Description Usage Arguments Details
This function automates the calculation of a layer stack of predictor layers to use in a land use and/or land cover classification. See Details for the output layers.

file extension to use when saving output rasters (determines output file format). |

The layers in the output layer stack are listed below. Note that all the layers are rescaled so that they range between -32,767 and 32,767 (allowing them to be stored as 16 bit unsigned integers).
Predictor layer stack:
Layer 1: | Band 1 reflectance |
Layer 2: | Band 2 reflectance |
Layer 3: | Band 3 reflectance |
Layer 4: | Band 4 reflectance |
Layer 5: | Band 5 reflectance |
Layer 6: | Band 7 reflectance |
Layer 7: | MSAVI2 |
Layer 8: | GLCM mean (from MSAVI2) |
Layer 9: | GLCM variance (from MSAVI2) |
Layer 10: | GLCM dissimilarity (from MSAVI2) |
Layer 11: | Elevation |
Layer 12: | Slope (radians X 10000) |
Layer 13: | Aspect (see below) |
The aspect is recoded as:
Aspect coding:
1: | north facing (0-45 degrees, 315-360 degrees) |
2: | east facing (45-135 degrees) |
3: | south facing (135-225 degrees) |
4: | west facing (225-315 degrees) |
