圖 1  研究系統架構  3.2 搜尋機制設計  搜尋機制可依前述分析之時間、空間、規格與 品質四類不同需求而設計,在表 1 歸納之所有項目 中,本研究依該項目是否滿足資料搜尋階段之需求 而區分為搜尋型項目與參考型項目兩類情形。搜尋 型項目包括如時間、空間與量化品質等,可依據系 統內建之知識,結合分析者參考影像之狀態而自動 形成搜尋條件;參考型項目則包括如影像處理歷程 等描述型項目,僅用於分析階段之參考。本研究所 設計之搜尋型項目包含: 1
圖 6  確認搜尋條件介面  圖 7  搜尋資料回傳介面  4.2 變遷分析介面  當分析者確認選取之資料後,系統即自動引入 參考影像與選取影像。並比較兩者之詮釋資料內容 (參考 3.3 節之規則) ,警示分析者資料可能帶有之 風險。本研究所發展之遙測影像變遷分析平台介面 如圖 8 所示,分析者可藉由同時比較不同時期之遙 測影像而判釋地物變遷之情況。其主要元件組成如 下:    工具列:工具列提供點、線、面三類數化工具, 分析者可開啟數化工具於任一地圖介面上數化, 所數化之成果將同步顯示於另一地圖介面。分
