[R-sig-Geo] Public reference dataset

[Tomislav Hengl]

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:

The field data collection and lab analysis has been explained in detail here:

Then, there are also various datasets used in the geostats books:
