Dear all,
which tool is the advisable to trace water ponds or swimming poolls (i.e. small amount of water) from the sattelites?

Hi Pavlos,
The typical size of a swimming pool is around 9,5 * 5 meters. With the open satellite sensors available, you will struggle to identify pools, as they will occupy less than a pixel. You can barely pick out pools (you get a hint there are some, but that’s it) using Sentinel-2: example, which can clearly be seen in high-resolution imagery.
For this application, I would suggest you look at the commercial data offering in Sentinel Hub, which provides sensors with resolutions high enough for your application. I would say World View could be an ideal sensor.
For water ponds, it depends how big they are. I would suggest you explore using EO Browser to see if any open data are suitable.
