About Geostatistics Kitchen



This website chronicles the geostatistical programming tools developed when I was working full-time at the research center CERENA (Geostatistics and Georesources) at my Alma Mater (Instituto Superior Técnico).

This programming effort was mainly focused on Geostatistical tools developed in Mathematica which were to be released here as a complete package (GeoPack 2.0). Although the code exists, that never came to be ,as the code is very large and is mostly poorly documented.

This is why a new approach will be here presented and hopefully some of you will benefit also. You can also check on progress achieved below in the kitchen blog and retrieve course materials from my teaching at the Catholic University of Angola here

Any further inquires, feel free to drop me a line (João Carneiro).

"Green Fairy" Alpha 2 due for next week

posted 12 Oct 2016, 14:57 by João Carneiro

Work on the second Alpha of GSK GeoPack 2.0 "Green Fairy" continues on a leisurely pace. Has you might know, this second alpha will add kriging (ordinary and simple) and Sequential Gaussian Simulation to "Green Fairy" and represents a major milestone in terms of usability as from this point on, "Green Fairy" will surpass the capabilities of GSK GeoPack 1.1. The kriging implementation is much faster at is basis and on top of that can use the multi-processing abilities of Mathematica.

This release will also include some bugfixes on previously released code and some tutorial notebooks. A teaser image of Sequential Gaussian Simulation has you will find in the tutorial notebooks being built right now is shown below. Its a classical test data set of lead contamination with 99 samples available (which is also part of the kitchen's site graphics at this time!).


Work on Second "Green Fairy" started (and other stuff...)

posted 30 Sep 2016, 11:00 by João Carneiro

After a break that lasted from the 1st of August to today, again time is available to proceed with GSK GeoPack 2.0. Work on the second Alpha (go here to have a feature list) has been started today and its release is expected before the end of October (no promises).
The Alpha 2 release will exceed by far in capabilities and performance the now very old GSK GeoPack 1.1 and will be much more useful as kriging and SGS will be included. 

In parallel with the review and release of "Green Fairy" Alphas, other projects are on the forge that will cross to new realms: additionally to the "Geostatistics" keyword, two additional ones will be added to the kitchen mantras: "Python" and "Machine Learning". 
One will be dropped: "Mathematica" :( ...





GSK GeoPack 2.0 Alpha 1 released

posted 21 Jul 2016, 19:00 by João Carneiro   [ updated 21 Jul 2016, 19:06 ]

The phased approach here stated for GSK GeoPack 2.0 code release is starting to payoff: It is now made available for those of you who are curious, all the packages that lay the foundations of GeoPack 2.0 and that already allow to perform spatial covariance analysis (2D and 3D).

You have at your disposal routines that can be used interactively to build a covariance model (ready to be used in simulation/kriging routines although these are not yet available) or you can build your own spatial templates to perform spatial covariance analysis that goes beyond bi-point statistics. In the Picture below, three experimental variogram spatial templates can be observed (and you can try them!).

Experimental Variogram Spatial Template


Check out for yourself but be reminded that proper commenting is not yet complete on the available files and that no decent tutorial yet exists (only a lousy one :) ).
A word of caution: Mind that this code is in Alpha stage code will certainly still be subject to major changes!




Fresh Face for New times!

posted 12 Jul 2016, 03:45 by João Carneiro   [ updated 12 Jul 2016, 03:47 ]

After more than a year of complete silence, the kitchen site is going to a complete overhaul. New times require a fresh image and the chef is quite pleased with the new looks!
But looks are not the only thing that matter so new content has been added: SLB ECLIPSE tutorials (available in english), class materials on reservoir engineering and Geostatistics (in portuguese).

The mountain of Mathematica code that is is storage is going finally find itself posted in the next few weeks in here. Stay Tuned cause the kitchen is back!

T-9: Variogram Modeller Part 3

posted 22 Jul 2014, 13:33 by João Carneiro

Extensive testing and some new things are being added to the variogram modeller. Today, a new screen has been added enabling you to select the variogram estimator that you want and also some basic analysis of the base dataset (to make sure that everything works fine). Here's the screenshot of the new settings window that gskModeller gained today:

T-10: The Variogram Modeller Part 2

posted 21 Jul 2014, 11:38 by João Carneiro   [ updated 12 Jul 2016, 03:47 ]

It will be possible for you to save your variogram modelling session on disk and on a single file. Here's a screenshot of the evolving Modeller Tool as it is right now:


T-13: New Variogram Modeller

posted 18 Jul 2014, 12:28 by João Carneiro   [ updated 30 Sep 2016, 11:02 ]

The Variogram Modelling in GeoPack 2.0 is completely interactive. Today the modeller gained a place where several models can be stacked enabling you to choose the one you think its best for your data. Here's a screenshot of it looks right now:


T-14: Ville du Quebec is going to be "GSKfied" ...

posted 17 Jul 2014, 12:01 by João Carneiro

Tomorrow morning, at the IGARSS 2014 conference being held in Quebec City, results produced with GeoPack 2.0 will be shown. If you happen to be there, here's the name of the presentation: Beyond the confusion matrix: geostatistcal error assessment for Landsat derived landcover maps of the Portuguese landscape. Look for it on IEEE IGARSS 2014


T-15: Irregular Block Covariances

posted 16 Jul 2014, 05:19 by João Carneiro   [ updated 16 Jul 2014, 06:02 ]

Fitteen days away from the release of GSK GeoPack 2.0, The variogram modeller is up and running and a very basic tutorial for it is now built. Next stop and objective for today: Calculation of covariances based on irregular support. In the shown picture, covariances for a channel structure can be observed. They are obtained as a result from the convolution of a given variogram model and the points which a given block occupies in space.
