分類(Classification)
The process of sorting or arranging entities into groups or
categories; on a map, the process of representing members of a group
by the same symbol, usually defined in a legend.
資料內容利用定義之值域範圍將資料內容加以區分,同一種分類資料使用相同圖例 以利使用者判讀與使用
再分類(Reclassification)
The process of taking input cell values and replacing them with new
output cell values. Reclassification is often used to simplify or
change the interpretation of raster data by changing a single value to
a new value, or grouping ranges of values into single values—for
example, assigning a value of 1 to cells that have values of 1 to 50,
2 to cells that range from 51 to 100, and so on.、
重新考慮資料值域範圍 將原先完成定義之階層資料中重新利用定義之值域範圍加以重新分類或新增分類級距
聚合(Aggregation)
The process of collecting a set of similar, usually adjacent, polygons
(with their associated attributes) to form a single, larger entity.
處理資料內容相似的物件或相鄰的多邊形 將空間分佈與屬性資料內容加以合併行成單一物件或更大的實體
