Funding for these tools was provided by the Bonneville Power Administration (BPA Proposal # 2011-006-00 & BPA Project: 2003-017-00) and NOAA as part of the Columbia Habitat Monitoring Program (CHaMP).
The original concept for the CHaMP Topo Processing Tools was conceived by Joe Wheaton (Utah State University, Carol Volk and Kelly Whitehead (both from South Fork Research). The topo processing workflow was designed by this group and originally implemented in 2011 as a collection of Python scripts. In 2012, the tools were converted to an ArcGIS pluggin developed by Philip Bailey from North Arrow Research, collaborating with ESSA Technologies.
Some of the ArcGIS pluggin tools use features from the River Bathymetry Toolkit designed and developed by Philip Bailey and Nick Ochoski and Frank Poulsen at ESSA. The RBT was originally conceived by Philip and Jim Mckean of the US Forest Serice Rocky Mountain Research Station.
Total Station File Processing tools were developed by James Hensleigh, with input from Kenny DeMeurichy, at Utah State University.
