Question

Why do thermal bands have larger pixel sizes compared to non-thermal multispectral bands?

Answer 1

● However, high spatial resolution images often lack thermal bands and have limited spectral bands.

So that by above given information we can concludes thermal bands have low spatial resolution image. We also know that the low resolution image have less pixels which gives a bad appearance and not present a clear image.

Now the final conclusion is that if low resolution image have less pixels so there should be Large pixels for covering whole area of the image. therefore this is the basic reason for the thermal bands have large pixels.

if helpful give ?.

thank you.
