ACD_methods

Code and documentation to perform automated change detection methods using Google Earth Engine.

Early version

This early version repository currently has Earth Engine JavaScript files for:

  • Performing automated change detection following the general approach used to update the National Land Cover Dataset
  • Performing automated change detection using iteratively reweighted multivariate alteration detection (IW-MAD), as described by Nielsen, A.A. 2007
  • Masking clouds from Sentinel 2 images.
  • Calculating and appending shape metrics to polygon attributes.

Usage

Currently, script provided in the EE folder will need to be loaded into and run in Google Earth Engine code editor.

To see an example of an analysis using these methods, see our case study detecting energy development in the range of the Lesser prairie chicken.

For detailed explanation of methodlology, see our vignette
