[MAG33-P06] Inversion of forest structure parameters using multi-source remote sensing data
Keywords:Forest structure parameters, Multi-source, NDTI, Texture
Vegetation indexes used in this article include Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), Soil Adjusted Vegetation Index (SAVI), Modified Soil Adjusted Vegetation Index (MSAVI), Normalized Difference Moisture Index (NDMI). Normalized Difference Time Index is expressed in the following form:
NDTI = (Band Xsummer – Band Xwinter) / (Band Xsummer + Band Xwinter)
Texture factors include Mean, Variance, Homogeneity, Contrast, Dissimilarity, Entropy, Second Moment and Correlation of different convolution window.
The correlation coefficient of the model for average tree height is 0.377, with a standard error of 1.1024 m, for average diameter at breast height(DBH) is 0.422, with a standard error of 1.8684 cm, for volume per hectare is 0.556, with a standard error of 11.8606 m3/ha.This work is still refining according to the needs of forestry production sector.
