Spatial Data Warehouse 106 is connected to second database interface 105, and the geodata that will import from the database 107 in the external world is built into Spatial Data Warehouse 106, preserves geodata, and wherein geodata is relevant with data message;
On-line analysis treating apparatus (OLAP device) 106 is connected to attribute data warehouse 102, according to the attribute data of the data message of preserving in the application demand analytic attribute data warehouse of being scheduled to, produces the analysis data of attribute data;
Data binding device 108 is connected line analysis treating apparatus 106 and Spatial Data Warehouse 104, sets up the geodata that the multi-dimensional relation table will analyze in data and the Spatial Data Warehouse and binds;
Geographic Information System (GIS) 110 is connected to data binding device 108, and the attribute data of the data message after will binding according to predetermined application demand analysis and relevant geodata are carried out visualization processing, export visual signal;
Output interface 112 connects Geographic Information System 110, with visual signal output.
It is the management of people information that a kind of typical case in the main application of the present invention uses, particularly to the collection and the tissue (at this moment, people information is exactly the data message in this kind application) of people information in a certain administrative region.Therefore, in this kind application of the present invention, an outstanding feature is: geographical location information is stable, constant substantially, and the information relevant with population (comprising personnel, incident, tissue and things) all may change along with flowing of population.Therefore, in this system 100, the database 103 in the external world that first database interface 101 is connected mainly is based on the database of population relevant information, such as personal information database, event information database, organizational information database, things information database.What in the example depicted in fig. 1, database 103 was selected is real population database, case database, industry unit data storehouse and target database.Attribute data warehouse 102 is exactly the data warehouse that is built as with artificial fundamental.The database 107 in the external world that second database interface 105 is connected mainly is based on the database of geodata, generally can comprise map data base, coordinate database, topographic database.What in the embodiment shown in fig. 1, extraneous database 107 was selected is large-scale map database, medium scale maps database and small scale map database.It is the data warehouse of fundamental that Spatial Data Warehouse 104 is built as with the geographic position.
For attribute data warehouse 102, owing to be with artificial fundamental, so quantity of information is huge, and rate of change is also very high.This makes the Data Warehouse amount very big, therefore need carry out detailed design and selection to the access path of data, such as can be designed as following mode: set up ascribed characteristics of population concordance list, by ascribed characteristics of population concordance list, the user can know all ascribed characteristicses of population such as his permanent resident population's information, emphasis people information, criminal's information at everyone, its similar axis, the informational linkage of all and relating to persons get up.
The method that attribute data warehouse 102 generates be with Various types of data by changing, that drawing-in system can be discerned, be in the database of platform with the oracle database.At different data layouts, system provides special crossover tool.For example, for the residence management data, system is by regularly changing the increment incremental data in the data warehouse over to real-time dual mode.To generate various metadata (comprising geocoding of getting in touch with electronic chart etc.) in translation data automatically, this is referred to as to control the storehouse.On the other hand, data warehouse is also according to the time of setting, regularly automatically to the data in the data warehouse classify, statistical work.The foundation of data warehouse is an existing technology, therefore is not described in detail the process of specifically setting up in attribute data warehouse 102 here.
Spatial Data Warehouse 104 be mainly used in the conversion of carrying out spatial data, and can be used to provide and being connected of attribute data.As top said, what preserve in the Spatial Data Warehouse 104 is geodata, the residing specific geographic position of certain specific people (perhaps relative incident, tissue, things) just in fact, therefore, what preserve in the Spatial Data Warehouse 104 is and the relevant geodata of people information (herein, people information promptly is an example of data message).
The geodata typical situation relevant with data message of preserving in the Spatial Data Warehouse 104 is map, the map that can comprise the different proportion chi, map can be the electronic chart (referring to comprise simple map datum) of simple form, and the electronic chart of simple form can be directly obtains from the database 107 such as the top listed external world.Map also can be the electronic chart that has increased adeditive attribute, such as the adeditive attribute that has comprised that coordinate and landform are such, just needs this moment second database interface, 105 connection coordinate database and topographic database to obtain coordinate and landform attribute.
Wherein, coordinate attributes can be provided by coordinate file, and coordinate file can be defined as follows: (x y) is converted to map projection's coordinate through map projection transformation by latitude and longitude coordinates, carry out two-dimentional Cartesian coordinates conversion then, finally store with sequential file mode.And the landform attribute can be provided by the ground shape file, and the ground shape file can be defined as follows: be made up of information such as the identification information of geodetic control point, precision, coordinate, elevations.
For map, because in Mapping departments, most map datum all is the CAD form, so must be through data-switching and geocoding.In addition, on the basis of translation data and geocoding, electronic chart by cartographic generaliztion and processing, has formed the spatial data of different scale engineer's scale owing to be subjected to field of view different with required engineer's scale.The effect that its is realized is, in system, according to the visual field amplify in other words, scaled down difference, the cartographic information that system shows is different; According to different message reference needs, the attribute information difference of demonstration.
In a kind of realization of the present invention, each geodata in the Spatial Data Warehouse 104 can adopt three following category informations to represent:
The geographical entity of a reality is represented in the plot;
Polygon, the geometric element of expression geographical entity;
Supplementary, the representation attribute data are through projection, connection, the pretreated result of grouping.
Represent that by three above-mentioned category informations the association between OLAP implementation space data warehouse 104 and the attribute data warehouse 102 can be arranged effectively.Equally, because the foundation of data warehouse is an existing technology, and Spatial Data Warehouse principle of design clearly here, therefore be not described in detail the process of specifically setting up of Spatial Data Warehouse 104 here.
When a specific application demand occurring, will handle (OLAP) device 106 by on-line analysis and the attribute data in the attribute data warehouse 102 be handled according to this application-specific demand.A kind of typical processing mode is: OLAP device 106 carries out projection, connection, grouping pre-service according to the requirement of this application demand to attribute data, obtain analyzing data, and be to analyze data to set up the view collection, wherein projection, connection, grouping pre-service are relevant with predetermined application demand, and the view collection is also relevant with the application demand of being scheduled to.
With the data acquisition of people information be organized as example, in data attribute warehouse 102, the data of a large amount of relevant people informations have been preserved again.They have been endowed different attributes separately, and ascribed characteristics of population concordance list can help to search the people information data with particular community.Such as, when a certain specific application demand requirement acquisition " permanent resident population/floating population " information, then OLAP device 106 can come people information is classified according to the attribute in the expression address in the people information data, grouping pre-service that Here it is.Again such as, one specific application demand requires to obtain " personal information relevant with an incident ", and then OLAP device 106 is understood according to the attribute of the presentation of events in the people information data and searched other key elements that all are associated with this incident: personnel, tissue, things.Wherein, key element " personnel " can directly obtain desirable result, and key element " tissue " and " things " also need OLAP device 106 further to searching their related key elements " personnel ", and this can be understood as and connects pretreated a kind of example.For another example, for some personnel, they have multiple identity, so in the attribute data warehouse, it is corresponding with them to produce a plurality of personal information data.Here, if there is a specific application demand to use these personal information data, OLAP device 106 also can be set up mapping relations, the pretreated example of projection that Here it is in all relate to same personnel's personal information data.
Pass through after the pre-service of various necessity again, just can obtain the analysis data corresponding to this application-specific demand, OLAP device 106 also can be set up " view collection " for above-mentioned analysis data, and " view collection " reflected through the analysis data after the pre-service.The main effect of " view collection " be used for Spatial Data Warehouse in geodata set up related.
As mistake described above, each in the geodata relevant with data message of preserving in the Spatial Data Warehouse 104 adopts three category informations to represent:
The geographical entity of a reality is represented in the plot;
Polygon is used for one of geometric element of representing geographical entity, is most important class data, is used for representing administrative area, land type etc. more;
Supplementary is illustrated in the line analysis treating apparatus attribute data is carried out projection, connection, the pretreated result of grouping.
Like this, supplementary in the geodata and the view collection of analyzing in the data are corresponding fully, and this has just set up the most basic related of attribute data warehouse and Spatial Data Warehouse.
Data binding device 108 among the present invention is connected the line analysis treating apparatus 106 and second database 104, on the basis of above-mentioned view collection and auxiliary data, sets up further that the multi-dimensional relation table will be analyzed data and geodata is bound.
With reference to figure 2, Fig. 2 shows the incidence relation synoptic diagram of the multi-dimensional relation table that data binding device 108 set up.
At first be most basic incidence relation, promptly view collection and supplementary is related.Attribute data warehouse 102 is associated with a supplementary 206 by the view collection 204 that pre-service has obtained the analysis data relevant with certain application demand 202, one these analysis data 202 of reflection.This supplementary 206 has been preserved projection, connection, the grouping pretreated result of this application demand to correspondence, and this supplementary 206 is used for the geodata in the representation space data warehouse 104.
Continuation is with reference to figure 2, when the attribute packet is drawn together pre-defined rule corresponding to a certain geographical entity, comprises pretreated treaty rule in the analysis data that it produced.At this moment, the related information that also comprises polygon and pretreated treaty rule in the multi-dimensional relation that the data binding device is set up.As shown in Figure 2, pretreated treaty rule 208 is associated with polygon 210.
When the attribute packet is drawn together the map identifier (MAPIDD) of geographical entity, comprise pretreated map identifier in the analysis data, then the multi-dimensional relation of data binding device foundation also comprises the related information of plot and pretreated map identifier.As shown in Figure 2, pretreated map identifier 212 is associated with plot 214.
In conjunction with top description, because each geodata in the space attribute database 104 all is to adopt three category informations: plot, changeable shape and supplementary are represented, therefore, when the map identifier of pre-defined rule that comprises geographical entity in the attribute data and geographical entity, just can between attribute data warehouse and Spatial Data Warehouse, set up multi-dimensional relation by the data binding device.Multi-dimensional relation can adopt the form performance of multi-dimensional relation table.
The effect of Geographic Information System 110 is, multi-dimensional relation table according to 108 foundation of data binding device, on the basis of the geodata relevant with data message of preserving in Spatial Data Warehouse, the output visual signals shows and the predetermined relevant data attribute of application demand.Here, made full use of the following characteristic of Geographic Information System 110:
Spatial visualization
Spatial visualization comprises the visual of space atural object contour feature.Infosystem is the computer simulation to real world, and Geographic Information System has then been given prominence to its simulation to the respective real-world spaces relation, makes that the state for each things in the space has an impression very intuitively.No matter be to show that on screen a width of cloth can stepless zooming and the map of information inquiry, still represent the relief block of a width of cloth three-dimensional, all make more directly perceived to the understanding of respective real-world spaces relation, specifically.
Spatial visualization also comprises having space visual with reference to the atural object of characteristics special topic attribute information.The spatial visualization function of Geographic Information System also comprises the graph visualization to space distribution atural object attribute information, this point is that a key character by Geographic Information System guarantees, be the integrated management that GIS has realized spatial information and attribute information, and can set up the contact between the two perfectly.For example, utilize the administrative map in a Zhang area, can from gis database, extract the statistics that quantity takes place for case involving public security in the different rows administrative division and criminal case etc., the computational analysis safety case, and specify the different pairing figure spot of color and filling mode display line administrative division (this is the association process of a dependency to the space on realizing) by certain graded index, the thematic attributive character of space atural object just can have space visual with reference to information by the realization of Geographic Information System instrument like this.
Steric direction
Utilize Geographic Information System, not only can scan the universe of survey region, can also utilize the basic functions that GIS provided such as convergent-divergent and roaming to be deep into more interesting areas and go research.A perfect Geographic Information System provides the spatial data library facility, makes to check the overall situation with small scale, checks the part with medium scale, checks thin portion with large scale.When engineer's scale constantly increases, represent to user's spatial information content and can bring in constant renewal in.For example affix one's name to the compass of competency when overall situation browsing a police, only need to show big global informations such as river, road and neighbourhood committee's scope, and, just need to show concrete space atural objects such as little road, sub-district, factory, public place of entertainment along with the continuous increase of engineer's scale.These to cartography in the notion of the cartographic generaliztion emphasized be similar.
The steric direction function of Geographic Information System can also obtain embodying from the space querying function.For example utilize the police to affix one's name to compass of competency figure, can find by space querying " *Factory ", and immediately the indication range of map is zoomed to all " *Factory " in the scope of space distribution, this is the embodiment of steric direction effect equally.
Spatial thought
The spatial database of Geographic Information System has also stored the spatial relationship between the atural object in the space descriptor of each atural object of storage, these characteristics provide the foundation for carrying out spatial analysis.The spatial thought of Geographic Information System will utilize the information of having stored in the GIS database exactly, by the instrument (for example, buffer zone analysis, stacked analysis) of GIS, generates the information that does not have storage in the GIS spatial database.Geographic Information System integrates many spatial analysis instruments, and secondary development tool is provided.When carrying out spatial analysis, the user is organized into a program (being the thinking that computing machine can be discerned and operate) with various analysis tools by the Professional Model of institute's research field, transfers to Geographic Information System and finishes, and the analysis result of spatial visualization is provided at last.The spatial thought function of Geographic Information System make we can spatial relationship, other type information system such as space distribution pattern and spatial development trend the task of can't finishing.
For the present invention, because OLAP device 106 and data binding device 108 provide the associate feature of attribute data warehouse and Spatial Data Warehouse well, and, what preserve in the Spatial Data Warehouse is geography information such as map, therefore for GIS 110, the visualization display of utilizing its function can be implemented in the attribute data on geography information (such as the map) basis well (is for example passed through segment, color, real attribute data such as histogram), according to the present invention, be to produce visual information to show the data attribute relevant and visual signals is outputed to output interface 112 with predetermined application demand.
For the present invention, in realization, further adopted the development approach of GIS member.The GIS member is a kind of new thinking and the method for just having risen recent years, and appearing at when having brought more wide application prospect for GIS of GIS member also brought brand-new development scheme; The RAD instrument of being familiar with the developer (as: Delphi, PowerBuilder etc.) is the basis, uses standard compliant GIS component development generalized information system, and can tight and other integration of information system.Utilize GIS component development generalized information system to overcome the drawback of traditional GIS development scheme, and promoted the application of GIS.Use the generalized information system of GIS component development to have following characteristics:
The GIS member is the entity of specific function, therefore can select the GIS member according to the needs of function, is standard with the demand that satisfies system, reduces the scale of system as far as possible.
The GIS member is according to standard (as CORBA or DCOM) exploitation, so the GIS member can be in developing instrument RAD (as DELPHI, POWERBUILDER etc.) lining use fast.Utilize these instruments GIS function and MIS function can be integrated in the application program, improved the operational efficiency of total system.
The generalized information system of utilizing the GIS component development to come out is all inferior unlike traditional GIS software aspect big data of management and processing speed.Utilize spatial manipulation ability and abundant spatial analysis and query capabilities such as the existing function of GIS member can provide splicing fully, cuts out, superimposed, buffer zone.
The visualization system of data message of the present invention is applicable in the analytic system of a large amount of spatial datas and attribute data, particularly to the inquiry of system, analyzing responding time requirement than higher application.For example public security department relate to lot of data such as population, case, vehicle, and these data is nearly all relevant with geographical space, when running into that there is something special, requires again than reaction velocity faster, so technology of the present invention is very suitable.
Fig. 3 A-E has introduced the several examples of application of visible data information application system of the present invention.
