1999 Atchafalaya Basin Mapping Project
The Atchafalaya River is the largest of all distributaries of the Mississippi River,
with a basin covering more than one million acres. The New Orleans District Corps of Engineers
completed the 1999 Atchafalaya Basin Mapping Project, which has resulted in the creation of an
overall Atchafalaya Basin GIS as well as four cartographic products totaling nearly 750 map sheets.
The GIS has been developed utilizing the Regional Engineering and Environmental Geospatial
Information System (REEGIS). The REEGIS schema was developed by the Corps of Engineers Mississippi
Valley Division, and was implemented for the Atchafalaya Basin using Intergraph’s MGE software
and an Oracle database. The GIS encompasses such categories as general river features,
hydrography, navigation aids and facilities, structures, transportation, and other data features.
Atchafalaya River Hydrographic Survey Book
The Atchafalaya River Hydrographic Survey Book consists of 137 map sheets mapped to 1:10,000 publication scale. Each map sheet is available for download in Adobe PDF format (in the same plot scale as the paper maps) and MicroStation DGN format.
Atchafalaya River Navigation Book
The Atchafalaya River Navigation Book consists of 40 map sheets mapped to 1:24,000 publication scale. Each map sheet is available for download in Adobe PDF format (in the same plot scale as the paper maps).
