Name: RS-FRIS 5.2 RIU Polygons

Display Field: RIU_ID

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: 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 5.2 was constructed using remote-sensing data collected in 2021 and 2022. Version 5.2 incorporates depletions for selected completed harvest types through 2024-12-31.Last edit date: 2024-10-17NameDescriptionUnitsRIU_IDUnique identifier for each inventory unit.n/aLAND_COV_CDLand cover code.n/aLAND_COV_NMLand cover name.n/aAGENumber 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).
