As wind energy analysts, we often find ourselves using land-cover datasets as the starting point of making our roughness classification models.
Until now, the spatial resolution of the global land cover datasets has been limited to about 300m. This obviously limits the accuracy at roughness shifts (such as edges of forests, coastlines or cities).With the release of the “Copernicus Global Land Service – Land Cover 100m” a high-resolution 100m dataset with global coverage is available directly in windPRO.
