Name Visibility Description
Assignment public Defines method of assigning point values within each pixel; default is Mean.
Coordinate public Defines which coordinate is taken as interpolation value if the interpolation is not based on an attribute field; default is Z.
(Inherited from TGIS_VectorToGridAbstract)
DefaultValue public If UseDefaultValue is true, then this value will be set for each grid cell for which the interpolated value cannot be computed.
(Inherited from TGIS_VectorToGridAbstract)
DefaultValueFormula public Defines cell assignment method for NoData filling; default is DefaultValue.
Exponent public Exponent in the formula for weight calculation; default value is 2.
UseDefaultValue public If true, then each grid cell for which the interpolated value cannot be computed will be set to DefaultValue.
(Inherited from TGIS_VectorToGridAbstract)
WindowSize public Defines window size for filling NoData process; odd value required, even values will be rounded up; default value is 3.
