The invention discloses a kind of Utilization of Geography Information System method of four dimensions, the method for designing of the UGIS of a kind of four dimensions based on information space.This method propose the concept of brand-new information space, and propose the concrete method how defining information space and how to embed the information space of fourth dimension in traditional three-dimensional geographic information system, thus the method being allowed to escalate into the GIS-Geographic Information System of future generation being four dimensions.
Description
Technical field:
Patent of the present invention relates to the method for designing of the GIS-Geographic Information System of a kind of four dimensions, especially a kind of empty with information
Between be the method for designing of GIS-Geographic Information System of fourth dimension degree.
Background technology:
GIS-Geographic Information System is a kind of specific highly important space information system.It is in computer hardware and software system
Under system is supported, the relevant geographic distribution data in earth top layer (including atmosphere) space all or in part is acquired, stores up
Deposit, manage, computing, the technological system analyzing, be shown and described.That geography information has narrow sense and broad sense point.The ground of narrow sense
Reason information has only included the entity information in the physical three-dimensional world, and the geography information of broad sense is except including in the physical three-dimensional world
Entity information outside further comprises the internal virtual information comprised of these entity informations.
The major technique that three-dimensional geographic information in early days uses is Digital Orthophoto Map, or is called for short again DOM.
DOM is digitized airphoto and the high resolution ratio satellite remote-sensing view data utilizing scanned process, and DOM enters by pixel
Row Geometric correction and inlaying, the digital orthoimage collection generated by certain figure amplitude range cutting.It is to have map geometry simultaneously
Precision and the image of image feature.Digital orthophoto map have precision height, abundant information, directly perceived true, obtain quick etc. excellent
Point, can control information as background, evaluate the precision of other data, actuality and integrity the most excellent；Can therefrom extract number
Various types of other magnanimity geography information, Natural resources information and socio-economic development information required for word city, existing for city
Generationization is built, is prevented and treated disaster and the offer reliable basis such as the various investigation of public physical construction planning and management；Also can therefrom extract
The information new with derivation, it is achieved the survey of repairing of map updates.The basic characteristics of DOM: compared with traditional symbolization line layout figure, DOM
Expressed information more horn of plenty, directly perceived, there is bigger development and application values.
By 2005 of this century, the Google of the U.S. started to release Google Earth on the basis of three-dimensional DOM
Service, Google Earth has been embedded in substantial amounts of relevant information service in traditional three-dimensional geographic information system service, has made traditional
GIS-Geographic Information System has been gradually evolved into a kind of more valuable for traveler, can not only inquire about geographical position physically
Put, and the comprehensive service of the business information relevant to geographical position or other relevant informations can be inquired about, as mileage
Upright stone tablet, geography information starts to break through three-dimensional pattern, develops to the four-dimension.
The GIS-Geographic Information System of space-time require to show GIS-Geographic Information System some in rather than surface
Information content.In UGIS, the information content that the urban geographic information of space-time is comprised is except three-dimensional
Avenue external physical characteristic information outside further comprises the internal information included on Mei Tiao street, mainly include trip
Trip information (tourist attractions information, travelling route information, cost information of travelling, service delivery in tourism business's information etc.), transport information
(public bus network information, circuit service time information, track cost information, circuit flag stop dot information, between any 2
Transfer information etc.), business information (business or the title of service, manage mainly scope, main characteristics commodity or service, contact method
With address etc.), and communal facility information etc..
Due to information can not individualism, information must exist in certain space, and this information rely exist sky
Between be exactly information space, but information relevant for substantial amounts of geographical position is being joined conventional three-dimensional by the Google of the U.S.
The when that DOM going, but do not propose how to define method and the definition of an information space quantitatively.Up to now, letter
Breath space is simply with a kind of field range simply determined with the size of display screen.Due to the display screen in comparable size
On, it is different that different resolution does the field range formed, and the most this fuzzy information space method for expressing cannot be helped
Help user its information interested to be accurately limited in a specific geographic range, thus bring three serious restrictions
The GIS-Geographic Information System of space-time application development problem in commercial kitchen area:
1. the problem of profit model.Geography information owing to being provided cannot be pin-pointed to certain specific region, and
Can only provide for scope with the whole screen that user is current, therefore cannot realize with the coverage of the geography information provided
Size determines that the standard of service charge is (such as by information contained amount in certain building, by contained on certain street quantitatively
Quantity of information, the quantity of information as contained by certain specific region, the quantity of information as contained by whole city charge respectively), but
Can only charge with the number of times used, thus these different value on different quantity of information of geography information cannot be embodied, simultaneously
Also between the user needing different quantity of information, the unfairness in charge is caused；
2. the problem cannot provided personalized service for application service provider.Application service provider generally requires basis
The application characteristic of oneself provides the user certain types of geographic information services, and such as in searching room service, application service carries
Wish to provide for potential house purchaser to examine on the spot service on the virtual net of target source of houses neighboring area for business, regarding including periphery
The distribution of frequencyization street scene, the business iconified and digitized public traffic information etc., in order to house purchaser need not go on the spot
Carry out prospecting and just the overall condition of target source of houses periphery can be had the understanding of individual experience type；The most such as in common line services,
Application service provider intentionally gets bus loading zone, and the station board of transfer stop particular location on certain section and periphery object of reference
Picture scene, in order to motroist can find station easily；The most such as in navigation Service, application service provider wishes
Hope the video scene of certain crossing or certain overhead road of city gateway, in order to motorist is identified；The most such as in local political affairs
In the digitalized city construction that mansion is leading, intelligent city's travel navigation public service platform of Tourism Bureau is desirable to provide whole city
The electronic digit Map Services of future generation of space-time.All these services all have obviously individual demand and (have
One region of needs in service, the service having only on a section having, the service needed only on a point having,
The service then needing whole city scope having), it is apparent that the geographical information platform based on cloud computing of current Google is not
It is provided that such personalized service；
3. on using, unfriendly cause traveler to feel to lack actually used value.Traveler is felt emerging when trip
Some specific geography information of certain specific geographic position periphery often of interest, but the ground provided at present due to Google of the U.S.
Reason information service can only provide the search in the visual field, therefore cannot accomplish to be accurately positioned and precise classification, and such as traveler needs
Knowing industrial and commercial bank's branch's information at certain geographic vicinity, he passes through to search in Google of U.S. geographic information service platform
What rope obtained would is that the substantial amounts of information about branch of industrial and commercial bank covering whole display screen, even includes that pawning house divides
The information of row, because bank and mortgage provisional capital include branch's two words in information key！Therefore traveler must pass through people
Work method finds oneself required information in this substantial amounts of information, and this is to traveler, particularly when traveler is on road
Often select to abandon the when of using such service by narrow and small mobile phone screen.And unfortunately pass through on road
One of mobile phones enquiring urban geographic information GIS-Geographic Information System exactly maximum application in commercial kitchen area！Additionally, for platform
For formula computer user, search is probably the geography information acquisition methods of most convenient, but for cellphone subscriber, may more need
Will be through precise classification, including the geography information of preset key word or search label to carry out quick retrieval and inquisition.
But, accurately define an information space and exist following difficult:
1. firstly, since for a city, the geography information in whole city will be stored in each information dispersedly
In space, in this sense for, a city is exactly the set of all of information space included in this city.Cause
This, information space actually should be much？It is again that the geographic information contents how coupling and just making city realizes between information space
Seamless fusion？All these problems the most do not solve.
2. secondly, the maximum value of the GIS-Geographic Information System in a city is embodied in its practical value for user.But
The different users requirement to the fineness of the particles of information space, the scope that the most namely spatial information is covered is big
Little being likely to different, the granulating problem the most how solving the information space in city does not the most solve.
3. last, the GIS-Geographic Information System in a city determines the separation of information space to the practical value of user can not
Can be linear, this is because the section length in the street in city is different, the section near each crossing be constituted
Geometry topology area is also random, and the habitual degree that the section in street user exactly is when using urban geographic information
Amount unit, such as we often can hear that people so describe the geographical position at a urban geographic information place: " XX shop
On A road, near B road ".The most also can be plus one: " just between B road and C road ".Therefore, how information space is solved
Nonlinear problem, particularly can be intelligently empty by information according to the different topology feature in the section associated by different crossings
Between be accurately defined in one centered by crossing, with a section as length, collectively form in this relevant section, crossing
In the region of one random geometry, and the problem being consequently formed the information space data directory of an intelligent nonlinear does not has
There is solution.
Summary of the invention:
In order to solve problem above, we have proposed the digitalized city method for designing of four dimensions based on information space.

Order is carried out.If there is irregular crossing situation, then arrange by following rule:
1) with a different tail arrangement rule.If a street starts with the cross street of the identical road name of two end, and
The cross street differing road name or only one end with two ends terminates, and centre is that only one of which is bigger in street
Section, second half then includes a plurality of less section, then section put in order from the beginning of a plurality of less section, with
Article one, bigger section is terminated；
2) different head arranges rule with tail.If a street differs the crossing street of road name or only one end with two ends
Road starts, and terminates with the cross street of the identical road name of two end, and centre is that only one of which is bigger in street
Section, second half then includes a plurality of less section, then section put in order from the beginning of a bigger section, then
Carry out in order by the same sequence direction in bigger section then including a plurality of less section from second half.
3) rule is arranged with head with tail.If a street starts with the cross street of the identical road name of two end, with
Article one, the cross street of the road name that two ends are identical terminates, and centre is the section that only one of which is bigger in street, and another
Half then includes a plurality of less section, then putting in order of section can be from bigger road by from the beginning of equidirectional, it is also possible to
From less section by equidirectional in order from the beginning of.
4) different different tail arrangement rule.If intersecting of the road name that a street differs with two ends or only one end
Street starts, and the cross street of the road name that differs with two ends or only one end terminates, then by intersection leg occur suitable
Successively carrying out occurs in sequence.
4. association section judging rules
1) rule 1 that section is relevant is judged.In a street, after an intersecting therewith street name occurs for the first time
In the middle of before again occurring to second time, other sections all of are all the associations in the section occurring cross street name containing second time
Section；
2) rule 2 that section is relevant is judged.In a street, in one article of intersecting therewith next adjacent street name
In the middle of before again occurring to second time after once occurring, other sections all of are all that the next one occurred containing second time is adjacent
The association section in section of cross street name；
3) rule 3 that section is relevant is judged.In a street, two adjacent sections but the two end roads in crossing street
Two sections that the two end road names in the street intersected that name differs or the next one is adjacent differ are the sections that is associated；
4) rule 4 that section is relevant is judged.At the parting of the ways, every meet that to connect the section of head-to-tail rule be all association road
Section；
5. target information search rule.Every target information associating in section with target geographic position that occurs in is equal to
