1. Resolution

2. Resolution is
The ability of an optical system to distinguish between signals that are spatially near or spectrally similar.
Spatial
Spectral
Temporal
Radiometric

3. Spatial resolution
Pixel size or IFOV

4. 1, 10, and 30m resolutions

6. Spectral Resolution
Dimension and number of specific wavelength intervals in the EM spectrum to which a sensor is sensitive

9. Temporal Resolution How often the same area is recorded.
Ie. 16 days for Landsat

10. Radiometric Resolution
Sensitivity of the instrument
6 bit (MSS), 64 levels
8 bit (TM 4-7), 256 levels.
12 bit Landsat 8, 4096 levels
