Maps

USGS programs produce a wide variety of maps, geonarratives and tools that place our data and information within a geospatial context. This collection features mapping products and tools related to hurricanes and the science we conduct to better understand and respond to them.

Land area change in coastal Louisiana (1932 to 2016)

Coastal Louisiana wetlands are one of the most critically threatened environments in the United States. These wetlands are in peril because Louisiana currently experiences greater coastal wetland loss than all other States in the contiguous United States combined. The analyses of landscape change presented here have utilized historical surveys, aerial, and satellite data to quantify...

Land area change analysis following hurricane impacts in Delacroix, Louisiana, 2004--2009

The purpose of this project is to provide improved estimates of Louisiana wetland land loss due to hurricane impacts between 2004 and 2009 based upon a change detection mapping analysis that incorporates pre- and post-landfall (Hurricanes Katrina, Rita, Gustav, and Ike) fractional water classification of a combination of high resolution (QuickBird, IKONOS and Geoeye-1) and medium...

Land area change and fractional water maps in the Chenier Plain, Louisiana, following Hurricane Rita (2005)

In this study, we estimated the changes in land and water coverage of a 1,961-square-kilometer (km2) area in Louisiana's Chenier Plain. The study area is roughly centered on the Sabine National Wildlife Refuge, which was impacted by Hurricane Rita on September 24, 2005. The objective of this study is twofold: (1) to provide pre- and post-Hurricane Rita moderate-resolution (30-meter (m))...

Land Area Change and Overview of Major Hurricane Impacts in Coastal Louisiana, 2004-08

The U.S. Geological Survey (USGS) assessed changes in land and water coverage in coastal Louisiana within 2 months of Hurricane Gustav (September 1, 2008) and Hurricane Ike (September 13, 2008) by using Landsat Thematic Mapper (TM) satellite imagery. The purpose of this study was twofold: (1) to provide preliminary information on land-water area changes in coastal Louisiana shortly after...
