How to get latest picture of my city from sentinel 2?

Question

I was trying to get latest picture of my city from Sentinel 2, but had no success.
I have registered on Copernicus website, found my city and drew a square around it.
Then I clicked the "search" icon, but all pictures it turned up seem to be "broken" in different ways:

• partial (triangle-like, or trapezoid-like)
• totaly black
• totaly white
• white with acidy-green (not grass) pieces in it.

I thought that I had choosen a wrong sensor, but in a downloaded archive I found JPEG2000 files for different bands - including bands 2,3,4 which I need.

My question is, how to download a google maps-like RGB picture from Sentinel 2.

I have heard that I can get 300m/pixel picture resolution. Is it right?

Answer 1

First of all, the Copernicus website is adequate, but not really user friendly - in my opinion. Sometimes you need a bit determiniation in order to get your desired images, especially when downloads fail. On the other hand the data is free.

First step when trying to download data: log into the website. Otherwise your search results will be gone and you have to start over.

Then create a "filter" by only allowing data from Sentinel 2 to pop up in your search results (button to the left of the search field). Then draw your square/bounding box and click the search-button - as you already did. Now it's time to weed out the low quality pictures. Sometimes there are lots of clouds in the image, sometimes the image mainly consists of black areas (this is due to the fact that the image-stripes the satellite produces are not aligned to the north, but rather north-north-east - caused by its orbit - while the processed images are aligned to the north).

Simply scroll down the list of your search results until you find an image which is a) mostly free of clouds, b) definitely covers your city and c) was recently taken. Often useful results are on page 2, 3 or even 4, but especially after this summer you shouldn't be hard-pressed to find an useful image not older than 3 months.

Have you tried Sentinel Playground or EO Browser?

Playground allows users to "fool around” with global archive of Sentinel-2 and Landsat-8, while eo-browser will give you even more datasets and some nice features (like creating time-lapses, possibility to download your area-of-interest, etc.) if you sign up for free account.
