Abstract

Estimations of wood volume and age were made for Alvsbyn Kommun using SPOT satellite data
and National Forest Inventory data. Two scenes of satellite data from 1996 were used, and NFI
data from 1990-1998 were used for the estimation. The method used to make the estimates was k
Nearest Neighbor. Problems were encountered with estimates of clearcuts in one of the scenes,
most likely due to a late acquisition date (September 18) at a high latitude, and a sun angle of 25°.
An illumination correction was performed with a 50m resolution DEM, and extra low volume plots
were added; results were improved. The total wood volume RMSE was 69% for the eastern SPOT
scene and 80% for the western scene. RMSE for age was assessed for the eastern scene at 53% .
