Im trying to compare classification products of sentinel 2 and landsat 8!
The spectrum is from 440nm to 2200nm.
For sentinel 2, this means that i have to merge bands from different resolutions (2,3,4 from 10 m and 8a,11,12 from 20 m).
Why does Sentinel 2-20 m data has available all bands and not only those pre mentioned?
Should i just merge all bands of interest from 20 m resolution and then resample the multispectral img to 30 m so i can compare them with landsat 8?
Or should i resample the bands 2,3-4 from 10 m to 20 m then stack them together and then resample again to 30 m?
What do you suggest?
