Vertex TypechoiceVERTEXAvailable Choices:
[0] x, y
[1] x, y, z
Default: 0
Parallel ProcessingbooleanLINE_OMPDefault: 1
Split Line PartsbooleanLINE_PARTSDefault: 1
Parallel ProcessingbooleanPOLY_OMPDefault: 1
Split Polygon PartschoicePOLY_PARTSChoose '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 FixbooleanPRECISIONCheck to avoid coordinate precision issues with polygon construction, particularly helpful with geographic coordinates or in general with comparatively small cell sizes.Default: 0
Interpolation Scalefloating point numberSCALEset greater one for line smoothingMinimum: 0.000000
Default: 1.000000
Boundary ExtensionbooleanBOUNDARYExtend contours beyond boundary. Internally input grid is extrapolated by one cell size in each direction (top, down, left, right).Default: 0
