Roughness

The roughness data is required if you wish to calculate wind flow using WAsP within WindFarmer: Analyst.

Roughness is accepted in the WAsP .map format. You can prepare roughness .map files in WASP map editor or a GIS software.

You can import roughness in a .map file which is combined with elevations in either the roughness or elevations task. A .map file containing both elevations and roughness will be split after import and displayed as separate map layers. Note if you want to delete both roughness and elevation contours after importing a combined map you must delete the 2 layers separately.

Import a roughness file

Roughness data can be imported from a .map file.
