【摘要】:在地學(xué)領(lǐng)域中,通過地學(xué)模型模擬現(xiàn)實(shí)世界,應(yīng)用地學(xué)分析提供事務(wù)處理方案,用以解決現(xiàn)實(shí)問題,,已經(jīng)成為了地學(xué)研究中的一種常用方法。由于地學(xué)空間數(shù)據(jù)具有多源性、多領(lǐng)域、多尺度、數(shù)據(jù)量大、共享性強(qiáng)并且具有拓?fù)涮卣鞯忍攸c(diǎn),對(duì)地學(xué)空間數(shù)據(jù)進(jìn)行合理地存儲(chǔ)和管理,成為該方法的基礎(chǔ)。因此,對(duì)多源地學(xué)空間數(shù)據(jù)進(jìn)行存儲(chǔ)、管理和應(yīng)用的重要性就顯而易見。論文以遼寧省興城地區(qū)的地學(xué)情況為數(shù)據(jù)參考,對(duì)建立多源地學(xué)空間數(shù)據(jù)庫的相關(guān)理論和關(guān)鍵技術(shù)進(jìn)行了研究。 本文以遼寧省興城地區(qū)為研究區(qū),首先分析了研究區(qū)的地學(xué)情況,對(duì)地學(xué)空間數(shù)據(jù)及其特點(diǎn)進(jìn)行了總結(jié),對(duì)各種空間數(shù)據(jù)模型進(jìn)行了優(yōu)缺點(diǎn)的比較,重點(diǎn)對(duì)應(yīng)用Geodatabase空間數(shù)據(jù)模型和ArcSDE技術(shù)構(gòu)建多源地學(xué)空間數(shù)據(jù)庫管理系統(tǒng)進(jìn)行了分析,主要包括數(shù)據(jù)庫建立模式與系統(tǒng)框架構(gòu)成。該系統(tǒng)以Geodatabase空間數(shù)據(jù)模型為基礎(chǔ),利用SQL Sever作為數(shù)據(jù)庫平臺(tái),應(yīng)用ArcSDE空間數(shù)據(jù)引擎和GIS二次開發(fā)技術(shù),實(shí)現(xiàn)了多源地學(xué)空間數(shù)據(jù)的存儲(chǔ)、檢索、管理和輸出等功能。最后,以興城地區(qū)的地學(xué)空間數(shù)據(jù)為例,對(duì)多源空間數(shù)據(jù)庫管理系統(tǒng)的應(yīng)用進(jìn)行了簡(jiǎn)單的演示。 多源地學(xué)空間數(shù)據(jù)庫的建立對(duì)地學(xué)空間數(shù)據(jù)的集中存儲(chǔ)和統(tǒng)一管理進(jìn)行了嘗試,多源地學(xué)空間數(shù)據(jù)庫管理系統(tǒng)的實(shí)現(xiàn)對(duì)應(yīng)用地學(xué)數(shù)據(jù)研究現(xiàn)實(shí)問題提供了良好的平臺(tái),具有重要的現(xiàn)實(shí)意義和應(yīng)用價(jià)值。
[Abstract]:In the field of Geoscience, the real world is simulated by the geoscience model, and the application of geoscience analysis provides a transaction processing scheme to solve practical problems. It has become a common method in the study of Geosciences. The spatial data of Geosciences are stored and managed reasonably. Therefore, the importance of storing, managing and applying the spatial data of multi source geography is obvious. The paper takes the geoscience of Xingcheng area of Liaoning Province as the data reference, and carries out the related theories and key technologies for the establishment of a multi source Geoscience database. The study.
This paper, taking Xingcheng area of Liaoning Province as the research area, first analyzes the geoscience situation in the study area, summarizes the geoscience spatial data and its characteristics, compares the advantages and disadvantages of various spatial data models, and focuses on the construction of the multi source geoscience spatial database management system using the Geodatabase spatial data model and the ArcSDE technology. Based on Geodatabase spatial data model and SQL Sever as the database platform, the system uses the ArcSDE spatial data engine and the two development technology of GIS to realize the storage, retrieval, management and output functions of multi source spatial data. Finally, Xingcheng As an example, the application of multi-source spatial database management system is demonstrated.
The establishment of multi source geoscience spatial database has made an attempt at the centralized storage and unified management of geoscience spatial data. The realization of the multi source geoscience spatial database management system provides a good platform for the practical problems of Applied Geoscience data research, and has important practical significance and application value.
