TY - Data T1 - The orthophoto and DEM data set of the French Dr? Me River from 2005 to 2009 A1 - Kristell Michel A1 - Hervé Piégay DO - 10.12072/ncdc.nieer.db3168.2023 PY - 2020 DA - 2020-12-18 PB - National Cryosphere Desert Data Center AB - The research area of the data set is the 5km long river course between Luc en diois and reconbeau jansac in France and its surrounding geomorphic environment. The width of the river course is between 10-200M. The river bed is mainly composed of loose sandstone, gravel and pebbles. The river course is wide and shallow with small curvature. There is no dike along the river, the river course is not fixed and moves rapidly, and the vegetation on both sides of the river course is dense. The data set consists of two parts: one is orthophoto data, the other is DEM. There are ten GeoTIFF format data files in total. The geographic coordinate system is rgf93 ﹐ Lambert ﹐ 93. The orthophoto clearly shows the river and vegetation and other related landforms. The spatial resolution is 0.1M, and the pixel depth is 8-bit integer. The pixel depth of DEM compressed data is 32-bit floating-point type, and the spatial resolution is 0.2m/0.3m. The elevation of the whole area is between 480m and 580m. Taking the data of 2006 as an example, the orthophoto data is named as 2006dr ô me.tif, and the DEM data is named as 2006dr ô me dem.tif.
