The digital roughness models in WindPRO are mainly based on land-cover maps from based on open internet resources. The setup in windPRO provides an estimate of the roughness lengths or roughness classes based on remote sensing sources or land use databases. The roughness length is typically found from a lookup table (LUT) that translates a land-cover classification into a roughness length.
A Word Of Caution
Note, that these sources - when considering wind energy applications - are typically not sufficient for a detailed and accurate roughness classification of a site. However, they may prove helpful for an initial analysis and as support for a more detailed analysis. Especially, the roughness levels assigned to the digitized areas need to be verified and normally needs adjustments by the user.
