Welcome to the Louisiana Virtual Coast Data Archive

ADCIRC bathymetry (in meters) for the SL15 grids along the northern Gulf of Mexico coast. In this image, the bathymetry is clipped at -100 meters for display purposes. Each of the SL15 grids, for the 2005, 2007, and 2010 simulation sets has details that are not discernable at this scale shown.The Louisiana Virtual Coast Data Archive is a joint program maintained by the Center for GeoInformatics and the Hurricane Center at Louisiana State University.

Here you will find resources developed and utilized by the Federal Emergency Management Agency (FEMA) and local governments for assessing flood risk across the Louisiana coastal zone.

The Louisiana Virtual Coast is a comprehensive digital data set that can be used to characterize and gain understanding about the dynamics of Louisiana's coastal landscape. The objective of the Virtual Coast Project is to compile relevant data sets of the highest quality, QA/QC and process data sets, and make these data sets available to the coastal restoration and protection community. This effort is designed primarily to assist the modeling community, including both risk and restoration modeling, by making available the most current and accurate data sets from which model grids can be created or updated. The value added by this effort, in comparison to a general data warehouse, is the quality and accuracy of the data sets that will be part of the Virtual Coast.

The data you find here are provided as is, and without warranty or support.

NEW DATA ADDED ON 10/29/2010

Introduction:


The data available in this archive constitute modeled output and research conclusions developed by the Federal Emergency Management Agency (FEMA) following the hurricanes Katrina and Rita disasters. The data include, but are not limited to, storm surge model output, wind surveys, and draft reports.  Some of the data were obtained as a result of a Freedom of Information Act (FOIA) request.

*Note:


The data maintained in the Cameron and Morgan City folders appear to be identical. A lack of documentation made it difficult to distinguish the folder's content.  Accordingly, the decision was made to maintain the folder structures as they were delivered. No modifications were made to the data.

About this site...


ADCIRC SL15 grid for the greater New Orleans AreaThis site was developed to provide archival services for the Louisiana Virtual Coast Project.   The data in this archive were collected and used by the Federal Emergency Management Agency (FEMA).  FEMA used this data to assess the impacts and risks of wind and flood for communities in coastal Louisiana. The data was provided by the LSU Hurricane Center, and is stored on servers maintained by the LSU Center for GeoInformatics.

The Center for GeoInformatics (C4G):


The Center for GeoInformatics is a research center of the Louisiana State University in the College of Engineering that focuses on ways science and technology can be used to address quantitative issues  geography, geosciences, and related branches of engineering.   The C4G facilities house the offices, classrooms and computer headquarters for GULFNet: a network of Global Positioning System (GPS) Continuously Operating Reference System (CORS) sites positioned throughout the State of Louisiana.

The Hurricane Center:


The LSU Hurricane Center is a research and service unit within Louisiana State University. It was established by the Board of Supervisors to act as a focal point to conduct research, transfer knowledge, and assist the state and nation in coping with hurricanes and their impacts, and it is a critical component of the new LSU initiative, Coastal Stainability Agenda. The goal of this initiative is to provide leadership in reducing risks in coastal landscapes by developing knowledge to provide sound comprehensive programs that balance public safety, economic development, emergency management and coastal restoration.

About the Virtual Coast:


The Louisiana Virtual Coast is a comprehensive digital data set that can be used to characterize and gain understanding about the dynamics of Louisiana's coastal landscape. The objective of the Virtual Coast Project is to compile relevant data sets of the highest quality, QA/QC and process data sets, and make these data sets available to the coastal restoration and protection community. This effort is designed primarily to assist the modeling community, including both risk and restoration modeling, by making available the most current and accurate data sets from which model grids can be created or updated. The value added by this effort, in comparison to a general data warehouse, is the quality and accuracy of the data sets that will be part of the Virtual Coast.
