【摘要】：隨著GIS在地質(zhì)中的應(yīng)用,地質(zhì)GIS數(shù)據(jù)模型在幾何描述與表達方面日趨完善,但是對地質(zhì)構(gòu)造現(xiàn)象的語義描述與表達卻較為有限,制約了地質(zhì)研究者對地質(zhì)GIS地理解與應(yīng)用。為了增強地質(zhì)GIS數(shù)據(jù)模型中的語義信息,本文采用面向?qū)ο蟮姆椒?通過地質(zhì)對象來統(tǒng)一描述和表達地質(zhì)構(gòu)造現(xiàn)象的幾何與語義特征,設(shè)計了幾何與語義統(tǒng)一的區(qū)域地質(zhì)構(gòu)造GIS數(shù)據(jù)模型。本文設(shè)計了基于"詞匯概念-名詞解釋-幾何圖例"的地質(zhì)構(gòu)造現(xiàn)象的語義三角描述方法。依據(jù)區(qū)域地質(zhì)構(gòu)造的語義特征,采用線性分類法將區(qū)域地質(zhì)構(gòu)造現(xiàn)象劃分為3個大類、10個中類和33個小類,在此基礎(chǔ)上定義了地質(zhì)構(gòu)造現(xiàn)象的基本要素集和要素類,并基于地質(zhì)對象之間的幾何和語義關(guān)系,建立了區(qū)域地質(zhì)構(gòu)造現(xiàn)象要素的基本幾何網(wǎng)絡(luò)。采用ArcGIS Diagrammer Geodatabase建模工具,構(gòu)建了幾何與語義統(tǒng)一的地質(zhì)GIS數(shù)據(jù)模型。最后,以寧鎮(zhèn)山脈區(qū)域地質(zhì)構(gòu)造現(xiàn)象為例對該數(shù)據(jù)模型進行了試驗驗證,結(jié)果表明該模型具有較好的實用性。
[Abstract]:With the application of GIS in geology, geological GIS data model is becoming more and more perfect in geometric description and representation, but the semantic description and representation of geological structural phenomena is limited, which restricts geological researchers' understanding and application of geological GIS. In order to enhance the semantic information in the geological GIS data model, this paper uses the object-oriented method to describe and express the geometric and semantic features of geological structural phenomena through geological objects. The GIS data model of regional geological structure is designed with the unification of geometry and semantics. In this paper, a semantic triangular description method of geological structural phenomena based on "lexical concept-noun explanation-geometric legend" is designed. According to the semantic characteristics of regional geological structures, the regional geological structural phenomena are divided into 3 categories, 10 middle classes and 33 subclasses by linear classification. On this basis, the basic element sets and essential categories of geological structural phenomena are defined. Based on the geometric and semantic relations between geological objects, the basic geometric network of regional geological structural phenomena is established. The geological GIS data model with the unity of geometry and semantics is constructed by using ArcGIS Diagrammer Geodatabase modeling tool. Finally, taking the regional geological structure phenomenon of Ningzhen Mountains as an example, the data model is tested and verified, and the results show that the model has good practicability.
