Transform

INPUT

Input Data - DEM (Raster Dataset) - a grid representing a continuous surface

COMMAND

Command Call with 4 different transform methods possible

Four transformation methods have been implemented:

• SQR Transform sqr ( input + 0.5 ) to take care of zeros
• Logit Transform (ln ( input / 1 - input ) )
• Z-Transform ( input - mean input ) / standard deviation of input
• Z-Transform2 according to Wendroth et al. (2002): ( input - mean input - 2 x standard deviation of input ) / 4 x standard deviation of input

RESULTS
