    煤礦床為一分佈於三維地理空間的地質實體，所以礦山生產的一切過程都與三維空間有關，從資源勘探到礦井生產的主要圖紙和技術數據都是為了確定煤礦床的正確位置和相應的參數。
  2. Originated from geographic information technique, spatial decision supporting technique can offer corresponding spatial knowledge and decision supporting for information management, process control and scientific research, etc. this thesis addresses itself to the basic conception and development of the current spatial decision supporting technique, analyzing the characteristics of spatial data and spatial entity and spatial decision supporting and discussing the realizing methods of spatial decision supporting

    源於地理信息系統的空間決策支持技術，可以為信息管理、過程式控制制、科學研究等提供相應的空間知識與決策支持。本文首先對當前空間決策支持技術的基本概念和進展作了論述，對空間數據、空間實體、空間決策支持的特點進行了分析，討論了空間決策支持的實現方法。
  3. Research result shows that the object - oriented geographic spatial model has stronger representative ability, is easier understood and accepted ; using the concept of geometric data type unify the process method of attribute and spatial data, and simplify entity query and analyses. the topologic relations between entities, which are not been stored in explicit formulation in the model, can be achieved through collective operation of geometric object ' s hypergraph model. compared with traditional his, the query and analyses ability of which based on new model are stronger

    研究結果表明，面向對象的地理空間模型具有更強的表現能力，並且容易被理解和接受；採用幾何數據類型的概念，可以使對非空間數據和空間數據的處理方法相統一，而且會使對實體的各種屬性數據（包括空間屬性）的查詢和分析模型更加簡單；對于面向對象模型中不顯式表示的地理實體間的空間拓撲關系，可以利用實體的幾何對象的超圖模型間的集合運算來求得；基於面向對象地理空間模型的實體查詢和分析，也比基於傳統gis數據庫查詢和分析具有強得多的功能。
  4. As far as model is concerned, the forth generation software should be characterized with spatial entity - oriented. the paper established the geographic spatial model based on the thinking of object - oriented ; studied the structure of the model " s elementary unit - - geographic entity ; brought forward the concept of geometric data type which characterize entity ' s spatial feature in the structure ; defined five kinds of geometric data types such as point, arc, area, composite arc, composite area ; and formalized their collective operation using hypergraph. at the end of this paper writer studied preliminarily the method of entity query and analysis based on the model

    本論文從面向對象的基本思想出發，建立了面向對象的地理空間模型；研究了地理空間模型中的基本單位? ?地理實體的結構，針對實體結構中用來表徵實體空間特性的組成部分? ?幾何對象，提出了其取值范圍，即幾何數據類型的概念；對點、弧、面、復合弧和組合面五種幾何數據類型進行了定義；並使用超圖工具對幾何數據類型的集合操作進行了形式化描述；對基於面向對象的地理空間模型的實體查詢和分析方法也做了初步研究。
  5. The inland part of a political or geographic entity

    內陸一個政治或地理實體的內陸部分
  6. In fact the problem of traditional gis software lies in its model, which is dedicated to how to abstract, represent process, analyses and apply geographic entity data and the relations between them in a system

    傳統gis所存在的主要問題歸根結底還在於地理信息系統軟體模型的問題，即在系統中如何對地理實體及其關系進行抽象、表達、處理、分析和應用的問題。
  7. Virtual reality in digital city strengthened the interaction with user, made the relation closer between geographic entity ' s spatial and non - spatial property. it has great theory and practice significance in digital city ' s research

    數字城市中的虛擬導航增強了與用戶的交互性，使地理實體的空間與非空間屬性特徵緊密結合，實現了三維場景與空間數據庫的交互和空間查詢，在數字城市的研究工作中有一定的理論意義和實用前景。
