GCD Provides three primary ways for you to threshold data (all using exclusion): Simple Minimum Level of DetectionIn this video tutorial we explain how to use the GCDChange Detection panel to to a basic DoD Analysis with simple minimum level of detection thresholding. This is the equivalent of the raster calculator operation in the 03. Simple DoD in Raster Calculator tutorial.Propagated ErrorsIn this video tutorial we explain how to use the GCD ProbabilityIn this video tutorial we explain how to use the GCDChange Detection
panel to to a DoD Analysis with probabilistic
thresholding based on a confidence interval.This tutorial corresponds with topic G. Thresholding Alternatives in the GCD Workshop. See the lecture materials there for more background on the underlying theories for these methods. Extra: How to Make your own Elevation Change Distribtuions |
