Classification of subarctic woodland landscapes from historical and recent aerial photos to guide landscape management and ecological restoration

These datasets support the publication "Classification of subarctic woodland landscapes from historical and recent aerial photos to guide landscape management and ecological restoration". The raw data (aerial photos and Digital Elevation Model) are third-party materials from National Land Survey of Iceland (NLSI) and Loftmyndir ehf. OVERVIEW OF DATASETS - Woodland_increase2.csv -> Main dataset of woodland area increases, grazing protection (binary) and environmental parameters. - ..._NR.csv -> Individual Nightingale Rose diagram-datasets for each of the nine study areas - ..._masl-csv -> Individual elevational-datasets for each of the nine study areas - ..._slope.csv -> Individual slope-datasets for each of the nine study areas ABBREVIATIONS - BSS -> Bæjarstaðarskógur - HF -> Húsafell - LEY -> Leyningshólar - MF - Mjóifjörður - ND -> Neðri Dalur - OX -> Öxarfjörður - RS -> Ranaskógur - SD -> Steinadalur - TM -> Thórsmörk本数据集为论文《基于历史与近期航空影像的亚寒带林地景观分类以指导景观管理与生态修复》提供数据支撑。原始数据（航空影像与数字高程模型（Digital Elevation Model））均为第三方素材，来源为冰岛国家土地调查局（National Land Survey of Iceland, NLSI）与Loftmyndir ehf公司。 数据集概览 - Woodland_increase2.csv：涵盖林地面积增长、放牧保护（二分类）与环境参数的核心数据集。 - *_NR.csv：针对9个研究区域分别构建的夜莺玫瑰图（Nightingale Rose diagram）单数据集。 - *_masl.csv：针对9个研究区域分别构建的海拔单数据集。 - *_slope.csv：针对9个研究区域分别构建的坡度单数据集。 缩写说明 - BSS：Bæjarstaðarskógur - HF：Húsafell - LEY：Leyningshólar - MF：Mjóifjörður - ND：Neðri Dalur - OX：Öxarfjörður - RS：Ranaskógur - SD：Steinadalur - TM：Thórsmörk
