Label | Explanation | Data Type |
Input surface raster | The input surface raster. | Raster Layer |
Output geomorphons raster (Optional) | Each geomorphon pattern will be assigned a unique identifier, which is stored for each cell in the output geomorphons raster. The output is of integer type. | Raster Dataset |
Flat terrain angle threshold (Optional) | The angle threshold (in degrees) below which the target cell will be classified as flat. The default value is 1 degree. Specifying a larger value than the default is recommended for low resolution DEMs. | Double |
Distance units (Optional) | Specifies the distance unit that will be used for the Search distance and Skip distance parameters. Distance will be measured in the specified unit or number of cells. The default is Cells.
| String |
Search distance (Optional) | The distance away from the target cell that defines the radius of the area that will be used to identify the geomorphon pattern. The default value is 10. Use a search distance value that matches the type and size of the landforms that you want to classify. | Double |
Skip distance (Optional) | The distance away from the target cell where the analysis area starts. Neighboring cells that fall within this distance will be skipped and won't contribute to identification of the geomorphon pattern. The classification of each individual cell is determined by assessing the neighboring cells within the skip distance from the target cell center. | Double |
Z unit (Optional) | Specifies the linear unit that will be used for vertical z-values. It is defined by a vertical coordinate system if it exists. If a vertical coordinate system does not exist, define the z-unit using the unit list to ensure correct geodesic computation. The default is meter.

Return Value
Label | Explanation | Data Type | Output landforms raster | The output classified landforms raster. The output is of integer type. Each value corresponds to a specific landform type: Flat—cell value 1, Peak—cell value 2, Ridge—cell value 3, Shoulder—cell value 4, Spur—cell value 5, Slope—cell value 6, Hollow—cell value 7, Footslope—cell value 8, Valley—cell value 9, Pit—cell value 10. | Raster |
