Background technology
The mankind have two kinds of basic status: the one, in house; The 2nd, on the road of going to another house; On the way providing information service by Geographic Information System (GIS), is to provide indoor information service based on BIM (BIM) in indoor best solution of carrying out information service.Along with the development of human society, people utilize the mode of geography information passed by original map, paper map, electronic chart, Geographic Information System, space information system, stepping at present space time information systems times, the mankind never stop exploring the step of geospatial information application.Meanwhile, the mode of human living is from original cavern, building thatched cottage, brick wall watt room, until modern architecture, along with social development, the needed buildings such as people's life, work, amusement are to comfortable, green, environmental protection direction fast development.At present, result long-term by above-mentioned two aspects, that fast development brings is: (1) according to United Nations Population Fund's investigation, lives in cities and towns and urban district to the population that human society in 2008 exceedes half in history for the first time; (2), in densely populated area, U.S. Manhattan, the floor area of building of this area's buildings is considerably beyond the included land area in this area.More than describe and disclosed: classified or academic research development and the separate area of geographic information and the architecture construction field that form by science and technology, the development that need to comply with human society is merged, and this is the trend and direction of modern area of geographic information and the development of architecture construction field.Current present situation is in the fusion development in these two fields, lacks theoretical, method research, lacks engineering and supports.At present, in the time using geography information model and BIM, this two classes data message model self-organizing system, independent mutually.Along with technical development and demand pull, there is both forms in conjunction with application: the one, by adopting redirect between two systems, newly open the modes such as another system window and switch.This form has to adopt two kinds of engines or opens two systems and apply this two kinds of data, caused the increase of development time, cost of development.Meanwhile, two kinds of organic, closely bound up data of script are splitted into two stiff class data.The 2nd, realize the integrated application of the shallow hierarchy of geography information model and BIM by simplifying BIM.In the process of simplifying BIM, lost a large amount of building data messages, made to build data message and can not get correct and accurately use, its range of application and particle precision are also subject to great restriction.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the integrated association index Component of a kind of geography information model and BIM, realize the integrated application of geography information model and BIM, the technical scheme of employing is as follows:
A kind of geography information model and the integrated association index Component of BIM, it is characterized in that: comprise that geography information is obtained and processing module, dimensional topography creation module, matching addresses coding module, BIM obtains and processing module, BIM component classification molded tissue block, the geographical coordinate interrelation module of BIM, dynamic creation BIM member index module and quick-searching BIM construction part module, comprise the following steps: (1) geography information is obtained and processed: pass through remote sensing image, digital elevation model, topomap obtains geography information, (2) create dimensional topography: utilize remote sensing image, digital elevation model, topographic map data to create dimensional topography, (3) matching addresses coding: address information is loaded on dimensional topography, realizes matching addresses, (4) BIM obtains: import BIM, support the data file of all kinds of BIMs, (5) BIM Data Format Transform and classification: all kinds of BIMs are converted to privately owned form, and by the needs of application, reorganize classification, the member of BIM is classified by building, layer, room and vertical channel, and encode for each member has added the ID being made up of room and time attribute, (6) BIM and geographical coordinate interrelation: the incidence relation that creates BIM and geographic position, (7) adopt GIS method to choose BIM: to adopt the method for GIS to complete the space orientation of building, (8) index of dynamic creation BIM member: adopting the method quick-searching of GIS, navigating to after architectural object the index of this BIM member of dynamic creation, (9) quick-searching BIM member: support applications system quick-searching, the component information of inquiring about this BIM.
The principle of a kind of geography information model of the present invention and the integrated association index Component of BIM is as follows:
Take full advantage of the space attribute of geography information model, taking geography information model as carrier with reference system, under the support of address database, buildings in geography information model is carried out to geocoding, then set up buildings in geography information model and the spatial relationship of this building information model, spatial relationship completes space orientation and the data organization and management of BIM accordingly., the member of BIM is classified by building, layer, room and vertical channel, vertical channel is elevator, pipeline passway etc., and encodes for each member has added the ID being made up of room and time attribute meanwhile.In retrieval when this building, first create the unique index of whole members that this building comprises.Set up geography information model and BIM member has added close relation by this index.Having realized quick indexing in Geographic Information System, also can be by the counter geographical location information of finding self of building element to the member of BIM.For the seamless integrated data basis that provides of geography information and BIM.
On the basis that completes above work, to build the retrieval as object, adopt the method for Geographic Information System (GIS) to complete the space orientation of this building; To the retrieval of building element, adopting to build is the index of dynamic creation of object about this building element, has realized the integrated index building element of geography information model and BIM.
Its action relationships is described as follows:
The space orientation process of building in dimensional topography (GIS)
Obtain geography information: the geography information of obtaining comprises remote sensing image, digital elevation model, topomap etc.;
Create dimensional topography: utilize the data creation dimensional topographies such as remote sensing image, digital elevation model, topomap;
Matching addresses coding: address information is loaded on dimensional topography, realizes matching addresses.
After completing above step, can adopt the method for GIS to realize each buildings by address search, inquiry and location.
2, the processing procedure of BIM (BIM) member
Import BIM: the data file of supporting all kinds of BIMs;
BIM Data Format Transform and classification: all kinds of BIMs are converted to privately owned form, and by the needs of application, reorganize classification;
BIM is associated with geographic position: the incidence relation that creates BIM and geographic position.
3, geography information model and the integrated associated member index of BIM
The index of dynamic creation BIM member: adopting the method quick-searching of GIS, navigating to after architectural object the index of this BIM member of dynamic creation;
Support applications system quick-searching, the component information of inquiring about this BIM.
The advantage that the present invention has is as follows:
1, changed and used geography information model and BUILDINGS MODELS informational needs to open the present situation of two systems;
2, changed in the way that uses geography information model and BUILDINGS MODELS information can only lose architecture information;
3, in a system, realized the member of geography information model and the integrated index BIM of BIM.
