IBL Warsaw further used the detected extend of the damage area together with the data contained in the Forestry Data Base and calculated the overall amount of timber to be collected from this area. Afterwards, the results have been compared to the figures calculated by the inventory groups (BULiGL) and they were to 98,3% accurate.
