Germany — Elbe/Dessau/Arneburg — Flood situation on 9/12 June 2013 — Change analysis — Overview — P39
收藏资源简介:
The flood situation along the Elbe remains tense. The map shows the change in the water surface of the Elbe in the Dessau/Arneburg area between 9 and 12 June 2013. The depicted water masks were taken from a TerraSAR-X scene from June 9th (recording time: 19:01 CET) and 12 June 2013 (recording date: 07:25 CET) derived. Both TerraSAR-X scenes have a spatial resolution of 8.25 meters. RapidEye data (recording date 2009) with a spatial resolution of 5 meters serve as a background image. A separate detail map (product no. 41) was created for the area of a dam break near Fischbeck. The strong increase in the southern area of the map shows the breakage of Klein Rosenburg on June 9, 2013. The levels shown in the map were recorded at the time of recording of the TerraSAR-X scene of 12 June. Please note that the flood situation in urban areas, under vegetation cover and in areas with high gradients may not be fully detected due to radar geometry. This product was created within the framework contract “ZKI-DE” between the Federal Ministry of the Interior (BMI) and the German Aerospace Center (DLR).

易北河沿岸的汛情依旧严峻。本地图展示了2013年6月9日至12日期间,德绍/阿尔讷堡区域内易北河水面的变化情况。本次展示的水面掩膜数据均由2013年6月9日与12日的TerraSAR-X影像(TerraSAR-X)提取得到,其中6月9日影像的成像时刻为中欧夏令时19:01,6月12日影像的成像时刻为中欧夏令时07:25。两幅TerraSAR-X影像的空间分辨率均为8.25米。空间分辨率为5米的2009年RapidEye卫星数据(RapidEye)作为本底影像。针对菲施贝克附近的溃坝区域,本数据集额外制作了一幅单独详图(产品编号:41)。地图南侧区域的水位显著上涨,对应2013年6月9日小罗森堡堤坝的溃决事件。地图中标注的水位数据,与2013年6月12日TerraSAR-X影像成像时的实测水位一致。需注意:受雷达成像几何特性影响,城市区域、植被覆盖区以及高坡度区域的洪水情况可能无法被完全识别。本产品基于德国联邦内政部(BMI)与德国航空航天中心(DLR)签订的框架合同“ZKI-DE”开发完成。最新版本的产品可通过http://www.zki.dlr.de获取。
