Description
Technical field
The invention belongs to police service Information System configuration technical field, it is related to three-dimensional geographic information platform, more particularly, to one
The three-dimensional police geographical information platform of kind and system architecture.
Background technology
The police geographical information platform of two dimension is more mature in the application of each public security department at present.Two-dimension GIS is substantially real
Showed with the relevant various functions of police business, such as：It is GIS map display function, map operation function, police map function, aobvious
Show GPS police cars function, map inquiry and positioning function, drawing function etc..Although public security department is met to a certain extent
Daily management mission needs, but two-dimension GIS is that three-dimensional spatial information is mapped as to the plane information of two dimension, is inevitably existed
It is excessively abstract in technique of expression, it is difficult to show the information such as humanity, environment, resource；Also lack telepresenc for user, be not inconsistent
Close the actual visual custom of people.Two-dimension GIS in terms of the intuitive that three-dimensional localization and information show there is limitation, by
This, comes into being for the construction demand of three-dimension GIS.
In recent years, security department and police unit are increasingly subject to weight to three-dimensional visualization abroad with virtual reality technology
Depending on the country has also carried out a few thing in this respect, realizes map operation, venue information locating query, security and police
The function of comprehensive displaying of the information of being engaged on electronic three-dimensional map, system is very fast in B/S Client browse maps, higher
Ground meets the actual combat demand of system.At present, the construction of police three-dimensional geographic information platform is still in the starting stage, is keeping magnanimity
Browsing for threedimensional model be smooth, on the Data Integration in existing public security two-dimentional system to three-dimensional scenic, existing two dimension is police
GIS-Geographic Information System be integrated into three-dimensional police geographical information platform and for specific transactions (strictly according to the facts current population's information inquiry,
Police service simulated flight etc.) the corresponding analysis and decision support module aspect of offer need further to develop and raising.
The original intention that digital city occurs just is intended in virtual digital world really express real world, and
Targetedly demand of specialty analysis and application are carried out thereon, play the core decision supporting capability of geographic information data.Therefore, number
The information of the target of word urban development, necessarily carrying objective world as much as possible, unlimited real simulation real world.So
And three-dimension GIS is developed so far, based on its application still is limited to browse with the visual presentation and roaming of city virtual scene.Study carefully
Its reason, is due to the limitation of conventional digital cybercity construction technology：Conventional digital cybercity construction, mainly using people
Work modeling, sample texture, the technological means of sampling textures, are the 3-d reproductions with the means realization of emulation to objective world,
Can not real simulation objective world；And each administrative department in the city such as public security, municipal administration, planning, gardens is it is desirable that can be truly anti-
Reflect " full information " city model of city present situation.
Be continuously improved to realize that Police Information strengthened research and integrated management are horizontal, improve security administration, police strength deployment,
The GIS-Geographic Information System construction and management of the public business such as security guard, people have carried out long-term exploration, it is proposed that various each
The solution of sample.For example, Chinese patent literature discloses a kind of digital police three-dimensional geographic information system based on cloud storage
[application number：201320055443.1], by portable terminal, road monitoring terminal, security protection monitoring terminal, wireless communication networks,
Retrieval server, geographic information server, police data server composition, portable terminal, road monitoring terminal, security protection monitoring

It is integrated.By monitoring distribution situation and real time execution situation of the various police work elements in space, its inner link is analyzed,
Reasonable disposition and scheduling resource, so as to improve the quick response and collaboration disposal ability of each police.
, still can not be from root although such scheme improves the performance of three-dimensional geographic information system to a certain extent
Previously described technical problem is solved on this.Particularly three-dimensional scenic is still mainly using artificial modeling, sample texture, sampling
The technological means such as textures, are to realize 3-d reproduction to objective world with the means of emulation, can not real simulation objective world.Base
City appearance simulation in the conventional digital urban construction pattern modeled by hand using sampling, can not really show objective generation
Boundary, while lack the expression of things in interior construction spacing and space with contacting.Due to the limitation of aeroplane photography, near-earth face
As missing so that outdoor scene three-dimensional is difficult to realize the model construction near the ground that becomes more meticulous, and can not meet the needs of observation application near the ground.
But conventional streetscape integrated technology near the ground, the mode of streetscape image frame is only switched to from two three-dimensional scenics, it is this
Streetscape image, its spatial relationships do not possess tight Fundamentals of Mathematics, can not be carried out with outdoor scene threedimensional model space accurate
Spatial match, also can not be with GIS data source slitless connection.
In addition, commanding elevation analysis is a great problem of guard's security work.In guard's security work, guard scene, police
Defend residence, the commanding elevation investigation on guard line periphery is always work problem.Traditional working mode is real to scene by people's police
The mode that ground makes an on-the-spot survey, investigates one by one carries out.People's police detect by an unaided eye, hand-kept, since the factors such as weather condition restrict, easily
Go wrong, and it is time-consuming and laborious.
On the other hand, with the continuous development of GIS, its application field is constantly widened, scope constantly expands, technology constantly rises
Level, the requirement to GIS is also higher and higher in practical applications by people, and new demand emerges in an endless stream.Meanwhile handle multi-source heterogeneous number
According to, operation is cross-platform etc. more and more the problem of in the development of GIS be also badly in need of solving.Data acquisition and renewal are to establish GIS
One significant investment of system, and it is then the important foundation that later system is established that data are carried out with rational classification and coding.From
Seen using angle, a successful generalized information system is largely dependent upon the synthesis of data and various modules with integrating.At present
Geographic information database generally uses the data model of Object-and Relation type, i.e., expresses geographical entity with Space Elements object；With
Attribute list expresses the feature of the spatial entities.Traditional code need to be using known atural object factor data to rely on, to discrete point-like number
It is a kind of definition space and the mode of known place name address date binding according to being encoded.Geographic information encoding technology is at present
Apply, still, encoded both for two-dimensional space, and can only be mapped known accurate in GIS-Geographic Information System construction extensively
Atural object.Traditional code, must be accurate because being tied to specific key element geographical entity, but in concrete operations, it is restricted
In data acquisition and the real-time and accuracy checked, it is difficult to accomplish to improve accurately, just can not for incomplete information data
Encoded.
