文摘
- •
Satellite-derived canopy heights and spectral data were successfully combined to estimate growing stock.
- •
The combined use of spectral and height information outperformed the sole use of either spectral or height data.
- •
Spatially detailed and accurate maps were generated, displaying the distribution of growing stock within the forest.
- •
20">The developed moving window (MW) approach proved very efficient for map generation.
- •
25">Validation of the estimated growing stocks at plot and stand level.
