Abstract:	全球氣候暖化為當代地球科學研究之核心焦點，其中冰河退縮不僅是氣候變遷的顯著指標，更提供了探究地表動態演化的關鍵線索。本研究聚焦於北極斯瓦巴群島（Svalbard）之 Waldemar 冰河，旨在探討其退縮後新生裸露地標之地貌特徵。 Kaffiøyra 地區地質構造複雜，地層橫跨前寒武紀基盤至第三紀，並保有顯著的斷層活動遺跡，具備極高之科學研究價值。早期極區地圖多仰賴中低解析度衛星遙測，缺乏高精確度之空間資訊，且受限於大面積冰川覆蓋，歷史地形資料極為匱乏。本研究之創新與優勢在於導入無人飛行機（UAV）攝影測量技術，針對冰河退縮區進行高解析度影像採集，並透過 Agisoft Metashape 產製公分級解析度之數值地形模型（DEM）與正射影像（Orthophoto）。此高精度資料不僅能優化水文分析模型與地質詮釋，更精確建構了 2023 年 Waldemar 冰河區域之地貌現狀。本研究成果填補了台灣在極地地形測繪資料之空白，為後續冰川學與環境變遷研究提供關鍵的基礎數據庫。;Global warming has become a focal point of earth science research, and glacial retreat is one of the critical indicators of climate change. The study focuses on the post-glacial landforms of the Waldemar Glacier in Svalbard. The Kaffiøyra region of western Svalbard features a complex geological structure, spanning from Precambrian basement rocks to Tertiary formations, and evidence of tectonic faulting. Despite the scientific significance of the area, existing polar cartography often suffers from low resolution or a lack of historical data due to the extensive prior large-scale glacial coverage. To address these limitations, this research used Unmanned Aerial Vehicle (UAV) photogrammetry to survey newly exposed terrain. The research generated centimeter-scale digital elevation models (DEMs) and orthomosaics by processing aerial imagery through Agisoft Metashape. These high-resolution data can be used in precise hydrological analysis and geomorphological interpretation of the Waldemar Glacier topography in 2023. This study contributes foundational high-resolution data to Taiwan’s polar research initiatives, establishing a rigorous geographic baseline for future longitudinal studies in the Arctic.
