摘要

高光譜影像可提供大面積區域近似連續分布之地表反射光譜資訊，極適合用於需探討地表地物反射光譜之細微變化的遙測工作，例如於精準農業之應用。國家實驗研究院儀器科技研究中心自製的高光譜影像儀適時提供了國內研發精準農業技術時所欠缺的影像資料，本研究以如何獲取中興大學位於台中縣外埔鄉之水稻精準農耕研究樣區產量、重要生育性狀，以及氮營養狀態的空間分布圖為例，說明高光譜影像儀在精準農業上之應用。

Hyperspectral imager provides nearly continuous reflectance spectrum of ground surface for large areas. This makes it particularly suitable for remote sensing studies to delineate minor changes in reflectance spectrum, such as applications in precision agriculture. The hyperspectral imager, ISIS, made by ITRC of NARL supplied the needed image data for researchers in Taiwan to develop the technologies for precision agriculture. In this study, the applications of hyperspectral imager on precision agriculture were illustrated by obtaining the spatial distribution of yield, important growth characteristics, and nitrogen status in a precision rice cultivation site, located in Taichung county, of NCHU.
