Kriging

Kriging and inverse distance are popular interpolation methods, especially in earth sciences. There are some routines already available on matlab but are severely limited by matlabs memory constraints. By using gstat to handle interpolation and variogram modelling, very large datasets are easily...

This function completes what I have started with the functions variogram and variogramfit. It is not intended to be a highly optimized code for performing kriging but may have educational value. Note that for using kriging, you should download the latest version of variogramfit.kriging uses...

The program is designed to interpolate values on a regular two-dimensional grid using ordinary kriging. By slightly modifying the code it is also possible to use simple kriging. The grid of estimated or "kriged" values is rectangular and spans the range of coordinates in the dataset of sampled...

SurGe is a computer program which enables to generate surface as an interpolation (approximation) function of two independent variables. The program has the following basic features: > Implements an interpolation / approximation method called ABOS. > Basic input is a simple ASCII file...

Due to participation from research centre CERENA in the international desertwatch project (homepage software needed to be made to handle the extensive databases necessary to this project successfull completion. ECMWF Parser was one such case and by now the most compreheensive tool built for...

jk3d is a java code for 3d interpolation of scattered data. jk3d uses a quality weighted ordinary Kriging method and optional an inverse distances weighting method. It has no graphical user interface and uses ASCII files to define the input.

Given a list of d-dimensional points -- typically, though not necessarily, representing a mesh -- and correlation information, the function randomfield.m returns realizations of a corresponding random process. These fields may be conditioned on known data values.The correlation information can...
