What is the difference between spectral and spatial resolution?

Question

Accepted Answer

Spectral resolution refers to the ability to distinguish between different wavelengths of electromagnetic radiation, while spatial resolution refers to the ability to distinguish between different locations on the ground.

Spectral resolution is measured in terms of the number of bands in an image and the width of each band.
Spatial resolution is measured in terms of the size of each pixel in an image.
Higher spectral resolution allows for more detailed analysis of the composition of an area, while higher spatial resolution allows for more detailed analysis of the features within an area.
For example, a satellite image with high spectral resolution might be able to distinguish between different types of vegetation, while a satellite image with high spatial resolution might be able to distinguish between individual trees.
