| Options | ||||
| Vertex Type | choice | VERTEX | Available Choices: [0] x, y [1] x, y, z Default: 0 | |
| Parallel Processing | boolean | LINE_OMP | Default: 1 | |
| Split Line Parts | boolean | LINE_PARTS | Default: 1 | |
| Parallel Processing | boolean | POLY_OMP | Default: 1 | |
| Split Polygon Parts | choice | POLY_PARTS | Choose 'precise' if you expect complex nestings of islands and lakes (might increase processing time significantly). | Available Choices: [0] do not split [1] split [2] precise Default: 1 |
| Coordinate Precision Fix | boolean | PRECISION | Check to avoid coordinate precision issues with polygon construction, particularly helpful with geographic coordinates or in general with comparatively small cell sizes. | Default: 0 |
| Interpolation Scale | floating point number | SCALE | set greater one for line smoothing | Minimum: 0.000000 Default: 1.000000 |
| Boundary Extension | boolean | BOUNDARY | Extend contours beyond boundary. Internally input grid is extrapolated by one cell size in each direction (top, down, left, right). | Default: 0 |
| Minimum Length | floating point number | MINLENGTH | Contour line segments with minimum length [map units] or less will be removed from resulting data set. | Minimum: 0.000000 Default: 0.000000 |
| Interval Definition | choice | INTERVALS | Available Choices: [0] single value [1] equal intervals [2] from list Default: 1 | |
| Base Contour Value | floating point number | ZMIN | Default: 0.000000 | |
| Maximum Contour Value | floating point number | ZMAX | Default: 1000.000000 | |
| Contour Interval | floating point number | ZSTEP | Minimum: 0.000000 Default: 100.000000 | |
| Contour Values | text | ZLIST | List of comma separated values. | Default: 0, 10, 20, 50, 100, 200, 500, 1000 |
