Introduction

To use satellite-based data in the wind-energy flow modelling chains and to integrate those data into wind-energy yield assessments. That was one of the goal of the InnoWind project that took place during years 2017-2020 and where EMD International A/S formed a project partnership with the Technical University of Denmark, DHI-GRAS, Vestas and Vattenfall, see more at www.innowind.dk. The project was finalized in spring 2020 with a lot of fast-track data-products derived from satellite and remote sensing missions being available directly in windPRO, see our dedicated InnoWind wiki page. During the project, DHI-GRAS has developed its DHI-GRAS InnoWind Premium Data Service. This service allows DHI-GRAS to deliver data-layers of forest-height, land-cover and leaf-area-index in 20m resolution – based on Sentinel 1 and Sentinel 2 source data - with data layers being derived using machine-learning algorithms. These data are easily read with windPRO – as they are typically delivered in geotiff-format. Users that is interested in this products may contact DHI-GRAS for further details and pricing, see www.dhi-gras.com.

Premium Data Samples and windPRO legends

Two sample packages of premium sample data are available for download for WAsP and windPRO users: one is for the area around the DTU Risø campus and the other from the Danish National Test Station at Østerild.

  • Risø Data - available here (zip file)
  • Østerild Data - available here (zip file)

Legends to use with these files are available here as a zip file. To use these legends, please unpack the content to your folder with the windPRO 'standards'. Typically this will be within this folder:

c:\WindPRO Data\3.4\Standards

Use DHI-Gras InnoWind Premium Data in windPRO

These data layers are typically used with the forest models in windPRO, i.e. the displacement height calculator and the ORA tool. We have a created a small cheat-sheet that describes how these new data-layers are loaded into the respective objects in windPRO - and how they are 'consumed' in the different calculations.

  • InnoWind data in windPRO - cheat sheet - here (pdf-format)

Please note that the cheat-sheet is also useful for understanding how raster-based data can be 'consumed' in a varity of ways in the different objects in windPRO - and how the data layers are consumed within the various calculations.
