• 12 Jan: USGS fact sheet on UTM coordinates
• 12 Jan: Simple Random Sample from Frerichs, Rapid Surveys. Pages 3-1 to 3-15 cover what I discussed today.
• 23 Jan: Schabenberger and Gotway, Statistical Methods for Spatial Data Analysis (on reserve in Parks library) has all the details and many derivations of results presented in class. I'll refer to that as S&G from now on.
  Sections 5.1-5.3 discuss simple, ordinary, and universal kriging.
• 30 Jan: S&G, Chapter 4 has all the details and more on estimating covariance and semivariance functions.
• 7 Feb: Example of badly behaved Gaussian kriging from Wackernagel 2003, Multivariate Geostatistics.
• 16 Feb: Most of my material on spatial sampling was based on Chapter 6 of Webster and Oliver, 2009, Geostatistics for Environmental Scientists, 2nd ed. It's on reserve for this course in Parks Library
  Some came from Oliver (ed.) 2010, Geostatistical Applications for Precision Agriculture, and Lake, Bock, and Goode (ed.) 1997, Precision Agriculture: Spatial and Temporal Variability of Environmental Quality.
