Channel Portfolio Tool (CPT)

CPT is designed to enable analysis of commercial utilization of the Corps-maintained waterway infrastructure at a variety of coverage levels. At the most detailed level, individual channel sub-reaches may be chosen for analysis and compared to other sub-reaches in the USACE portfolio of navigation projects. However, in order to provide decision support to personnel at all levels of Corps management, CPT can also be used to analyze and compare commercial usage figures at the Project, District, and Division levels. For example, a District program manager might want to see which navigation project under his or her control handles the most exports of a particular commodity. CPT pulls from a large database that is maintained by the Corps’ Waterborne Commerce Statistics Center (WCSC).

Setting the desired level of analysis is done through the CPT Home screen:

CPT Lite

CPT Lite provides Project-level coverage of waterborne commerce movements through Corps navigation channels, ports, and waterways.  CPT Lite is designed for decision makers requiring quick, reliable access to summary statistics for Corps navigation projects.  Supporting figures are provided by the Waterborne Commerce Statistics Center (WCSC) through the Navigation Data Center (NDC), and users are advised to validate the results of CPT Lite against the official NDC reports for decision-support purposes.

CPT Lite is presently only available to US Army Corps of Engineers employees. To obtain username and password information or provision your iOS device, please contact and state your need.
