With the release of the data-set "windPRO World Satellite Imagery - 10m", users of windPRO 3.2 now have free access to high-resolution, reliable and near-real time satellite images from anywhere in the world. The color images of terrain, vegetation and urban areas can be a valuable aid when doing roughness classification studies or when you need fully updated maps for a particular area.

Data-set Description

The two polar orbiting Sentinel-2 satellites are a part of the Copernicus Earth Observation system – a large multi-billion euro EU infrastructure project. The 2A-satellite was launched in june 2015 and the 2B in march 2017. Both deliver high-resolution multi-spectral images (in 12 spectral bands) – and has a revisit time of 5 days of any part of the world (but may – off cause – contain some clouds). Resolution of the satellite imagery is dependent on spectral band and ranging from 10 m to 60 m. The different spectral bands can be combined to provide images with specific purposes, e.g. highlighting urban areas or vegetation.

Our "windPRO World Satellite Imagery – 10m" dataset is currently a preview dataset only. It holds a (near) cloud free dataset based on recent Sentinel-2 satellite imagery and it is available from our windPRO 3.2 release. We are continuously updating the dataset as new satellite images become available, so expect significant improvements to this dataset. At present, a true-color imagery map is available. More false-color images may be added later to ease identification of urban and vegetation areas.

Access, Resolution and Coverage

• Access: Is from within the 'Dynamic Maps' section in the windPRO background map area. You need a windPRO version 3.2+ to access the data.
• Resolution: The maximum spatial resolution is 10 m per pixel. Most data are from the period 2016 and later.
• Coverage: The "WindPRO World Satellite Imagery" dataset covers most of the globe, except the ocean areas.

Known Issues

Please note, that this is a preview data-set, so data sources and images are still being obtained and processed. So currently, you will might see a few areas to hold inconsistencies, such as:

1. No data coverage - as data has still not been downloaded
2. Various levels of cloud cover - as a cloud free image might not exists
3. Very dark or light areas - as no brightness adjustment has been made (yet)
