Extending GCD Software

The GCD Software (formerly known as DoD Uncertainty Analysis Software) was originally produced as a Matlab code (DoD 3.0). In 2010, the software was refactored and extended as an open-source C++ library, which became the backbone to three user-interface versions of GCD 4.0: 1) a stand-alone windows application, 2) an ArcGIS 10 plugin, and 3) an ArcGIS 9.3.X plugin. Before GCD 4.0 was even officially released, we began work and planning on GCD 5.x. Funding has been provided by the USGS GCMRC and we have partnered with ESSA Technologies (the developers of the River Bathymetry Toolkit) to build GCD 5.

The primary improvements we are working on in GCD 5 include:
  1. Point Cloud Inputs
  2. Batch Processing Capabilities
    1. Temporal Batch Processing (for dealing with multiple years of survey data)
    2. Scenario Batch Processing (e.g. for sensitivity analyses)
  3. Expanded Data Formats - to allow file geodatabases as inputs and outputs
  4. Multiple Survey Methods
  5. Elevation Change Distribution Explorer
  6. Expanded FIS Default Libraries -  to include traditional airborne-LiDaR, narrow-beam green-LiDaR, ground-based LiDaR, single-beam SONaR, and multi-beam SONaR.
  7. Fixing known bugs from GCD 4
  8. Completing Development on 'grayed out' features in GCD 4
These developments should be released early summer 2012.


Funding is being provided by the USGS Grand Canyon Monitoring and Research Center
