Abstract
Methods for forest resources inventory for tropical region were
developed and tested in Lao PDR. The key element of the study was application
of a sample of satellite data with better than one meter ground resolution.
Using a hierarchical approach, information from of sample of very high
resolution (VHR) image data was combined with lower resolution satellite data
of AVNIR and ALOS/PalSAR that were available wall to wall. Theoretical study
with the GlobCover data showed that the same accuracy could be achieved in
forest area estimation with 1 % stratified sample of VHR data as with 6.25 %
non-stratified sample.
Good agreement between the visually interpreted VHR plots and wall to wall
maps was achieved in land cover classification. In the biomass estimation a
value of R2=0.6 was achieved with ground plot test data.
