DESCRIPTION
Is missing.
Parameters:
- input=name
- Name of input site map
- zdimension=index
- Index of dimension field if appropriate
- znumeric=index
- Index of numeric field if appropriate
- zstring=index
- Index of string field if appropriate
- outz=name
- Name of output z value raster map
- outvarz=name
- Name of output z variance raster map
- outvarz=name
- Name of output z variance raster map
- model=type
- Type of semivariogram model to be used
options: power,spherical,exp,log,gaussian
- npoints=value
- Number of interpolation points
default: 12
- range=value
- Not used with log or power models
default: 1.0
- power=value
- Only for use with the power model
default: 1.0
- nugget=value
- The variogram nugget variance
default: 0.0
- sill=value
- The variogram sill scaled to the sample variance
default: 1.0
- max_lag=value
- The max_lag is only used with the power model
default: 1000.0
NOTE
You have to play with the parameters to get a reasonable result and not a
segmentation violation
At least one of the options zdimension
| znumeric | zstring must be selected and supplied with a valid (0-based)
index value. This will contain the values of the spot heights.
