Training: Applied Spatial Statistics Using R and ArcGIS

Eria Consulant

Dr. Michael Tuffly

SoCal URISA training: January 25, 2020, at Rio Hondo Community College, Whittier, CA

This one-day (8 hour) course is a hands-on applied workshop designed to teach people how to correctly apply spatial statistics to spatial data. We will be using the statistical program “R” coupled with ArcGIS.

Topics that will be covered are:

  • Programming in “R”
  • Linear Regression
  • Spatial Weight Matrix creation
  • Moran’s I
  • General Least Squares (GLS)
  • Variograms
  • Covariance functions
  • Spatial-temporal analysis

At the end of the workshop attendees’ will be able to:

  • 1) create a basic program in “R”
  • 2) assess and evaluate spatially correlated data
  • 3) adjust statistical models for spatial autocorrelation.

This course is designed for beginners to experts. It would be extremely helpful to have a basic understanding of statistics, ArcGIS, and some exposure to computer programming. As with most workshops, the more one knows to go into the course the more you will take home. This will be an all-day workshop with breaksBenefits:
If desired, participants will be able to get GIS Professional (GISP) educational credits.  These educational credits can be applied for the GISP certificate or for recertification credits (  This course also can be used for continuing education credits (CE) for the American Society for Photogrammetry and Remote Sensing (ASPRS) Certified Mapping Scientist (CMS) certification (   Also, this course can be used for Certified Forester Education (CFE’s) from the Society of American Foresters (


A willingness to learn.  As with most workshops the more one knows going into the course the more you will take home.  It is required that attendees have knowledge of basic statistics, fundamental knowledge of R, and basic computer programing skills.

All the material including data, R-libraries, R-scripts, and manuals will be loaded onto Flash Drives for the students.

Instructional Theme:
Most examples and exercises in this workshop are environmentally based.  That is, exercises primarily use publicly available data from government agencies such as:  USGS, EPA, USFS, and BLM.
