Current Activities
The Mississippi Valley Division primary 2007 goal is establishing a
5-year IENC Chart Maintenance contract. In 2005 and 2006 testing and
development of procedures for providing monthly IENC products
updates was completed. Our objective was to apply USCG Local Notice
to Mariner chart corrections within a monthly IENC update cycle. The
update cycle would also integrate new source data as applicable.
This pilot project provided needed information to formalize this
process. Therefore, USACE is now proceeding with solicitation and
award of a IENC Chart Maintenance contract to provide these
services.
Other IENC Projects
We have developed the concept of a "Mini-IENC" which in generic terms means a large mapping scale,
limited geographic extent S-57 cell. Production tools are being finalized to create Mini-IENCs for the
Mississippi River Southwest Pass and the Mississippi River crossings. These Mini-IENCs will capture
the highly variable shoaling and scour areas that impact river navigation.
Mini-IENCs may be published as often as daily, if user demand for the product supports this frequency.
