If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.
Referring to fig. 1, a first embodiment of the present invention provides a digital earth display method including the steps of:
step S100, acquiring a service request of a user;
step S200, acquiring a user ID according to the service request, and acquiring authority information of the user according to the user ID;
step S300, obtaining interest point information according to the service request, and judging whether the user has the viewing authority for the interest point according to the authority information and the authority label of the interest point in the interest point information;
and step S400, displaying the interest points of which the user has the viewing authority.
In step S100, a user inputs a place in a client search box or clicks on an area in the digital earth or zooms on an area of the digital earth, intends to view geographic information of the place or area, and then generates a service request. The service request is sent to the server side through the network. The server side obtains a service request of a user.
In step S200, a service request includes a user ID, and the server extracts the user ID from the received service request; determining the authority group of the authority database where the user ID is located, and acquiring the authority information of the user; wherein the permission database has a plurality of permission groups in which the user ID can exist.
For example, in the rights database, there are five rights groups, including group one, group two, group three, group four, group five. User a can exist in both group one and group two. User B can exist in group one and group three. Defining a group one as a basic authority, and the registered users exist in the group one.
In step S300, a service request includes the information of the point of interest, and the server extracts the information of the point of interest from the received service request; the point of interest information corresponds to a geographic name of a place or area that a user intends to view by entering the place or clicking or zooming on an area of the digital earth in a client search box;
and finding the interest point information in the permission database, and confirming a permission label corresponding to the interest point information, wherein the interest point information corresponds to the permission label from 1 to n. For example, if one piece of point of interest information has a tag of "group two" and a tag of "group three", the user existing in group one does not have the viewing right, the user a existing in group two has the viewing right, and the user B existing in group three also has the viewing right.
For another example, if one point of interest has three-dimensional map information, solid picture information, nearby scene information, and internal structure information, the three-dimensional map information and the nearby scene information have "group two" and "group three" tags, and the solid picture information and the internal structure information have "group three" tags, then user a only has viewing permissions for the three-dimensional map information and the nearby scene information, and user B has viewing permissions for the three-dimensional map information, the solid picture information, the nearby scene information, and the internal structure information.
In step S400, the server encrypts the interest points with the viewing right, and sends the encrypted interest points to the client; and the client receives the interest points sent by the server, decrypts the interest points and displays the decrypted interest points on the terminal. The geographic information and the user information of the interest point of the user can be directly acquired by preventing the interest point from being intercepted by people in the transmission process through an encryption means, and the safety is improved. Specifically, the encryption method employs DES encryption.
Further, the digital earth display method further comprises: and establishing a permission database according to the personal information provided by the user registration. For example, if a user provides personal information that the nationality is japan, the user has no viewing right for the geographical information of detailed streets in a non-japanese area. The detailed street has a label of group three and the user is not present in group three in the permissions database.
In the embodiment, the digital earth is managed and displayed according to the authority, so that the geographic information is protected, the geographic data sharing capability is improved, and the manpower and material resources are saved; the map resource authority control management precision is improved, and a user can manage and control map resources more conveniently.

and the display module 50 is used for displaying the interest points of which the user has the viewing right to the user.
According to the second aspect of the present invention, the second obtaining module 20 performs the following steps to obtain the authority information of the user according to the user ID:
determining the authority group of the authority database where the user ID is located, and acquiring the authority information of the user; wherein the permission database has a plurality of permission groups in which the user ID can exist.
