Abstract

Using CAD & GIS to Develop USACE's National Channel Framework
Track: Transportation
Author(s): Greg Dreaper, Duane Morrision

The United States Army Corps of Engineers (USACE) and the National Oceanic and Atmospheric Administration (NOAA) are responsible for providing navigation information to the maritime community.

The national channel framework (NCF) is the basis for portraying information about congressional authorized navigation channels. The most fundamental components of the NCF consist of the outside channel limits, TOELINES, construction centerlines, top of slope lines, TOSLINES and quartered sections of the channel as well as reaches locations within the channels.

Up until recently, both agencies have been using CAD to build and maintain all channel framework data, creating design standards for the existing CAD products and transferring that data to the Mobile District eCoastal Enterprise GIS geodatabase. Through Internet Map Service (IMS) and Web Map services (WMS), the USACE is able to consolidate the channel framework data, and has been successful in sharing data with NOAA.
