EasyKrig 2.0 -- A convenient tool for geostatistics
It is well known that
kriging is a statistic method that provides best linear unbiased
estimation (BLUE). As a geostatistical tool, kriging has been widely
used in mining, geology, hydrology and oceanography. However, one of
the difficulties in using the existing kriging toolboxes is the
knowledge of defining the necessary parameters to run the programs,
especially for people who are not very familiar with kriging.
EasyKrig is a Matlab program package allowing users to process the
data using the kriging technique. EasyKrig is graphic user interface
(GUI) driven and user friendly software package. One of the biggest
advantages of EasyKrig is its ease of use. A user who is not very
familiar with kriging is able to use the program to process his/her
own data and obtain satisfactory results with very limited
EasyKrig2.0 is an updated
version of Easykrig1.0 which was released November, 1999.

Since the release of
EasyKrig1.0 last year, we have received many positive responses
including suggestions and recommendations from users from many
countries. Based on version 1.0, EasyKrig2.0 has greatly improved its
- define a suitable
window size and position by the user. This new feature can solve the
problem that the display window could be off-centered when running
on machines having different screen resolutions.
- handle the different
types of input files: Variables of the x and y-axes of a 2D profile
are not restricted to latitude/longitude, or X(km)/Y(km) anymore,
they can be any type of variables (depth, time, longitude, latitude,
range, etc.) and any unit (km, m, sec., deg, etc.). The new version
also allows users to provide their own program to load the data into
- include the
anisotropic feature in the raw data. The added 2D variogram
capability allows users to specify the optimum anisotropic
parameters, orientation angle and the aspect ratio, and to achieve
the best kriging results.
- perform batch file
processing. This feature will greatly reduce the amount of time to
process a group of files that have the same variogram and kriging
parameters. In batch file processing mode, the program will
automatically process and save all kriging results to output files,
one output file corresponding to an input file.
- perform cross
validation of the kriging model. Several validation models provide
useful information for user to evaluate their results.
- provide more
