【摘要】：全月球撞擊坑數(shù)據(jù)是支撐月表形貌研究以及月球工程探測和科學研究的重要基礎性數(shù)據(jù),其全面性、精確性是衡量一個國家科技水平甚至綜合國力的重要指標�；阪隙鹨惶�、Clementine多光譜等探月數(shù)據(jù),智能化人工提取了全月球106030個直徑大于500 m的撞擊坑,在IAU公布的有名稱的撞擊坑及其描述形貌特征指標的基礎上,建立了描述全月球撞擊坑形貌特征的指標體系并獲得了所有撞擊坑指標的屬性值。針對現(xiàn)階段尚無一套完整的全月球撞擊坑數(shù)據(jù)庫的現(xiàn)狀,采用面向對象的Geodatabase數(shù)據(jù)模型組織全月球撞擊坑數(shù)據(jù),構建了包含位置、大小、形狀、坡度、方向、中央峰、輻射紋等7個大類52個小類指標的全關系型數(shù)據(jù)庫,其可對撞擊坑空間數(shù)據(jù)和屬性數(shù)據(jù)進行一體化管理,實現(xiàn)了對撞擊坑數(shù)據(jù)的存儲、檢索、處理和應用,為其他月球科學研究基于數(shù)據(jù)庫進行數(shù)據(jù)挖掘和應用提供了海量基礎數(shù)據(jù),為后續(xù)月球其他資源數(shù)據(jù)庫的構建提供借鑒。今后將進一步完善更新維護全月球數(shù)據(jù)庫的工作。
[Abstract]:The lunar crater data is an important basic data supporting the study of lunar surface topography and lunar engineering exploration and scientific research. Its comprehensiveness and accuracy is an important index to measure a country's scientific and technological level and even its comprehensive national strength. Based on the lunar exploration data of Chang'e 1 and Clementine, 106030 impact craters larger than 500m in diameter were extracted manually and intelligently. Based on the named impact craters published by IAU and their descriptive features, An index system describing the morphology of the lunar crater is established and the attribute values of all the craters are obtained. In view of the fact that there is no complete lunar impact crater database at present, an object oriented Geodatabase data model is used to organize the whole lunar impact crater data, and the position, size, shape, slope, direction and central peak are constructed. The whole relational database of 52 indexes in 7 categories, such as radiation stripes, can manage the spatial data and attribute data of impact crater, and realize the storage, retrieval, processing and application of impact crater data. It provides massive basic data for other lunar scientific research data mining and application based on database, and provides reference for the subsequent construction of other lunar resources database. In the future, the work of updating and maintaining the whole moon database will be further improved.
