Sentinel is the buzzword for a series of Earth observation missions like Sentinel-1 (Land and Ocean monitoring,launched in April 2014), Sentinel-2 (land monitoring, launched in June 2015) and Sentinel-3 (marine monitoring, launched 16th of Feb 2016) and many more are planned. But how to get the data? Check it out in this post
Since the start of Google Earth in 2001 (it was re-released in 2005 after Google acquired it from Keyhole, Inc ) remote sensing images made their way into every day life. But if you are looking at the images they show on Google Earth or Google Maps: You will see historic data and it strongly depends on companies like Digital Globe, BlackBridge (a.k.a. RapidEye) or Astrium and the contracts with Google whether you will see new or old data.
Thanks to a post from the mapbox colleagues I’ve found out that new Landsat 8 scenes are already available on EarthExplorer. The data is great!!!
