GCD 3.0 Beta / DoD3- DEM of Difference Uncertainty Analysis Software
What Does it Do?
The DoD3 software was developed
primarily for morphological sediment budgeting in rivers. The volumetric change
in storage is calculated from the difference in surface elevations from digital
elevation models (DEMs) derived from repeat topographic surveys. As each DEM
has an uncertain surface representation (which might vary in space and time),
DoD3 provides a suite of tools for quantifying those uncertainties and propagating
them through to the DEM of difference. The program also provides ways for
segregating the best estimates change spatially using different types of masks.
The overall suite of tools is more generically applicable to many different
spatial change detection problems.Need Help?
Thank you for downloading our DoD
3.0 Beta Software. This release was made available to accompany a paper
published in Earth Surface Processes and Landforms. It is a fully functioning
Matlab version of the code, which was used in the ESPL paper (Wheaton et al., 2010a), the Wheaton (2008)
thesis, and the Wheaton et al. (2010b)
RRA paper. This code is provided as supplemental information with the ESPL
paper so that readers can test or extend the code as they see fit for their
purposes. The Maltab code was originally developed by Joe Wheaton and James Brasington.
DoD Software for latest developments (e.g. GCD 4.0). Due to confusion over DoD (see below) with Department of Defense, we have chagned the acronym to GCD (Geomorphic Change Detection) and renamed the software to GCD.
Note:DoD is an acronym for DEM (digital
elevation model) of Difference (not Department of Defense). DoDs are
derived from repeat topographic surveys and used in change detection
studies and morphological sediment budgeting.
