NOAA Simplifies Nautical Chart Error Reporting

NOAA Simplifies Nautical Chart Error Reporting

NOAA has released ASSIST, a system for submitting questions and reporting nautical chart errors to NOAA's Office of Coast Survey. ASSIST has a mobile-friendly design and improved user interface that allows customers to access the system conveniently from any device. The tool replaces Coast Survey's Inquiry and Discrepancy Management System (IDMS), a database that collected nearly 20,000 comments, inquiries, and discrepancy reports since 2008.

ASSIST offers new features including the ability to:

  • Tag your submission on a NOAA chart, map, or satellite image
  • Enter reports from a mobile device
  • Comment or report an error using a single form


These improvements streamline the internal Coast Survey workflow, allowing faster, more efficient responses to customers.
