Check out this new ESRI course that features Planet imagery: Explore imagery - Spectral resolution!!
An important characteristic of imagery data is its resolution. There are four types of resolution: spatial, temporal, spectral, and radiometric, as illustrated in our growing tutorial series Explore imagery resolution. In this tutorial, you'll learn about spectral resolution.
You'll become familiar with several concepts such as spectral resolution, spectral bands, multispectral imagery, band combination, and spectral profile. You'll examine and manipulate satellite imagery of different spectral resolutions in ArcGIS Pro, with a focus on the region of Brandenburg, Germany. Finally, you'll learn how to change the number of spectral bands in your imagery.
