說明
這項圖像集提供熱帶地區的高解析度衛星監測資料，主要目的是減少和扭轉熱帶森林的損失，有助於對抗氣候變遷、保護生物多樣性、促進森林再生、復育和強化，以及推動永續發展，但所有用途都必須為非商業用途。
如要瞭解如何存取底圖，請按照這裡的註冊說明操作。
NICFI 衛星資料計畫的影像拼接圖 (又稱 Planet-NICFI 影像拼接圖) 包含每月和每半年生成的資料集，每 6 個月更新一次。馬賽克類型會儲存在圖片中繼資料欄位「cadence」中。使用該欄位以及每個影像集的開始和結束日期，找出所需圖像。
如要瞭解基本地圖的完整詳細資料，請參閱 NICFI 衛星資料計畫基本地圖規格。
如要進一步瞭解 NICFI (挪威國際氣候與森林倡議) 衛星資料計畫和提供的資料，請前往該計畫的網站。
為支持 NICFI 的使命，您可以將這項資料用於多個專案，包括但不限於：
- 推動全球熱帶森林的科學研究，以及熱帶森林提供的關鍵服務。
- 在熱帶森林開發國家/地區和管轄區，實施並改善永續森林管理和土地利用政策。
- 提高熱帶地區的透明度和問責制。
- 保護並改善熱帶森林國家/地區原住民和當地社群的權利。
- 創新解決方案，減輕全球商品和金融市場對森林造成的壓力。
