of almost all Earth has been sampled or scanned today so that DEMs are available at resolutions of 100 m or better at a global scale. Today, land surface parameters are successfully used for both stochastic and process-based modeling, the only remaining issue being the level of detail and vertical accuracy of the DEM.
