工作經歷


大學助教

加州聖地牙哥州立大學

八月 2013 - Present
Taipei, Taiwan

運用遙感探測、地理資訊系統及時空分析於學術研究:
一、為大數據之人口、社會經濟及遙測影像資料以視覺化及統計方式建立時空趨勢,並以此趨勢建立預測模型。
二、實驗機器學習於衛星影像以研究土地利用分類之可行性。
三、管理空間關聯式資料庫,包含PostgreSQL及ArcGIS geodatabase。
四、開發以時間序列Landsat衛星影像為主之自動偵測都市化演算法。
實驗課程教學:
一、教授遙測軟體及程式語言,包含ENVI、Erdas Imagine、TerrSet、eCognition、python和R。
二、指導及協助學生在遙測及空間分析相關計畫。
