The Inland Electronic Navigation Charts (IENC) are digital charts referred to as “cells”. The cells are updated on a monthly basis to allow the general public to stay up-to-date. There are RSS feeds set up for each of the cells. The USACE does not require anyone to create a Login to download IENC data, but we do ask for some basic information from the requestor to be used for statistical purposes. The cells are currently available in three different formats, linked below:
