GIS is the infosystem that is specifically designed to collection, storage, management, analysis and expression of space data, and it is expression, the world, simulating reality space and the instrument that carries out the spatial data Treatment Analysis, also is a science and technology of analyzing about Spatial information processing.With regard to the tool characteristics of GIS, it adopts digital form to represent for people and analyzes the function that the realistic space world provides a series of spatial operations and analysis, comprises synthetically storage administration people research and solves the required various spatial datas of space problem; According to user's the relevant space distribution information of requirement inquiry, carry out various statistics and calculate, tabulate and chart; Needs according to planning, management, production carry out the simulative optimization of multifactorial synthetic study, decision scheme etc.
In GIS, real world is expressed as a series of geographic element and geographical phenomenon, and these geographic entitys are at least by locus reference information and two ingredients of non-positional information.Abstraction process to real world objects it has been generally acknowledged that 9 levels, connects by 8 interfaces between these nine levels, has defined the transformation model in the set world from the real world to the geographic element.These 9 levels are followed successively by real world (Real World), the concept world (Conceptual World), the geographical space world (Geospatial World), the yardstick world (Dimensional World), the project world (Project World), the some world (Points World), the solid world (Geometry World), the geographic element world (Feature World) and the elements combination world (Feature Collection World).8 interfaces that connect these nine levels are respectively understanding (Epistemic) interface, GIS subject (GIS Discipline) interface, local metric (Local Metric) interface, information community (Community) interface, space reference system (Spatial Reference) interface, solid structure interface, element structure interface and project structure interface.Wherein the first five model is abstract to real world, is not implemented in computer software; Rear four models are mathematics and models symbolism about real world, will be implemented in software.
Building entity in the expressed real world of wisdom building object-oriented data model is that the overall model of wisdom building as shown in Figure 2 through the abstract essentiality content of model.
The wisdom building object-oriented data model of concrete foundation mainly comprises the content of three aspects: as shown in Figure 3:
(1), space geometry information
Be geometric coordinate set, the locus of each object in the sign building, such as longitude and latitude, planimetric rectangular coordinates and coordinate etc., its geometric figure shows as an object, line object and in the face of the three types such as resembling.
1.1 some object
Point is that specific position is arranged, and dimension is zero object, comprising:
. some entity (Point Entity): be used for representing an entity;
. annotation point: be used for the location annotation;
. interior point (Label Point): be used for recording polygonal attribute, be present in the polygon;
. node (node) (Node): the expression line terminal point and starting point;
. angle point (Vertex): the internal point of expression line segment and segmental arc.
1.2 line object
Line object is that dimension very commonly used in the object-oriented data model of wisdom building is 1 space component, and the space attribute on indicated object and their borders is represented that by a series of coordinates wherein, the geometric attribute of line object comprises:
. length: from the overall length of origin-to-destination;
. flexibility: be used for expression as the degree of the bending of building roof;
. direction: the water (flow) direction that is used for the expression water supply line.
The geometry entity of line object comprises line segment, border, chain, segmental arc, network etc.
1.3 in the face of resembling
In the face of dimension in the OO mathematical model that likes the wisdom building is 2 space component.
Planar entity is the description to class phenomenons such as body of wall, floors.Usually adding interior point by a closed curve in database represents.Planar entity has following spatial character (geometric attribute of facing elephant comprises):
. area;
. girth;
. shape;
. independence or with other atural object adjacency, such as body of wall and peripheral floor or roof;
. plyability and non-overlapping, the juxtaposition phenomenon all might appear such as the illumination zone of light on the roof, the ventilation scope of air-conditioning system etc., and each parking stall in parking lot is adjacent but can not occur overlapping in general.
(2), entity space relation
The entity space relation generally includes: metric relation, and far and near such as the distance between two objects; Position relation has defined the orientation between two objects; Topological relation has defined the relations such as connection, adjacency between the object.
2.1 metric relation
Fundamental space object metric relation comprises a little/distance between the point, point/line, point/face, line/line, line/face, face/face.Can finish the parameters such as angle such as body of wall and approaching object, tendency, orientation, area, volume, lighting radiation degree, the sensible property in path according to these fundamental relations.On the basis of this external fundamental space object Relations Among, can construct the metric relation between point group, line-group, the face group.For example, on the basis of known point/line topological relation and a point/metric relation, can obtain a little/between shortest path, optimal path, service range etc.; Known point, line, surface metric relation is carried out distance measurements calculation, contiguous analysis, cluster analysis, buffer zone analysis, Thiessen polygon analysis etc.
2.2 position relation
Position relation, it has defined the orientation between the object, has just described position relation such as " elevator in northwest of office to ".For the position relation between the objective definition, the relation between the defining point target at first.Given position reference, i.e. orthogonal X, Y coordinate axis, it is reference that the straight line perpendicular to coordinate axis is adopted in the definition of direction relations.Make that Pi is the point (P is former target) of target P, Qj is the point (Q is reference target) of target Q, X, the Y coordinate of X (Pi) and Y (Pi) function reentry point Pi.Then P and Q have following 8 kinds and may concern in two-dimensional space, and provide a complete relation to cover.These contextual definitions are:
Restricted_East(Pi，Qj)=X(Pi)＞X(Qj)And?Y(Pi)=Y(Qj)
Restricted_South(Pi，Qj)=X(Pi)=X(Qj)And?Y(Pi)＜Y(Qj)
Restricted_West(Pi，Qj)=X(Pi)＜X(Qj)And?Y(Pi)=Y(Qj)
Restricted_North(Pi，Qj)=X(Pi)=X(Qj)And?Y(Pi)＞Y(Qj)
North_West(Pi，Qj)=X(Pi)＜X(Qj)And?Y(Pi)＞Y(Qj)
North_East(Pi，Qj)=X(Pi)＞X(Qj)And?Y(Pi)＞Y(Qj)
South_West(Pi，Qj)=X(Pi)＜X(Qj)And?Y(Pi)＜Y(Qj)
South_East(Pi，Qj)=X(Pi)＞X(Qj)And?Y(Pi)＜Y(Qj)
More than 8 kinds of relations can accurately judge by the projection of point.If any any two points, above-mentioned 8 kinds of relations must have a kind of satisfied.And these relations have transitivity, and the other relation can mutually be changed and (such as North_East (PI, QJ) South_West (QI, PJ), by above-mentioned 8 kinds of relations are expanded, can draw other 4 kinds of direction relationses, that is:
East(Pi，Qj)=North_East(Pi，Qj)Or?Restricted_East(Pi，Qj)Or?South_East(Pi，Qj)
South(Pi，Qj)=South_West(Pi，Qj)Or?Restricted_South(Pi，Qj)OrSouth_East(Pi，Qj)
West(Pi，Qj)=North_West(Pi，Qj)Or?Restricted_West(Pi，Qj)Or?South_West(Pi，Qj)
North(Pi，Qj)＝North_West(Pi，Qj)Or?Restricted_North(Pi，Qj)OrNorth_East(Pi，Qj)
Take the direction relations between the point target as the basis, the direction relations between all the other targets can similarly define.

| B(A)∩B(B) | B(A)∩I(B) | B(A)∩E(B) |
| I(A)∩B(B) | I(A)∩I(B) | I(A)∩E(B) |
| E(A)∩B(B) | E(A)∩I(B) | E(A)∩E(B) |
Table 1
For each element in this matrix, " sky " and " non-NULL " two kinds of values are arranged, 9 elements can produce 512 kinds of situations altogether.
