地形圖上標高色彩之認知研究 A Perception of Hypsometric Colors Based Topographic Maps 高慶珍* Ching –Jen Kao 摘要 地形圖上標高色彩自來具有使用光譜色系的傳統，本研究乃依循前人的用色規則， 轉繪台灣北部二萬五千分一的地形圖到螢幕上，測試20 至30 歲間年輕人對標高色彩的 偏好，及透過色彩所估計的空間高度。從結果知道擁有三種非相連色彩的漸變色彩最受 喜愛，除可保有地形的連續性外，亦可達到視覺的可讀性，但要避免灰色調的加入。而 從色彩量化估計中，發現綠中帶黃易被估計為300 公尺左右，黃中帶綠則接近600 公尺， 黃中帶棕約可上估至 1000 公尺，而橙與棕色已被估計到 1000 公尺以上的地形了。從受 測者之背景分析也發現，唯有理論與實作雙管齊下，才能培育出優秀的地圖人才。 ABSTRACT Spectral color is the hue convention of hypsometric maps. According to earlier examples, this study transmit four sets of hypsometric color schemes in scale 1:25000 topographic map, to test the perception of young adult ranging from 20-30 years old. All questions are examined in computer. The results indicate that using hue transition will achieve the continuous terrain representation, but a successive hue sequential scheme and gray tone would be avoid to facilitate visual legibility. From the quantitative evaluation, greenish-yellow was evaluated about 300 meters. Reverse the situation the height was evaluated about 600 meters, while yellowish-brown was evaluated up to 1000 meters, and the color with brown or orange was evaluated above 1000 meters. These numbers offer a good reference once choosing color strategies. Besides, both of theory learning and practice is the best way to train a good cartographer. 關鍵字： 地形圖 標高色彩 Key words: topographic maps hypsometric colors *中國文化大學地理系講師 1 一、前言 遠在十六世紀之前，地形圖的繪製多半僅透過線條將山的外形勾勒出來，以表達各 山的相對遠近關係，直到十六世紀後達芬奇(Leonardo da Vinci)才首先將山脈的連續起伏 表達出來，但卻仍無法表達出山的高低位置。1667 年時，瑞士Hans Conrad Gyger 配合自 然色彩與三度空間概念，畫出第一幅真正的立體地形圖。但
