Copernicus will deliver an unprecedented volume of free data, provide new operational services and foster new business opportunities and job creation.The data itself is collected since 2014 (Sentinel 1A) and the operation is scheduled to deliver data till 2020 at least. But how to get the data into the GIS of your choice.
Sentinel Data in QGISThe easiest way to get Sentinel images into QGIS might be the SCP or Semi-Automatic Classification Plugin by Luca Congedo:
The Semi-Automatic Classification Plugin (SCP) allows for the supervised classification of remote sensing images, providing tools for the download, the preprocessing and postprocessing of images. Search and download is available for ASTER, Landsat, MODIS, Sentinel-2, and Sentinel-3 images.So use your Copernicus account inside the SCP plugin, select your area of interest, and click find. Of course you should decrease the max. percentage of cloud cover to your needs. The data is downloaded as a tif file to your local pc. Once you have the data you can use them under the “Creative Commons CC BY-SA 3.0 IGO licence”:
Unfortunately the search, preview and download inside the plugin is very slow and also caused some error messages inside QGIS… If you want to see it in action:
Sentinel Data in ArcGISEsri announced, that they will feature Sentinel-2 images in their Living Atlas of The World. But you need some sort of account. Maybe you use the free of charge developer account to view the data. Yet this data collection only serve the RGB-combination. It is available in your Portal-item in the Catalog in ArcGIS Pro/ArcMap: As you can see, part of the view: all scenes are available but hard to filter. Yet the meta-data of these scenes seem to be “not defined”. That makes search quite hard. But keep in mind:
The ArcGIS Living Atlas of the World is the foremost collection of geographic information from around the globe. It includes maps, apps, and data layers to support your work.So if you want to get a real inside and not only “support” you might want to use the Data collection with preprocessed data: So it possible to select the image service and define the processing template inside the service in ArcGIS Pro. Preconfiugured services are:
- Short-wave Infrared with DRA
- Geology with DRA
- Natural Color
- Short-wave Infrared
- NDVI Colormap and colorized
