fluvial lines from DEMs
Looking for downloadable resent and old review papers of
geostatistics, and if it has something of history I will be really happy.

Im looking for downloadable manuals of avenue
for ArcView Gis 3.x. Im beginning to learn these, but I have experience in
programming with Visual Basic. It is possible to create a link with ArcView Gis
3.x. objects in dlls and link inside ArcView Gis 3.x avenue code any ActiveX or
standard
Im
working in a new method of estimation, but I have to programming a little, some
know the existence of free code in Vbasic, Matlab, C#, or other of some
kriging software, and experimental variogram for make the changes to the new
method more easy (Ill use the search ellipsoid, etc
)

If are you windows user
a) Open a DOS windows (symbol of the system, or type command) (Shell
windows)
b) Inter in the gslib directory (ex. cd C:\GSLIB\)
c) Type the name and parameters (ex. gamv c:\gslib\paramet\gamv.par)
a. If you use 3th parameter the output will occur i
Hell dear mail list member.
I'm interesting the mathematic demonstration of valid variograms function,
and then, I'm looking for papers abut that. Some one can help me, or send me
some paper, or gave me the URL with information abut that? (Specially if
have been written by Matheron)

Dear
mail list there are the answers to the simulate in block support
question:
You
have to simulate in an SMU scale and after that migrate to your block
support.
For
example:
If
you want to simulate a 10x10 block, you can use a 1x1 simulation grid and after
that migrate this 1x1 s

I
have a theory question that many peoples may be are interesting to know, it is
about screen effect.
In
these case screen effect cause the screening of the points in dependence of the
angle, for example if exist 2 points aligned the closed point screening the
How to simulate variables in block
support?
I need to simulate some variables
in block support, as in block Ordinary Kriging. I work with GSLIB.
How to do that???
It can be do, transforming the
initial histogram of point samples to block support, or simulating in a very
dense grid?
Im
interesting in few theorical aspects of geostatistics, today the question is
about
the variogram functions:
a)
What are the properties that need some functions for be considered legal
as Theoric Variogram.
b)
If I put n legal functions in the Kriging Equation it is legal
It is preferable to use another data, I think that it is to spaced an in

using Jacknife technique, I have use to the classical cross correlation but the
error was to small, the samples in vertical holes are to closed in relation to
