WindPRO Global Satellite Imagery
Introduction
With the release of the "windPRO Global Satellite Imagery - 10m" dataset, 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 undertaking roughness classification studies or when you need fully updated maps for a particular area.
Dataset 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 satellites deliver high-resolution multi-spectral images (in 12 spectral bands) – and have a revisit time of 5 days over any part of the world (but the time of the visit may, of course, coincide with cloudy conditions). 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. true-color (RGB-images), highlighting urban areas or vegetation.
Our "windPRO Global 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. 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: From within the 'Dynamic Maps' section in the windPRO background map area. You will need a windPRO version 3.2+ and and active service agreement 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 Global Satellite Imagery" dataset covers most of the globe, except the ocean areas.
Known Issues
Please note, that this is a preview dataset, so data sources and images are still being obtained and processed. Currently, you will might see a few areas with inconsistencies, such as:
- No data coverage - as data have still not been downloaded
- Various levels of cloud cover - as a cloud-free image might not exist
- Very dark or light parts of the image - as brightness adjustments have not yet been made
