Description: Number of years since the stand was initiated; a composite of known dates (where recorded in inventory data) and predicted dates (where not recorded in historical inventory data). Calculated as CURRENT YEAR - ORIGIN_YEAR.
RS-FRIS 4.0 was constructed using remote-sensing data collected in 2019 and 2020. Origin year and age are periodically updated to reflect harvest activities; all other attributes continue to report conditions as shown in the remote sensing data.
