Above and close to built-up areas like cities, towns and villages, the results are less reliable. Close to and above forested areas, the results are also less reliable and should be interpreted and used accordingly. The data set was designed specifically for planning purposes and should be used with utmost care for design, development and detailed assessments of actual wind farms; where local, on-site meas-urements are strongly recommended.

The wind resource maps are subject to change without notice if and when more accurate and reliable data, models and procedures become available. Available documentation The wind atlas methodology is described in the European Wind Atlas (1989); the application of WAsP in the program documentation, see www.wasp.dk. The First Verified Numerical Wind Atlas for South Africa is a product of the Wind Atlas for South Africa project and is described further on the WASA download pages wasadata.csir.co.za/wasa1/WASAData Acknowledgements SANEDI (South African National Energy Development Institute) for managing WASA CSIR Environmental Management Services for providing height contour data for Eastern Cape and Northern Cape MetroGIS (Pty) Ltd. for providing height contour data for Western Cape in WAsP-compatible format.
