This software is documented in the Journal of Structural Geology article: “Fold Geometry Toolbox – Automated determination of fold shape, shortening, and material properties” by Marta Adamuszek, Daniel Walter Schmid, and Marcin Dabrowski.
FGT is a program to analyze fold geometry in 2D. This toolbox estimates the amount of shortening and mechanical properties of folds using four parameters: arc length, amplitude, wavelength, and thickness. FGT is capable of dealing with noisy interfaces and complex fold geometries.
The toolbox can be download from here. A new version of FGT will be available on 1.06.2022 !!!
