On the use of global DEMs in ecological modelling and the accuracy of new bare earth DEMs
Popis výsledku v původním jazyce
It is now widely acknowledged that the increasing availability of remotely sensed data facilitates ecological modelling. Digital elevation models are arguably one of the most common remote sensing products used in this context. Topographic indices derived from DEMs are widely used as surrogates for fieldmeasured environmental variables. Available global DEMs, such as those from the shuttle radar topography mission, however, do not provide information on bare earth elevation as they measure elevation of the highest objects above the ground. This affects the derived topographic indices and limits the use of global DEMs in ecological modelling. Unfortunately, most ecological studies ignore this limitation despite the fact that methods to remove the vegetation offset have been developed. We used high resolution LiDAR DTM to assess the accuracy of two newly available global bare earth DEMs where such methods were applied and to compare them with the SRTM DEM. Furthermore, we assessed the effect of DEMs ve
