Sponsored by:
H. GETTING TO KNOW GCD 6 SOFTWARE
WORKSHOP PLAN – DAY 1… (AFTERNOON)
E. Essential Best Practices to Support GCD
F. Traditional Approaches to Change Detection
G. Change Detection in Raster Calculator vs. GCD
H. Getting to know GCD Software
I. Thresholding Alternatives
J. Recap & Preview of Day 2
1:00 to 1:45
A Plan.. Not a Contract
1:45 to 2:15
2:15 to 3:00
3:15 to 4:00
4:00 to 4:45
4:45 to 5:00
3:00 to 3:15 BREAK
DOD 3
• Matlab, Wizard Based• Easy to modify code• Don’t need to know how
to code to use…• Poor Map Visualization• ASCII grids
GCD 4
• ArcGIS Plugins (9 & 10)
• Stand Alone Version• Big Effort was on
Underlying C++ Library
• Can be ported into stand-alone apps, web apps, or Arc plugins
GCD 5.2.0
• More focus on User Interface
• Flexible Analyses
• Extended Functionality
• More Interactivity w/ Analysis
THIS ANALYSIS USED TO BE CUMBERSOME• GCD 5 made it easier to:
– Robustly estimate errors in DEMs
– Determine significance of uncertainty on DoD & Sediment Budget
– Calculate change in storage sediment budgets (with +/- vol.)
– Quantitatively interpret and spatially segregate budget

GCD 6
• New Project Explorer
• Major Back End Improvements
• Cleaner, more logical UI
• Portable Projects• Easier Map Interface• Automatic Reporting• Add-In
