Function Documentation

void MkrgAdjustVariogramModel (  void *  handle, int  VariogramType, int  DriftOrder, int  NumNearest, int  NumMinimum, DOUBLE  Sill, DOUBLE  Co, DOUBLE  Anisotropy, DOUBLE  Radius1, DOUBLE  Radius2 )

Change some parameters in variogram model. Parameters: Sill  variogram sill value Co  variogram nugget value Anisotropy  anisotropy angle Radius1  search radiuses

int MkrgDisplayVariogram (  void *  handle  )

This function actually opens XYPlot dialog and assign variogram data.

int MkrgGetOutputFiles (  void *  handle, RVCRASTINFO *  sInfo, MIUNICODE *  filename, INT32 *  inode, int  ErrRast, int  DriftRast )

Get output files.

void MkrgGetParms (  void *  handle, double &  Sill, double &  Co )

Get sill and Co parameters. Parameters: Sill  variogram sill value Co  variogram nugget value

int MkrgInit (  void **  handle, DPOINT3D *  Data, INT32  numpts, int  Duplicate )

Init kriging toolkit. 1. This function allocates handle to use with other functions. 2. Creates Q-tree for input data , do not free Data pointer, process needs it. 3. Sets default values for all internal parameters. 4. Run Variogram estimation function. Parameters: handle  Kriging handle

int MkrgRunCrossEstimation (  void *  handle, DOUBLE *  MeanErr, DOUBLE *  StdDev )

Run cross estimation.

int MkrgRunGriding (  void *  handle, DPOINT2D *  UpLeft, DPOINT2D *  BtRight )

Run kriging for output raster. Parameters: handle  output area definition

int MkrgSaveVariogram (  void *  handle  )

Save variogram in the text file.

int MkrgSetOutputRaster (  void *  handle, int  Rastid, RVCRASTINFO *  Info, DOUBLE  minvalue, DOUBLE  maxvalue, int  AutoRescale, int  ErrorRaster, int  DriftRaster )

Set output raster parameters.

int MkrgSetTrimming (  void *  handle, DOUBLE  low, DOUBLE  high )

Set trimming values.

int MkrgSetupKriging (  void *  handle, int  VariogramType, int  DriftOrder, int  NumNearest, int  NumMinimum, DOUBLE  LowTrimF, DOUBLE  HighTrimF )

This process runs variogram estimation and sets up all internal parameters.

int MkrgStop (  void *  handle  )

Close kriging toolkit and free all memory.
