Abstract
The invention discloses a spatial data correlation method and system. The spatial data correlation method comprises the steps of: querying and displaying correlated spatial data according to attribute information of a login user; and determining an object to be correlated from the spatial data, establishing a correlation relationship with the correlated object and displaying the correlation relationship. According to the spatial data correlation method and system disclosed by the invention, through displaying the spatial data and the established correlation relationship, the correlation relationship is visually and clearly shown, so that spatial information is more simply and conveniently mined and applied and the work quality and efficiency of mangers are improved.
Description
Technical field
The present invention relates to a kind of database technology, relate in particular to a kind of spatial data correlating method and system.
Background technology
Along with the continuous expansion of database field and deepening continuously of service application, it is complicated day by day that the incidence relation between spatial data becomes.For its clear description is also intuitively represented, press for its incidence relation is carried out visual expression, and fail to consider this point in the existing system substantially so that carry out business function, the spatial data association has been subjected to certain constraint, is unfavorable for the analysis of operational space data.
Establishment and the definition of incidence relation can only be realized by the mode of manual input database executive routine by the minority professional between a plurality of figure layer data in the spatial database, and this just has certain requirement restriction to operating personnel's professional ability.
Summary of the invention
The objective of the invention is to, a kind of spatial data correlating method and system are provided, the incidence relation of visual spatial data improves managerial personnel's work quality and efficient.
For achieving the above object, according to an aspect of the present invention, provide a kind of spatial data correlating method, comprising:
According to the attribute information of login user, inquiry also shows relevant spatial data;
Need to determine affiliated partner from described spatial data, the incidence relation of foundation and described affiliated partner also shows described incidence relation.
For achieving the above object, according to another aspect of the present invention, provide a kind of spatial data interconnected system, comprising:
Enquiry module is used for the attribute information according to login user, the spatial data that inquiry is relevant;
Module is set up in association, is used for need determining affiliated partner from described spatial data, sets up the incidence relation with described affiliated partner;
Display module is used for showing described spatial data and described incidence relation.
Spatial data correlating method of the present invention and system, by showing the incidence relation of described spatial data and foundation, show described incidence relation intuitively, clearly, make that the excavation of spatial information and application are more simple and easy to do, improve managerial personnel's work quality and efficient.
Description of drawings
Fig. 1 is the process flow diagram of spatial data correlating method embodiment of the present invention;
Fig. 2 is the structural drawing of spatial data interconnected system embodiment of the present invention.
Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
The present invention sets up incidence relation between each isolated GIS figure layer, and the technology of association service interface externally is provided, for excavation and the application of spatial information provides a kind of simple and easy to do means.
Method embodiment
As shown in Figure 1, spatial data correlating method embodiment of the present invention may further comprise the steps:
This operation specifically comprises: essential information, manifestation mode and the related classification of described incidence relation are set,
Wherein, essential information comprises: the title of incidence relation, code, description, related field, the update strategy of parent table, the deletion strategy of parent table, the mode of operation of parent table and the mode of operation of sublist etc.; Manifestation mode comprises: types of presentation and performance information etc.; In addition, other classification level of association class also further being set selects;
The spatial data correlating method of present embodiment by showing the incidence relation of setting up, is showed described incidence relation intuitively, clearly, makes that the excavation of spatial information and application are more simple and easy to do, improves managerial personnel's work quality and efficient.
Preferably, present embodiment also comprises: step 114 exports to incidence relation in the XML file.Utilize the XML file that the incidence relation of setting up is stored, be convenient to later calling.
System embodiment
As shown in Figure 2, spatial data interconnected system embodiment of the present invention comprises:
Preferably, present embodiment also comprises: derive module 208, be used for described incidence relation is exported to the XML file.
Wherein, module 204 is set up in association, concrete essential information, manifestation mode and the related classification that is used for arranging described incidence relation.
The spatial data interconnected system of present embodiment by showing the incidence relation of setting up, is showed described incidence relation intuitively, clearly, makes that the excavation of spatial information and application are more simple and easy to do, improves managerial personnel's work quality and efficient.In addition, utilize the XML file that the incidence relation of setting up is stored, be convenient to later calling.
It should be noted that: above embodiment is only unrestricted in order to the present invention to be described, the present invention also is not limited in above-mentioned giving an example, and all do not break away from technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in the claim scope of the present invention.
