Topographic Change Detection

Download the Feshie Data
Create a GCD Project:
1. 1. Different years loaded as surveys and do error modelling
  2. A change detection (threshold @ 80% probability) for two of the epochs
  3. A budget segregation with at least two examples each of the following mechanisms of change identified:
    1. Bank Erosion
    2. Channel Bed Lowering (degradation / incision)
    3. Channel Bed Rising (aggradation)
    4. Bar Development

The work we will do on “budget segregation” is based on Wheaton et al. (2013):

Wheaton JM, Brasington J, Darby SE, Sear DA, Vericat D‡., and Kasprak A. 2013. Morphodynamic signatures of braiding mechanisms as expressed through change in sediment storage in a gravel-bed river. Journal of Geophysical Research - Earth Surface. DOI: 10.1002/jgrf.20060.

Analysis

The tabular results by category is showing you the same data of all the graphs from the end of the Change Detection Visual Video from the budget segregation. All the percent of the area of Interest with detectable change are close to 90% which Is quite high. The table also allows you to see how much total area of rising or lowering occurred in meters squared.
