Abstract:	近年來遙測影像逐漸成為地圖製作的素材之一，由於遙測影像多半在電腦上處理，同時背景極為複雜，因此得透過符號色彩與周圍影像背景呈現適度對比，方可達到傳統地圖上使用同一符號色彩的特性。本文透過雙重實驗，先以不同亮度的紅、橙、黃三色於遙測影像來執行觀光地圖的功能，繼而以具不同形狀特性的符號檢測色彩功能。結論發現，低亮度(L=80)的黃色為遙測影像上可讀性最佳的符號色彩，同時證明在遙測影像上形狀對色彩的影響並不顯著。 Imaged-based maps record variety of spatial information which can be treated as the role that traditional maps play. For the complex digital background, symbols' color design must be modified to keep traditional map's color characteristics, to achieve the best visual contrast around their surroundings, and to show the figured-ground phenomenon in the screen. Two experiments were involved in this study to check the tourist map function: First, selecting the best symbol color among red, orange and yellow lights. Second, examining color function with different symbol shapes. The conclusions reflect that symbols with yellow light (L=80) will generate the best legibility in the image-based maps, the result also approve that shape will not affect the color function significantly.
