[ai-geostats] Optimization of monitoring networks
Dear list, Gregoire Dubois has mentioned my dissertation at http://www.math.uni-klu.ac.at/~guspoeck/book.pdf and has also mentioned the fact, that there is some matlab code for network optimization inside. I found two errors in one of my functions called mixedLbx1y1.m. If anybody uses this function, please change the lines x1=[x1;x]; y1=[y1;y]; xstarting=[xstarting;xstarting2']; ystarting=[ystarting;ystarting2']; to x1=[x0;x]; y1=[y0;y]; xstarting=[x;xstarting2']; ystarting=[y;ystarting2']; Next week I will also correct my dissertation at the mentioned http.

AI-GEOSTATS: variogram fitting
Hello Peter, you can find Matlab code for empirical variogram estimation and WLS-fitting in my spatial sampling design toolbox http://www.uni-klu.ac.at/~guspoeck/spatDesign_V.1.0.0.zip Moreover you will find there also functions for Box-Cox transformation and variogram fitting and for Bayesian and trans-Gaussian kriging.

AI-GEOSTATS: spatial sampling design toolbox: spatDesign Version 2.0.0
Dear colleagues, this mail is to announce that Version 2.0.0 of my spatial sampling design MATLAB toolbox spatDesign is published online now at http://wwwu.uni-klu.ac.at/guspoeck/spatDesign_V.2.0.0.zip . The toolbox provides routines for spatial sampling design with the linear Bayesian kriging predictor or the universal kriging predictor. Designs can be improved, design locations can be added to or removed from available designs. Furthermore Bayesian linear kriging and transformed-Gaussian kriging together with routines for semivariogram- and transformation parameter estimation are implemented as interpolation routines. New in Version 2.0.0: Spatial sampling design, Bayesian universal kriging, and iteratively generalized least squares estimation of the covariance function including external drift variables that are defined on a not necessarily regular spatial grid is possible now. Figures of optimal designs are given. Version 2.0.0 replaces Version 1.0.0.. Only one minor change specifying the external drift variables has been made to the function calls of Version 1.0.0.. Version 1.0.0 is still available at http://wwwu.uni-klu.ac.at/guspoeck/spatDesign_V.1.0.0.zip . For details on the implemented algorithms please refer to the papers serra08_pilz_spoeck.pdf and serra09_spoeck_pilz.pdf which are attached to the toolbox.

AI-GEOSTATS: spatial sampling design toolbox: spatDesign
Dear colleagues, for those of you, who have MATLAB not available, I have ported my spatial sampling design toolbox spatDesign also to Octave. Octave is free software and available from http://www.gnu.org/software/octave/ due to John W. Eaton and underlies the GNU public licence. After some minor changes to the original MATLAB code the toolbox is now also almost fully functional in Octave. Read the file README.txt inside the toolboxes for details. There is also a nice new feature in the toolboxes now. Wolfgang Nowak, from the University of Stuttgart has added fast FFT-Kriging code for interpolation in all 3 dimensions. Both toolboxes can be downloaded from: MATLAB: http://wwwu.uni-klu.ac.at/guspoeck/spatDesignMatlab.zip . OCTAVE: http://wwwu.uni-klu.ac.at/guspoeck/spatDesignOctave.zip . With respect to Octave the toolbox is truely public software now.

Dear users of spatDesign, Version 2.1.0 of the spatial sampling design Matlab toolbox spatDesign is now available online at http://wwwu.uni-klu.ac.at/guspoeck/spatDesignMatlab.zip New in this version of spatDesign is an implementation of the Smith and Zhu (2004) design criterion, which takes account also of covariance function uncertainty. Since the computations for this design criterion are computationally very intensive it has been implemented in parallel on NVIDIA GPUs with CUDA support. You need the GPUmat package to run the code (http://www.gp-you.org). An Octave version will become available (also with CUDA support) in the near future. Also in near future a design algorithm for trans-Gaussian kriging will be available.
