Editing Forest area (global) (section)

== Monitoring and Measurement ==
Forest area is primarily monitored through remote sensing technologies, complemented by ground-based inventories and national forest assessments. Satellite imagery, including data from sensors such as Landsat and MODIS, enables high-resolution mapping of forest cover and changes over time. Analytical methods include classification algorithms, change detection techniques, and time series analysis.

Key institutions involved in monitoring forest area include the Food and Agriculture Organization of the United Nations ([https://en.wikipedia.org/wiki/Food_and_Agriculture_Organization FAO]), which produces the Global Forest Resources Assessment (FRA) every five years. Other contributors include research groups such as those at the University of Maryland and Global Forest Watch, which provide annual tree cover loss data. These datasets support consistent measurement conventions and facilitate international comparisons.

Within the SIGNAL system, this phenomenon is treated as a defined environmental signal whose boundaries and measurement conventions are described below.
