DESCRIPTION¶
i.fusion.brovey performs a Brovey transformation using three multispectral and the panchromatic satellite image scene channels. Three new channels are calculated according to the formula:DN_b1
DN_fused = ------------------------------- * DN_pan
DN_b1 + DN_b2 + DN_b3
NOTES¶
The command changes temporarily to the high resolution of the panchromatic channels for creating the three output channels, then restores the previous region settings. The current region coordinates are respected. The three pan-sharpened output channels may be combined with d.rgb or r.composite.EXAMPLE¶
Calculation of Brovey fusion map from North Carolina Landsat scene:ms3=lsat7_2002_50 pan=lsat7_2002_80 \
outputprefix=brovey
