多邊形屬性表-
Results showed that, attribute data obtained by this way avoided deficiency of polygon overlap way, as a result, the logistical consistency between map data and attribute data reached over 90 % on average. database pivot precision was 0. 18mm, data quantity during manipulation was decreased greatly, data treatment was more convenient, computation velocity was boosted greatly. workload of map and table pretreatment and edition was mitigated on large scale, spatial data precision was increase
研究表明:用該方法獲得的屬性數據,避免了多邊形疊加方法的不足之處,能使圖形數據和屬性數據邏輯一致性平均達到90以上,數據庫點位精度達到0 . 18mm ,且操作中圖層數據量大大減小,數據處理更為方便,運算速度大為提高;減輕了圖表預處理和編輯的工作量,使空間數據精度提高。
