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。 -
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。 -

And hbds model is extended to hoom model. hoom is an objected - oriented integrated spatial model, which integrated geometric model, geographical feature model, geographical representation model, spatial calculation model and temporal model that based on hypergraph model. a normal object - oriented multi - resolution model is proposed to manage integrated multi - resolution spatial data that is dlg and dem data
這兩類空間數據的建模方法存在較大的差異，第一類數據的建模是通過特徵模型和超圖對象模型實現的，第二類數據的建模是通過對自適應規則三角形和不規則三角形的簡化與細化演算法的研究實現的。 -
