资源简介:
This dataset provides four sets of geotiffs used for the mapping and analysis an alluvial floodplain reach of the East River, downstream of Gothic, CO, U.S.A near Crested Butte. The files include binary masks of the river channel at five in intervals from 1955 to 2015. Another set of rasters provide a map of the channel centerline pixels of the river for each date. Also included in the dataset are rasters of the areas of channel change due to migration over 8 time intervals. The masks were generated from aerial and satellite imagery collected on seven dates over a sixty-year timespan: 1955, 1973, 1983, 1990, 2001, 2011, and 2015. The masks were analyzed using the Spatially Continuous Riverbank Erosion and Accretion Measurements (SCREAM) software detailed in Rowland et al. 2016 to create the channel centerlines and the change area rasters. The change masks were generated for the following time periods: 1955-1973; 1955-2015; 1973-1983; 1983-1990; 1990-2001; 2001-2011; 2001-2015; and 2011-2015.
本数据集提供四组地理栅格(GeoTIFF)数据,用于美国科罗拉多州哥特镇下游、靠近克雷斯特德比特的东河冲积平原河段的制图与分析。该数据集包含1955年至2015年五个时间区间内的河道二进制掩膜文件。另一组栅格数据为各对应日期的河道中心线像素分布图。数据集还涵盖了8个时间区间内因河道迁移产生的河道变化区域栅格数据。
上述掩膜数据基于60年时间跨度内7个日期的航空与卫星影像生成,分别为1955年、1973年、1983年、1990年、2001年、2011年及2015年。研究人员采用Rowland等人2016年发表的空间连续河岸侵蚀与淤积测量(Spatially Continuous Riverbank Erosion and Accretion Measurements, SCREAM)软件对掩膜数据进行分析,以生成河道中心线及河道变化区域栅格。
河道变化掩膜针对以下时间段生成:1955-1973年、1955-2015年、1973-1983年、1983-1990年、1990-2001年、2001-2011年、2001-2015年及2011-2015年。
