[nugget=semivariogram nugget] [sill=semivariogram sill] [max_lag=max_lag]
DESCRIPTION
Is missing.
Parameters:
- input=name
- Name of input site map
- 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
NOTES
You have to play with the parameters to get a reasonable result and not a
segmentation violation
The module finds semivariance from variogram model for the calculated
distances: This function provides a "modelled" variogram based on the shape, range, sill and nugget determined from the examination of the experimental
variogram. Semivariance values are calculated accordingly.
