The Coordinate System
The Coordinate system is fixed in the input data file
The input data file contains a section called
"region", which fixes the extent of the 2-dimensional area for
which results will be calculated.
This area is rectangular, but can also be clipped to have another
form for the display of the kriging results.
An example would be (part of an input data file):
The threee lines contain coordinates:
- The botom left corner
- The bottom right corner
- The top left corner
This makes possible to use a rectangle that is not aligned to the
coordinate-system of a map, but can also be turned by some angle.
Optionally the definition of an area may follow.
This is a list of coordinates which define
a polygon in order to clip the region outside this polygon when
displaying kriging results. This list follows immediately after the first
The clipping of the result in the kriging window
The display in the kriging window does not need to show the whole area
for which the calculations have been done.
It is possible to magnify a part of the 2-dimensional result with
the two-dimensional scroll region (and the related
An example in which these options are needed would be an
investigation area with small y-extent and large x-extent. If all of this
area can be seen, then details can not be seen properly. Of course, if
a magnified display is used, only part of the area can be seen, but this
in great detail.
