CEMS-Flood land surface data are all the maps required by the spatially distributed hydrological model LISFLOOD. They include information on the topograhy and the rivers (e.g. Digital Elevation Model, drainage network, location of lakes and reservoirs, channel width etc..) and on the land (typical on soil and vegetation). These maps are generally referred to as "static maps" and generated from European and global databases. A detailed description of LISFLOOD static maps for CEMS-Flood system and how they were derived can be found in https://ec-jrc.github.io/lisflood-model/4_1_annex_input-files/ and Choulga et al. (in prep).
