On this Picostat.com statistics page, you will find information about the topo data set which pertains to Spatial Topographic Data. The topo data set is found in the MASS R package. Try to load the topo data set in R by issuing the following command at the console data("topo"). This may load the data into a variable called topo. If R says the topo data set is not found, you can try installing the package by issuing this command install.packages("MASS") and then attempt to reload the data with library("MASS") followed by data("topo"). Perhaps strangley, if R gives you no output after entering a command, it means the command succeeded. If it succeeded you can see the data by typing topo at the command-line which should display the entire dataset.
If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the topo R data set. The size of this file is about 618 bytes.
