The technical field to which invention belongs: Biomath presumption method of the forest trees and shrubs which utilize the remote sensing high resolution data from the high ground.Technical problem: After the afforesting for the prompt naturally young growth and young wood the forest trees and shrubs and the maturity wood which the canopy has not blocked being, even with when they are the forest kind of trees and shrubs which the canopy does not block, it presumes the biomath of specific tree kind at high accuracy.Solution method: As high resolution - to photograph the super high resolution photograph (11), to take in that photograph (12), the masking doing the part other than specific tree kind (13), the result of the masking canopy size (area, length and breadth) of the specific tree kind which remains is measured in the computer, making use of the high resolution satellite and the aircraft and the radio helicopter etc (14), measuring the spectral characteristics of that specific tree kind (15), biomath of specific tree kind is calculated from canopy size (area, length and breadth) and spectral characteristics (16). In addition, to calculate the annual biomath accumulation quantity (17), the result is printed out on the basis of this biomath calculation value, (18).
