These layers show current Resource Inventory Units (RIUs) symbolized using attributes populated from remote-sensing predictions

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 (PhoDAR 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. The attributes represent forest conditions as of mid-2017. Origin year and age are periodically updated to reflect harvest activities; all other attributes continue to report mid-2017 conditions.
