Using QGIS to create WAsP maps

posted on 2023-01-16, 07:38 authored by Rogier Ralph FloorsRogier Ralph Floors

Creating good roughness and elevation maps is important for microscale flow modelling for wind resource and siting assessment. The Wind Atlas Analysis and Application Program (WAsP) is often used for this purpose and requires maps as inputs. This repository contains tutorials for downloading elevation data (1a), making a hand-digitized roughness map (1b) and downloading a roughness map from the CORINE landcover using the QGIS software. The instructions for exercise 1a to 1c are given in the file "Creating a WAsP elevation and roughness map.pdf". 

Video solutions for exercises 1a to 1c are also available as .mp4 files.The repository also contains the scripts that can be installed as plugin in QGIS (wasp_scripts.zip). 

A tutorial for making landcover maps with a displacement height is given in "Creating a WAsP GML landcover map with displacement from CORINE data in QGIS.pdf". 


v1: first version

v2: some links were not working

v3: keep coordinate system when opening files in WAsP
