【摘要】:隨著空間數(shù)據(jù)獲取手段的進(jìn)步和數(shù)據(jù)質(zhì)量研究的深化,考慮用戶需求、輔助數(shù)據(jù)使用決策的空間數(shù)據(jù)可用性評(píng)估研究開始受到關(guān)注。在闡述空間數(shù)據(jù)可用性概念和介紹代表性研究方法的基礎(chǔ)上,考慮不同的因素對(duì)現(xiàn)有方法進(jìn)行了比較分析。針對(duì)現(xiàn)有方法的缺陷,設(shè)計(jì)了多源空間矢量數(shù)據(jù)可用性評(píng)估的方法,并闡述了其中的關(guān)鍵環(huán)節(jié)和解決方案。
[Abstract]:With the advancement of spatial data acquisition means and the deepening of data quality research, taking into account the needs of users, The research on spatial data availability evaluation, which is used to aid data use decision, has attracted much attention. Based on expounding the concept of spatial data availability and introducing the representative research methods, Considering different factors, the existing methods are compared and analyzed. According to the shortcomings of the existing methods, a method for evaluating the availability of multi-source space vector data is designed, and the key links and solutions are described.
