Geology
English term or phrase: band arithmetics
First, decide what you want to focus on. If you want to classify different types of vegetation, training fields will be chosen differently than if you want to distinguish lava from vegetation or other features. This exercise has two objectives:

• First: detect lava. The detected lava will serve for post-classification change detection later on. That means that changes will be assessed by performing *band arithmetics* of the classification results.
• Second: identify cities, villages, and roads.

calcolo aritmetico banda


Explanation:
"Tuttavia, le tecniche di rilevamento remoto offrono alcune soluzioni a questo problema. Il calcolo aritmetico banda Landsat 1 - banda Landsat 4, ad esempio, genera una riflessione molto forte delle aree edificate e una minore riflessione di quelle più rurali."

Reference information:
Non so se sia questo.

The band arithmetic tool is used to create new image sample values derived from existing bands, tie-point grids and flags. The source data can originate from all currently open and spatially compatible input products. The source data is combined by an arithmetic expression to generate the target data. By default, a new image view is automatically opened for the new sample values. You can disable this behaviour in the preferences dialog.
