| 摘 要： | 多源矢量空间数据的评估方法一直以来比较欠缺。目前常用的专家决策方法,主要依赖专家的人工参与,不仅主观性强、执行效率低,而且使用门槛高。本文提出了多源矢量空间数据中面状水域的几何准确性与现势性评估方法,可以"量化"描述不同数据几何准确性与现势性的差异,并将评估结果可视化表达。试验结果表明,该方法科学客观、可靠有效。

| Abstract: | Evaluating methods for multi-source vector spatial data have been few and defective until now.Expert decision is a frequently-used method,but it relies on artificial participation,which means high-subjectivity and low-efficiency.And expert decision method is not convenient for common users.The paper puts forward an evaluating method for areal water of multi-source vector spatial data,which can evaluate geometric accuracy and currency quantitatively.And the visualization expression of evaluate result is intuitive and vivid for common users.The experiments indicate that this method holds higher scientificity,efficiency and reliability. |

| Keywords: | multi-source vector spatial data invariant moment geometric accuracy evaluating currency evaluating areal water, |
