Aerial Images of Alaska's Arctic Coastal Plain; 1948, 1949

This dataset is comprised of 36 black and white 9x9 inch aerial images of four different study areas on Alaska's Arctic Coastal Plain taken between 1948-1949 and obtained from the Alaska Satellite Facility in 2013. The images represent an historical snapshot of the landscape from that time. The images were scanned and geo-referenced to various contemporary (2002-2010) satellite imagery using tie-point methods and splines for interpolation.本数据集包含1948至1949年间拍摄、覆盖阿拉斯加北极海岸平原4个不同研究区域的36张9×9英寸黑白航空影像，所有影像均于2013年从阿拉斯加卫星设施（Alaska Satellite Facility）获取，留存了彼时该区域地表景观的历史快照。 所有影像均经过扫描处理，并通过连接点法结合样条插值算法，与2002至2010年的多幅同期卫星影像完成地理配准。
