386T: Methods to Simulate Land Change
How do we support transformation?
Professor Pontius (www.clarku.edu/~rpontius) offers an afternoon workshop of lecture and discussion concerning how to simulate land change. The workshop shows how to separate change into two components: quantity and allocation. We examine methods to measure the validity of the simulation by using five metrics: Misses, Hits, Wrong Hits, False Alarms and Correct Rejections. Participants learn how to compute and to interpret validation methods such as the Figure of Merit and the Total Operating Characteristic. Pontius shows also how to avoid common blunders when simulating and validating land change. Participants range from students to senior scientists. Participation in the morning workshop is not a prerequisite for the afternoon workshop. The workshop focuses on concepts, not on how to use specific software. Computers are not necessary for the workshop, although the methods are available in R and TerrSet. Participants receive a 50% discount on a general, academic, or student license of the GIS software TerrSet (www.clarklabs.org).
