Description
Calculates for each polygon the area covered by each grid class.
Parameters
| | Name | Type | Identifier | Description | Constraints |
|---|
| Input | Polygons | shapes, input | POLYGONS | - | - |
| Classes | grid, input | GRID | - | - |
| Look-up Table | table, input, optional | GRID_LUT | - | - |

| Options | Grid System | grid system | PARAMETERS_GRID_SYSTEM | - | - |
| Processing Order | choice | PROCESS | If only a small part of the grid area is covered by polygons, polygon by polygon processing might give an enormous performance boost. | Available Choices:
[0] cell by cell

[0] cell center
[1] cell area
Default: 0 |
| Output Measurment | choice | OUTPUT | - | Available Choices:
[0] total area
[1] percentage
Default: 0 |
| Class Definition | choice | GRID_VALUES | - | Available Choices:
[0] values are class identifiers
