Name	Visibility	Description
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)}
Radius	public	3-sigma ("radius") of the Gaussian distribution.
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)}
