Background technology
It is on the basis of former database that space-time database upgrades, geographical space variation targets information with reflection institute's survey region trend of the times situation (comprising landform, landforms, atural object etc.), revise, replenish and upgrade corresponding data in the former database, to reflect its present situation truly, the process that saves historical data, makes present database and real current situation to be consistent.
Spatial database upgrades that the discovery generally comprise change information is upgraded with extraction, master data base, three basic links of customer data base renewal and regular update, the fixedly renewal of intensity of variation, three kinds of basic models of incrementally updating.Incremental update is because its mode flexibly and can guarantee the trend of the times of spatial data best, is the main trend of future space database update.International Cartographic Association (ICA) and International Society for Photogrammetry and Remote (ISPRS) have set up " incremental update and spatial database versioned " joint working group specially in 1999 for this reason, have successively organized repeatedly symposium.
The discovery of change information at present and extracting mode comprise ground change metering system, with the superpose mode of relatively extracting variation targets information and of remote sensing image and vector data with the remote sensing image in the different moment three kinds of modes such as relatively extracting variation targets information that superpose.(1) adopt digitized mapping terminal system tie surface surveying instrument (as total powerstation, GPS etc.) to finish main at present aspect the change measurement of ground, the variation targets though it has only been resurveyed when change is measured, but what store in the Outcome Document of submitting to but is that all target datas (comprise and change and variation targets data not, be also referred to as snapshot), the variation targets information separated is not come out.When temporal data upgrades, again two different map snapshots are constantly superposeed comparison to extract variation targets information.In " On the automaticretrieval of updates in geographic databases based on geographic data matchingtools.ICA/ACI 1999-Proceedings/Acte[C] .Ottawa, Canada.1999.1291-13000 ", propose two different map snapshots are constantly superposeed comparison to extract the flow process and the method for variation targets information as Badard; Zhu Huaji change in time and space situation to the settlement place data of the comparison that superposes with the map snapshot in " the settlement place change in time and space sort research of extracting towards the increment information robotization (University Of Science and Technology Of Hunan's journal (natural science edition); 2006,21 (3): 65-68) " has been carried out exhaustive division.(2) in that being superposeed, remote sensing image and vector data relatively extract the variation targets message context, Zhang Jianqing etc. " based on the water system change-detection of remote sensing image and vector data (Wuhan University's journal (information science version), 2007:32 (8): 663-666) " introduced a kind of water system change information detection method based on remote sensing image and vector data.(3) in that being superposeed, difference remote sensing image constantly relatively extracts the variation targets message context, Zhang Jianqing etc. " based on the remote sensing image settlement place change-detection of LBP/C texture; (and Wuhan University's journal (information science version), 2008:33 (1): 7-11) " in a kind of remote sensing image settlement place change information detection method based on the LBP/C texture has been proposed; Alboody etc. have introduced a kind of extracting change information method of the GIS database update based on back classification and spatial reasoning etc. at " Post-classification and spatial reasoning:newapproach to change detection for updating GIS database (2008; 3rd InternationalConference on Information and Communication Technologies:from theory toapplications, 742-748) ".These methods all are to obtain the method for extraterrestrial target change information indirectly, owing to obtain the needs that link does not consider that space-time database upgrades in information, often do not collect information such as needed object variations time of spatiotemporal data update, change type, exist information content deficiency, distortion, the duplication of labour (extracting variation targets information again after the change measurement is the duplication of labour), reaction velocity to wait problem slowly.
Aspect spatiotemporal data update, document " Event-based incremental updating ofspatio-temporal database; Journal of Central South University of Technology (English Edition); 2004; 11 (2); 192-198 " at the robotization or the semi-automatic problem of dispersive target incremental update in the GIS database, has proposed a kind of incremental update method based on incident; This method is be the basis to close between geographic event, spatial entities change type and space-time database dynamic operation operator, determine the single entities change type by the geographical space change events, the robotization (or semi-automatic) upgraded to realize space-time database of the renewal operation of determining to adopt by the relation between single entities change type and the dynamic operation operator then.In " based on the Incremental Updating of topology linkage; mapping journal; 2008,37 (3): 322-329. ",, a kind of incremental update method based on topology linkage has been proposed at the renewal and the topological consistency maintenance problem of topological associated objects in the GIS database.It is at the different target type, and analytic induction goes out corresponding topology linkage type and segmentation type thereof; The different target development is inferred the rule of entity change type according to the topological relation between target before and after its semantic features, topological consistency constraint condition and the variation, and analyze or infer the situation of change of every kind of topology linkage type Central Plains associated objects and newborn target based on this, design and carry out the part interlock of corresponding renewal operation fulfillment database afterwards and upgrade and topological consistency maintenance; In " CADASTRAL DATA storehouse incremental update (2007.10, Beijing: Mapping Press) ", systematically analyze the segmentation of having set forth the land deeds pattern modifying type in the incremental update of CADASTRAL DATA storehouse and identification, change the back target automatic reconfiguration, upgrade and operate and problems such as topological consistency maintenance.Zhang Baogang is in that " (Beijing mapping; 2007 (1): the edition data of having analyzed the topographic database incrementally updating 1-4) is asked the sub-delta file summation of delta file method and map sheet generation delta file method to relief Map Database Updating with Incremental Mode, has proposed the scheme that production division carries out the topographic database incremental update.Liu Yong and Li Chengming are in " research of Updating method of urban fundamental spatial database method " (mapping science, 2006,31 (4): set forth 103-105) based on the spatial database tissue of ground state correction model and new technological process more.
Said method all is theoretically some situation of change, reason of changes and possible data organization method to be analyzed and discussed with upgrading treatment scheme, does not consider obtaining and problem such as docking calculation of change information.

Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Embodiment 1:
Enforcement of the present invention mainly comprises three contents: 1. change information collection and increment information file generate, and 2. 3. the data communication of change information collection terminal and master (client) database server leads (client) database incremental update.Set forth the embodiment of these three links below respectively.
1. change information collection and increment information file generate
Change information collection and increment information file systematic function are realized by the change information collection system.As shown in Figure 2, the change information collection system is installed on the portable intelligent terminal (as PDA, notebook computer, panel computer etc.), it comprises a spatial data acquisition module, can connect ground space information acquisition instruments such as GNSS, total powerstation, all-round instrument; The spatial data processing module; Increment information file generating module and a communication module.Its gordian technique is for classifying and at corresponding change information collection of dissimilar designs and method for organizing (being the increment information file layout) to the situation of change of geographical extraterrestrial target.
Anatomize the situation of change of the different spaces key element type in " geographical information element classification in GB/T 13923.-2006 basis and code " and " CH5002-94 People's Republic of China (PRC) Surveying and Mapping Industry standard " the land deeds specification of surveying and mapping " ", with reference to current domestic and international progress in this field.According to the application demand of the acquiring way of the variation characteristics of key element and variation targets and incremental update system reconfiguration variation targets state above-mentioned geographical space factor change is divided into three major types [classification of geographical space factor change and be identified as prior art]: the independent variation of (1) single entities (or claiming basic the variation), it can be artificial variation, also can be that nature changes, as locate the basis, water system, settlement place and affiliated facility, traffic, natural feature in vegetation and landforms and the soil property key element and anthropogenic landforms's etc. situation of change, the appearance in land deeds plot, disappear and change, pipeline newly-built, prolong, dwindle, discarded variation etc.; (2) topology linkage changes, as the interlock variation of pipeline, boundary and administrative division (comprising the land deeds key element); (3) derive from factor change, as the level line in the landforms, sea-bottom contour, elevation number point and the variation etc. of annotation point under water.
(1) the basic independent variation that refers generally to single landform, atural object key element that changes, take a broad view of the domestic and international research present situation, this class changes and can be subdivided into again 9 types (as shown in Figure 4): appearance, disappearance, attribute change, enlarge, dwindle, be out of shape, move, rotate and reappear.The variation of single such key element generally can not cause the variation of other key elements of periphery, and the locus that changes the back key element determines according to measurement data that fully the personnel that information such as its change type, transformation period, key element attribute are also reached the spot often are the clearest.Therefore its increment information file layout need write down information such as complete space, time, attribute, change type.
(2) to change be owing to the adjacency between target to topology linkage, topological relation such as be communicated with, comprise and cause.Comprise mainly that node between pipeline moves, transferring of administrative region (comprising the land deeds plot) adjust etc.Take a broad view of the domestic and international research achievement, topology linkage changes 5 kinds of basic conditions mainly comprising as shown in Figure 5, promptly node move, merge, cut apart, public boundary adjustment and compound branch and etc.
It often all is because people's activity causes that the above topology interlock changes, its transformation period, change type and relevant attribute information can both obtain indoor, have only the minority spatial positional information to obtain by field data collection, the position of mobile postjunction in moving as node, cut apart adjust with public boundary in the new border that forms etc.But its incremental update operation is very complicated, often relates to the continuous interaction of a plurality of targets, as moving of a node boundary mark, may affect the change of location, boundary line, spatial form and the area or even the topological relation in a plurality of plot.There are problems such as the target for the treatment of editing and updating is many, workload is big.If adopt the man-machine interactively mode to upgrade processing, in processes such as interpolation, deletion, modification, often be difficult to the various topology linkage problems between processing target effectively, be easy to generate omission, mistake, directly affect the quality of upgrading the back database.The change information collection that the present invention is directed to the topology linkage variation has designed simple and easy change information record format, promptly only write down the spatial positional information of the minority target that must obtain by field data collection for these change types, the full location of the target after interlock changes and attribute information then indoor according to the characteristics that change by system automatically (or semi-automatic) generate.The change type of simple target is then judged automatically by corresponding rule, and then the automatic or semi-automatic renewal of implementation space data.Concrete grammar is referring to " Chen Jun, Zhou Xiaoguang, 2008. Incremental Updating based on topology linkage, mapping journal, 37 (3): 322-329 ".
In 5 kinds of basic linkages shown in Figure 5 changed, merging did not need any spatial data of field acquisition; According to the characteristics of field data collection and storage, the plot is cut apart can be divided into that a plot is divided into two plot and a plot is divided into the two kinds of situations in a plurality of plot; Also can be divided into (1) again is adjusted into n+1 plot by a simple line with n plot to compound branch; (2) by a loop wire n plot is adjusted into n+1 plot; (3) other compound branches and three kinds of situations, as shown in Figure 6.(Topological Change is called for short TC) can be subdivided into 7 kinds of situations as shown in Figure 6 to need the topology linkage of field data acquisition spatial data to change like this.
(3) level line in " geographical information element classification in GB/T 13923.-2006 basis and code ", sea-bottom contour are for deriving from key element, they are not geospatial entities on the one hand, its locus often is not directly to measure on the other hand, but the discrete spot elevation data that obtain according to field survey, generate digital elevation model (or indoor), generate level line or sea-bottom contour according to digital elevation model then according to Aeronautics and Astronautics image generation digital elevation model.And elevation number point and annotation point itself neither spatial entities under water, but according to the needs selectivity annotation of interpretation map.Therefore its change information collection and incremental update method all are different from the basic variation and the topology linkage variation of single key element.In view of this, the present invention is directed to this situation and designed corresponding increment information record format, only write down the outer boundary of region of variation and the planimetric position and the elevation information of the inner a small amount of essential feature point of region of variation, generate the local digital elevation model then, and make up isocontour method.
According to above analysis to the space factor change, with " geospace data interchange format " (GB/T17798-1999, Geo-spatial data transfer format, be called for short CNSTDF) be the basis, designed corresponding increment information file layout, its recorded content comprises information such as spatial entities type coding, entity change type coding, change information collection time, transformation period, entity space and attribute.

3. lead (client) database incremental update
The principle of main (client) database update is identical, all be after communication module is received update request, automatically start (or by data base administrator's startup) refresh routine, update module is read in internal memory with the increment information file, and the corresponding data of determining to lead before respective regions changes in (client) database according to variation targets spatial dimension in the header file of increment information file reads in internal memory; Main (client) database update control module according to change type, time, space and the attribute information of the variation targets of increment information file logging to the corresponding data before changing adds, deletion and modification etc. should the zones after generating and changing trend of the times data, check consistance, and main (client) database of renewal makes it to save historical data when keeping the spatial data trend of the times.
Characteristics of the present invention are that main (client) database is a temporal database, and Data Update is not to replace legacy data (being that the snapshot formula is upgraded) with trend of the times data simply, and is based on the temporal data renewal of object version.The Spatio-Temporal Data Model for Spatial of main (client) database can be various, as ground state correction model, OO Spatio-Temporal Data Model for Spatial or object relationship type Spatio-Temporal Data Model for Spatial etc.
