Influence of artefacts in marine digital terrain models on habitat maps and species distribution models: a multiscale assessment

Remote sensing techniques are currently the main methods providing elevation data used to produce Digital Terrain Models ( DTM ). Terrain attributes ( e.g . slope, orientation, rugosity) derived from DTM s are commonly used as surrogates of species or habitat distribution in ecological studies. While DTM s’ errors are known to propagate to terrain attributes, their impact on ecological analyses is however rarely documented. This study assessed...
