Parameters
|  | Name | Type | Identifier | Description | Constraints | 
|---|
| Input | Features | grid list, input | FEATURES | - | - | 
| Training Samples | table, input | TRAIN_SAMPLES | Provide a class identifier in the first field followed by sample data corresponding to the input feature grids. | - | 
| Training Areas | shapes, input | TRAIN_AREAS | - | - | 
| Output | Classification | grid, output | CLASSES | - | - | 
| Probability | grid, output, optional | PROBABILITY | - | - | 
| Look-up Table | table, output, optional | CLASSES_LUT | A reference list of the grid values that have been assigned to the training classes. | - | 
| Options | Normalize | boolean | NORMALIZE | - | Default: 0 | 
| Colors from Features | boolean
[GUI] | RGB_COLORS | Use the first three features in list to obtain blue, green, red components for class colour in look-up table. | Default: 0 | 
| Grid System | grid system | GRID_SYSTEM | - | - | 
| Training | choice | MODEL_TRAIN | - | Available Choices:
[0] training areas
[1] training samples
[2] load from file
Default: 0 | 
| Class Identifier | table field | TRAIN_CLASS | - | - | 
| Buffer Size | floating point number | TRAIN_BUFFER | For non-polygon type training areas, creates a buffer with a diameter of specified size. | Minimum: 0.000000
Default: 1.000000 | 
| Load Model | file path | MODEL_LOAD | Use a model previously stored to file. | - | 
| Save Model | file path | MODEL_SAVE | Stores model to file to be used for subsequent classifications instead of training areas. | - |
