Corine Land Cover

Introduction

Corine 2018: Data in windPRO. Wind farm west of Hamburg, Germany.

Coverage of the Corine 2018 dataset.

Corine land cover products in windPRO are data-layers from years 2006, 2012 and 2018. National centres for land-cover analysis are producing the datasets - with the majority of the national authorities using visual interpretation of high resolution satellite imagery. In some countries other semi-automatic methods are applied using national in-situ data, satellite imagery and GIS-tools. The dataset has a legend with 44 classes of land-cover. These have been mapped in to roughness lengths for use in WindPRO. It is produced and delivered by the European Environment Agency (EEA) - http://www.eea.europa.eu/ through the Copernicus Land Monitoring Service.

Dataset Overview

• Spatial Coverage: This dataset covers most parts of Europe, with the recent version coverage of 39 countries.
• Resolution: 100 m.
• Data Type: Land Cover / Land Use Mapping - with roughness length mapping by EMD (lookup table)
• Versions:
  • 2018: Representing a time consistency 2017 - 2018
  • 2012: Representing a time consistency 2011 - 2012
  • 2006: Representing a time consistency 2006 +/- 1 year
• Geomeric Accuracy (Satellite Data):
  • 2018: <10m (based on Sentinel-2 imagery)
  • 2012: <25m
  • 2006: <25m
• Thematic Accuracy: >85%

Availability from within WindPRO

The data are available directly from within windPRO. The data can be accessed from the online-services in the following objects:

• Area Object (with purpose set to 'roughness map based on closed lines')
• Line Object (with purpose set to 'roughness lines')

Please note: Data stored in the 'Area Object' can be (fairly) easily edited by changing the legend / lookup-table definitions - as this data-type preserves the original metadata (land cover groups). This is not possible when loading roughness-lines data directy in the line object.

Usage Notes

1. Always make a manual evaluation and adjustment of the roughness lengths obtained from this dataset; they are based on a simplified lookup table (as seen below) and you may find that any in-situ values will differ from the model values obtained from the lookup table.
2. If you want to modify the values obtained: Load the data into a windPRO area object.

Legends

The Corine Land Cover Datasets (2006, 2012 and 2018) datasets have 44 different categories that EMD has mapped in to a suggested roughness length, z0. The values from the column 'EMD Roughness Length' in the lookup-table (LUT) below are used as defaults when the data is loaded into the area-object or line-object. The comparson to the DTU default LUT-values are shown as an additional column. This is done to highlight that the lookup-table values are uncertain, and likely to be dependent of the geographical region where they are applied and also the expert making the estimate. As such, the used values should be validated, e.g. using local mast data (the wind profile) and by cross-predictions between masts.
