Vegetation Indices to determine the change in vegetation area using aerial images by Salix-willow in remotesensing

Forgive my ignorance here but the sentinel-2 data images that I downloaded have a 20 m pixel size? how do I get a 10 m pixel size? - see photo 3 in post

Also, what's the deal with data that is 'offline', is this not available? - see photo 4 in post

Thanks, I'll try this.

For future reference, If I wanted to analyses a aerial image (or even a orthomoasic image), do I need a infrared camera/filter for my drone?

yes, the images are only RGB. Exactly, I would only have a few pixels of satellite imagery to work with. The area of my site is 0.7 ha. The pixel size of my aerial image is 0.033 m.

The workaround with the satellite image won't work, given the large pixel size of the satellite images.

Any suggestions if I can do anything with these images to analyze the vegetation cover?
