  • polygon : n. 【幾】多邊形，多角形。 a regular polygon 正多邊形。adj. -lygonal 多邊多角形的（地面龜裂）。
  • attribute : vt. 1. 把（某事）歸因於…。2. 認為…系某人所為。n. 1. 屬性，特質。2. （人物、官職等的）標志，表徵。3. 【語法】屬性形容詞。
  1. 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。
  2. Based on the object - oriented technique, this study defines four types of geographical event, i. e. expansivity, contraction, rebirth and vanishment events for management of land use data. and it further designed an object - superposition data updating model based on the land use feature of point, line and polygon ， which would take the advantage of the gis overlay function to effectly implement of updating spatial and attribute data

    從面向對象的方法入手，定義了引起土地利用變化的擴展、收縮、新生與消亡四種地理事件，並分別按點狀地物、線狀地物和面狀圖斑的土地利用實體特徵設計了對象疊加更新模型，從而能利用gis強大的空間分析能力，來有效地實現空間數據和屬性數據的一致性更新。
