Classified channel masks of portions of 13 rivers across the Arctic and areas of floodplain erosion and accretion ranging from 1973 to 2016

This dataset provides classified river channel masks of 14 reaches of 13 Arctic rivers, as well as masks showing areas of erosion and accretion along the rivers of specified time periods. These rivers include the: Colville River, Alaska; Indigirka River, Russia; Kolyma River, Russia; Koyukuk River, Alaska; Lena River, Alaska; Noatak River, Alaska; Ob River, Russia; Pechora River, Russia; Selawik River, Alaska; Taz River, Russia; Yana River, Russia; Yenisei River, Russia;, and the Yukon River, Alaska. The dataset was generated from a total of 114 images including landsat, higher resolution satellite imagery, and aerial photography over time periods ranging from the 1970s and 2016. A full list of the image dates, row and path (for Landsat), and pixel resolutions is provided in the dataset. These masks provide the source data for the erosion, accretion, and planform measurement provided in the companion dataset: doi:10.15485/1571527.

本数据集提供了13条北极河流共计14个河段的分类河道掩码（mask），同时包含各指定时间段内沿河流分布的侵蚀区域与淤积区域掩码。所覆盖的河流包括：阿拉斯加的科尔维尔河、科尤库克河、勒拿河、诺阿塔克河、塞拉威克河、育空河；俄罗斯的因迪吉尔卡河、科雷马河、鄂毕河、伯朝拉河、塔兹河、亚纳河、叶尼塞河。本数据集由总计114幅影像生成，数据来源涵盖陆地卫星（Landsat）、更高分辨率卫星影像以及航空摄影，时间跨度覆盖1970年代至2016年。数据集内提供了所有影像的拍摄日期、（陆地卫星的）轨道行号与路径号以及像素分辨率的完整清单。上述掩码可为配套数据集doi:10.15485/1571527中提供的侵蚀、淤积及河道平面形态测量任务提供源数据。
