RE: GEOSTATS: GIS Software - what about
Even I am not really familiar with AutoCAD Map I do know that there exists a
Geostatistical tool for AutoCAD. The review I have is unfortunately from
1996, but the program is for sure available now for ACAD R14. Its name is
QuickSurf, from Schreiber Instruments and it can do a lot of different sorts
of surface modeling, including TIN's, Trend Surface, Kriging and Continuos
curvature. It is regarded as one of the fastest surface generating programs
available and has a lot of tools for manipulating and shaping surfaces and
is best used in civil engineering and landscape architecture. It costs
around US$ 1,200.-.
Another one is SiteWorks from Intergraph which is available for AutoCAD or
Microstation and is also said to be best used for Engineering applications.
But it is just capable of TIN's and Trend surfaces. But in what it is doing
it is supposed to be very good (Cost around 1,500.- US$).
For more information you should look up following reference (as I said it
might be already little bit out of date but gives you some idea what is
available and you can look up the web sites of the respective companies for
more current versions):
Thoen, Bill (1996) Explore the Third Dimension; A comparative Review of
Contouring Products for Windows 95, GIS World, December 1996, p. 51-59.
To your question which program is easiest to learn, I would say that is
dependent very much on your background knowledge and much more on what you
want to do with "Geostatistics". If you just need a mapping and contouring
program than I would recommend Surfer for Windows, which is cheap (about
500.- US$) and easy to learn, but very powerful. It can be extended in its
geostatistical capabilities by using the program VARIOWIN for semivariogram
If your are trying to get easily into GIS including "Geostatistical"
capabilities included, than I would recommend IDRISI32, the newest version
of this GIS program, which now includes also geostatistical surface modeling
tools. IDRISI is cheap, easy to learn and very powerful, especially as
Raster GIS and for image processing and analysis.
Hope that helps you get started in your search
