DIGITAL ELEVATION MODEL CORRECTION IN URBAN AREAS USING EXTREME GRADIENT BOOSTING, LAND COVER AND TERRAIN PARAMETERS

The accuracy of digital elevation models (DEMs) in urban areas is click here influenced by numerous factors including land cover and terrain irregularities.Moreover, building artefacts in global DEMs cause artificial blocking of surface flow pathways.This compromises their quality and adequacy for hydrological and environmental modelling in urban l
