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.本数据集由36张9×9英寸的黑白航空影像组成，涵盖阿拉斯加北极沿海平原的四个不同研究区域，影像拍摄于1948年至1949年间，并于2013年从阿拉斯加卫星设施（Alaska Satellite Facility）获取。这些影像留存了该时段地表景观的历史快照。 所有影像均经扫描处理，并通过连接点匹配法结合样条插值法完成与多幅2002年至2010年同期卫星影像的地理配准。
