Description: <DIV STYLE="text-align:Left;"><DIV><DIV>RS-FRIS is a remote-sensing based forest inventory for WA DNR State Trust lands. RS-FRIS predicts forest conditions using statistical models that relate field measurements to three-dimensional remotely-sensed data (DAP and LiDAR point clouds). Forest metrics are predicted at a scale of 1/10th acre and stored as rasters. The attributes of each RIU are calculated as the mean of the raster cell values that fall within each polygon. Note: origin year and age are exceptions, and are based on the median value.RS-FRIS 5.1 was constructed using remote-sensing data collected in 2021 and 2022. Version 5.1 incorporates depletions for selected completed harvest types through 2024-09-17.Last edit date: 2024-09-09<TABLE><TBODY><TR><TD>Name</TD><TD>Description</TD><TD>Units</TD></TR><TR><TD>RIU_ID</TD><TD>Unique identifier for each inventory unit.</TD><TD>n/a</TD></TR><TR><TD>LAND_COV_CD</TD><TD>Land cover code.</TD><TD>n/a</TD></TR><TR><TD>LAND_COV_NM</TD><TD>Land cover name.</TD><TD>n/a</TD></TR><TR><TD>AGE</TD><TD>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).
