Description
One, technical field
The present invention relates to map making, particularly numerical map and GIS (GIS-Geographic Information System, lower same) the middle one used
Linkage updates the method for geography information and map making data.
Two, background technology
Currently geography information and map making data are the most individually updated, and to map cartographic data with file shape
Formula storage and renewal, owing to the renewal frequency of the two is inconsistent, cause the Up-to-date state between geography information and map making data
There are differences, data content there is also bigger inconsistent, had a strong impact on the use of user.Simultaneously as two kinds of numbers
According to the most individually updating, causing updating efficiency extremely low, operating cost is sufficiently expensive.
Three, summary of the invention
For above-mentioned situation, for overcoming prior art defect, the purpose of the present invention is just to provide a kind of linkage and updates geography
Information and the method for map making data, can effectively solve geography information and separate renewal with map making data, exist between data
Relatively make great difference, and the problem updating inefficiency.Its technical scheme solved is, relies on geography information and the map of integration
Geography information in cartographic data base, the most more new database, then according to key element level between geography information and map making data
Incidence relation, generates map making data corresponding in cartographic data, and the more new database that links for twice after changing, and it realizes step
Rapid as follows:
1, rely on production to process software original geography information is editted and updated, by nominal data change information, raw
Become change geographical information updating bag；
2, input change geographical information updating bag to integration geography information with map making data base, then update geography
Information database；
3, information realization automatic Symbolic geographical to change is uniquely identified according to the drawing display rule set up and key element
Join, derive from the cartographic data that makes new advances, it is achieved the first time of cartographic data tentatively links renewal；
4, integration geography information and the map making data base output map making after the most preliminary linkage updates
Data to map making processes software, and further optimizes editor, ultimately generates new drawing performance data；
5, change cartographic data is extracted according to exclusive identification code after drawing performance data being carried out quality examination, and by its warp
Edge fit enters integration geography information after processing and map making data base carries out cartographic data second time linkage and updates；
6, terminate.
Compared to existing technology, there is advantages that
1, geography information and map making data can synchronized update, it is ensured that the concordance of data；
2, update with change and geography information be updated with map making data by the pattern of linkage renewal, it is possible to increase
Production operation efficiency, reduces production cost；
3, change the pattern that tradition geography information produces with map making data, manages and update, set up brand-new life
Produce mechanism integrated with management；
4, the method is used in digital cartography system, by a large amount of it was verified that the method can be effectively to geography
Information and map making data carry out linkage and update, and improve geography information and the production of map making data and management level.

Five, detailed description of the invention
Below in conjunction with accompanying drawing to a kind of based on spatial simlanty the numerical map area pattern querying method of the present invention
Detailed description of the invention elaborates.
Be given by Fig. 1, the present invention through the following steps that realize:
1, rely on production to process software original geography information is editted and updated, by nominal data change information, raw
Become change geographical information updating bag.
Each data production unit processes software and multi-source Up-to-date state data based on geography information production and is changed by data, adopted
Collection is edited and is reduced the staff the means such as process and carries out the production renewal of geographic information data, and the change information of nominal data, by data
Change information be divided into: increase, revise and delete three class change informations newly, by all changes information package generate change geography information
Update bag, with GI0Represent the geography information set before updating, GI0={ g1,0, g2,0..., gM, 0, g1,0, g2,0..., gM, 0Table
Showing the geography information key element before renewal, m refers to update front geography information set GI0Middle geographic element number, with GI1Represent and update
Rear geography information set, GI1={ g1,1, g2,1..., gN, 1, g1,1, g2,1..., gN, 1Represent that the geography information after updating is wanted
Element, n refers to geography information set GI after renewal1Middle geographic element number, GI0After increase newly, revise and deletion etc. updates operation
Form GI1, then change geography information bag Δ GI is represented by:
Δ GI=GI1-GI0={ Δ g1, Δ g2..., Δ gp} (1)
Δg1, Δ g2..., Δ gpReferring to key element in change geography information bag Δ GI, p refers to change in geography information bag Δ GI
Key element number.
2, input change geographical information updating bag to integration geography information with map making data base, then update geography
Information database.
Namely input Δ GI to integration geography information and map making data base, in Δ GI key element with in data base
Original GI0Middle key element is associated by unique mark, after setting up incidence relation, according to the scope of Δ GI, creates corresponding number
According to copy as work storehouse, by work storehouse, Δ GI is submitted to integration data storehouse again after Δ GI storage quality passed examination complete
Become final renewal.
3, information realization automatic Symbolic geographical to change is uniquely identified according to the drawing display rule set up and key element
Join, derive from the cartographic data that makes new advances, it is achieved the first time of cartographic data tentatively links renewal.
After Δ GI enters integration geography information and map making data base, under regular drive is expressed in drawing, derive it
Corresponding cartographic data Δ MI1, it is achieved the first time of cartographic data tentatively links renewal, is represented by
ΔMI1={ Δ M1,1, Δ M2,1..., Δ MQ, 1} (2)
ΔM1,1, Δ M2,1..., Δ MQ, 1It is cartographic data Δ MI after linkage updates for the first time1Middle key element, q is Δ MI1
Middle key element number.
4, integration geography information and the map making data base output map making after the most preliminary linkage updates
Data to map making processes software, and further optimizes editor, ultimately generates new drawing performance data.
By MI0+ΔMI1It is distributed to map making and processes software, through drawing Automated generalization, optimize editor and the inspection of various quality
Look into, ultimately generate new drawing performance data MI1, it is represented by:
MI1=MI0+ΔMI2 (3)
MI0It is original cartographic data, Δ MI2={ Δ M1,2, Δ M2,2..., Δ MR, 2, Δ MI2Refer at Δ MI1Basis
On, through drawing Automated generalization, optimize the change cartographic data formed after editing, Δ M1,2, Δ M2,2..., Δ MR, 2It is Δ MI2In
Key element, r is key element number.
5, after drawing performance data being carried out quality examination, change cartographic data is extracted according to exclusive identification code, and by it
After edge fit processes, enter integration geography information and map making data base carries out cartographic data second time linkage and updates.
To MI1Change cartographic data, change cartographic data here is extracted according to exclusive identification code after carrying out quality examination
Refer to Δ MI2, and it is entered after edge fit processes integration geography information and map making data base carry out cartographic data second
Secondary linkage updates.
