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 having 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
• Themaric 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 is used as the default when the data is loaded into the area-object or line-object.
