the real world that have location-based significance.

[0026] Specifically, spatial data is managed in an independent subnet to ensure that only authorized users can access the network, thereby preventing spatial data leakage. In an embodiment of the invention, authorized user information is managed through VPN technology. Only users who have passed VPN authentication can access the network. In other words, VPN authentication can determine the identity information of users accessing the network.

[0027] Step S102: Determine whether the user has access rights based on the user's identity information. Specifically, for spatial data storage space, the identities that can access it will be restricted, that is, not every identity role can access the spatial data. Therefore, first determine whether the user has access rights to the spatial data based on the user's identity information. For example, for a school's plot layer data, only administrators with the school's certification have access rights. When an access request from a student or teacher is received, it can be determined that the user does not have access rights based on the user's identity (student or teacher).

[0028] Step S103: When the user has access rights, the user's identity information is matched with the preset spatial data usage configuration information, and the preset spatial data usage configuration information includes identity information and spatial data usage permission information corresponding to the identity information. Specifically, different identity information corresponds to different access rights. When the user has access rights, the usage configuration permissions of different data in the accessible space must be further determined, that is, the user's identity information is matched with the identity information in the accessible space and the usage permissions of the spatial data corresponding to the identity information, that is, the preset spatial data usage configuration information. Specifically, in any space, the accessible identity information is pre-configured and the corresponding spatial data usage permission information is matched to the identity information.

[0029] Step S104: Determine the user's spatial data usage permissions based on the matching results. Specifically, if the matching results are consistent, the user can access the matching spatial data in the space. For example, in a space T, if spatial data usage permission B is matched for identity A, then if user A is the user, after matching, user A can access spatial data B in space T.

[0030] The method for accessing spatial data provided by the embodiment of the present invention matches and determines the corresponding accessible spatial data based on the user's identity information, thereby improving the spatial data content with a higher level of response according to different user needs and improving the security, controllability and accuracy of access.

[0031] As an optional implementation of an embodiment of the present invention, the preset spatial data usage configuration information includes the usage permission information of different spatial units for users with different identities; when receiving the user's access request to the spatial data, before determining the identity information of the user, the method further includes: cutting the spatial data to be accessed according to the target division conditions to obtain multiple spatial units; determining the data attribute information of each spatial unit according to the data type contained in each spatial unit obtained by the division; and configuring the identity information of the accessible user corresponding to each spatial unit according to the data attribute information. Specifically, in actual system applications, different system users have different data viewing ranges, and the data space ranges provided by the system are different. In an embodiment of the present invention, cutting the spatial data to be accessed according to the target division conditions can ensure that the system user can only access the spatial data within the authorized space range. Moreover, through cutting, the data space unit division can be completed in advance, which greatly improves the loading speed of the spatial data and improves the user's work efficiency. Among them, the data attribute information can represent attributes such as name and type.

[0032] For example, if the spatial data is parcel layer data, it can be segmented according to administrative division codes to obtain multiple spatial units, where the parcel layer data in each spatial unit corresponds to the same administrative division code. Then, the data attributes of the spatial unit are determined based on the type of parcel layer data contained in each administrative division code. The spatial data is then assigned user identity information based on these data attributes, further determining the user's access rights to the spatial range.

[0033] For example, if the plot layer data contained in the administrative division code A is geographic location data, then the attribute information is determined to be geographic location information, and then the identity information of the corresponding accessible user is configured as role B for the geographic location information. In this case, only users with identity information B can access the spatial data whose corresponding attribute is geographic location contained in the administrative division code A.

[0034] As an optional implementation of an embodiment of the present invention, after determining the data attribute information of each spatial unit according to the data type contained in each spatial unit obtained by division, the method further includes: processing the data attribute information of the spatial unit to obtain a corresponding MD5 code. Specifically, after the spatial data to be accessed is cut according to the target division conditions, it is also necessary to process the data attribute information of the corresponding spatial unit after cutting using the MD5 information digest algorithm and generate a corresponding MD5 code. In this way, the spatiotemporal consistency of the spatial data can be guaranteed. Among them, the MD5 information digest algorithm is used to ensure the complete and consistent transmission of information. In an embodiment of the present invention, the MD5 code is used to distinguish the spatiotemporal consistency of two spatial layers (storing corresponding spatial data), so that the system (the system storing spatial data) can arbitrarily read historical spatial data from different periods.

[0035] For example, in an actual project, a layer of data may contain a lot of historical data during the project implementation process. Therefore, the use of MD5 code can ensure the temporal and spatial consistency of the data used in a certain period of time.

[0036] As an optional implementation of an embodiment of the present invention, the spatial data usage permission information also includes usage permission information for spatial data layers by users of different identities and / or usage permission information for spatial data of different data attributes by users of different identities, wherein different spatial data layers correspond to different spatial data. First, in actual use of the system, there are often multiple spatial data, and the spatial data provided for different types of users are also different, that is, different spatial data layers correspond to different spatial data. Specifically, in an embodiment of the present invention, the system provides spatial data to system users in the form of map services, and each spatial data corresponds to a map service layer. Based on the user's identity, the map service layer that the user can access is authorized to prevent the user from obtaining spatial data that is not allowed to be obtained, that is, the spatial data usage permission information also includes usage permission information for spatial data layers by users of different identities.

[0037] Secondly, a spatial data layer often has as few as a few, or as many as dozens or even hundreds of attribute fields. Depending on the user's level, the data fields they can access are also different, and high-level attribute information is often not accessible to low-level users. Therefore, in an embodiment of the present invention, it is also necessary to grant permissions to the spatial data attribute fields accessible to users to ensure that users do not access attribute data outside of their permissions. That is, the spatial data usage permission information also includes the usage permission information of users of different identities for spatial data with different data attributes.

[0038] As an optional implementation manner of an embodiment of the present invention, when the spatial data usage permission information includes usage permission information of spatial data layers for users with different identities, usage permission information of spatial data with different data attributes for users with different identities, and usage permission information of different spatial units for users with different identities; after determining the spatial data usage permission of the user based on the matching result, the method further includes: loading the matched spatial data layer to the user; when obtaining keyword information of the spatial unit uploaded by the user, filtering and loading the spatial data of the corresponding spatial unit in the spatial data layer; when obtaining attribute information of the data type uploaded by the user, filtering and loading the spatial data of the corresponding attribute in the spatial unit according to the attribute information of the data type.

[0039] Specifically, after determining the user's spatial data usage permissions, the system first loads the matching spatial data layer for the user. Secondly, when the user loads the spatial data layer, the system filters the loaded spatial data layer based on the spatial unit keyword information uploaded by the user (such as the administrative division code), and only loads and displays the spatial data within the spatial range that the user has permissions to use. Then, when the user queries the spatial data attribute information, the system filters the spatial unit based on the attribute field permission information that can be queried, that is, based on the attribute information of the data type, and finally returns the corresponding attribute information (spatial data permissions for the corresponding attributes).

[0040] In one embodiment, if Figure 2 As shown, the access requirements of roles A, B, and C are received, and the user information with access rights is determined through VPN verification, and then uploaded to the server. The permission information of the corresponding accessible spatial data layer is matched according to the user identity information, and the accessible spatial layer data is determined. Secondly, the corresponding spatial range access rights are matched according to the user identity information, and the layer data of the accessible spatial unit in the accessible spatial layer data is determined. Finally, the limited attributes of the accessible layer data of the spatial unit are determined according to the attribute information of the data type uploaded by the user.

[0041] For different user roles, the data acquisition scope is set in multiple dimensions through spatial data layers, spatial scope and attribute field permissions, which not only ensures the confidentiality requirements of spatial data, but also makes the data circulated within a controllable range, increasing the designability and integrity of the program.

[0042] The spatial data is divided into spatial ranges according to the map patches, and the geometric cutting algorithm is used to accurately calculate the spatial range of the business data. The cross-range business data is divided into precise proportions to provide accurate data for the summary statistics of the business, making the decisions based on spatial data more accurate and instructive.
