Urban monitoring from infrared images

Starting from an experimental campaign in Milan, the article describes how the infrared signal recorded by Landsat 8 sensors can be used to evaluate and monitor the main urban scale environmental variables. The possibility to combine different spectral bands of infrared signal with other spectral bands is highlighted. The monitored variables have been mapped in georeferenced images using the GIS instruments. In this way, a mapping database is achieved and it can be used as a basis of information to study the urban heat islands (UHI) and the environmental changes over the years.
