Public reference dataset
Hi Christoph, I have prepared few datasets of interest for testing geostatistical algorithms: http://spatial-analyst.net/book/data-sets I personally like the BCI (soil samples) dataset very much (used in the spatstat package also). It has enough points and they are sampled at both short and regular distances (see http://spatial-analyst.net/wiki/index.php?title=Image:Fig_pH_RK_draped.jpg). Here are some examples: http://spatial-analyst.net/wiki/index.php?title=Spatial_interpolation_exercises_(NL)#Spatial_prediction_of_soil_properties_for_the_Barro_Colorado_Island_50_ha_Plot Additional grids for BCI are available here: http://spatial-analyst.net/book/BCI_grids The field data collection and lab analysis has been explained in detail here: https://ctfs.arnarb.harvard.edu/webatlas/datasets/bci/soilmaps/BCIsoil.html Then, there are also various datasets used in the geostats books: Diggle, P.J., Ribeiro Jr, P.J., 2006. Model-based Geostatistics. Springer Series in Statistics, 230 p. http://www.leg.ufpr.br/mbgbook/ Reimann, C., Filzmoser, P., Garrett, R., Dutter, R., 2008.

However, I was just wondering if their is a "standard reference" dataset for block kriging. Anyway, thanks for your comment. Christoph Am 03.03.2010 um 15:14 schrieb edzer pebesma:

to test some software for block kriging. I appreciate any hint.
