Coastal Louisiana Resource Information System

Vector Shorelines  These vectorized shorelines document the historical rate and range of Louisiana Gulf shoreline change for the period from 1855 to 2005. They provide a comprehensive quantification of shoreline evolution trends along Louisiana’s Gulf shoreline and establish a baseline dataset for future restoration efforts, define the character and patterns of historical shoreline change, and quantify the rates of linear shoreline retreat.

 

Land Cover  These land cover data sets document how much of Louisiana's coasta region is covered by forests, wetlands, impervious surfaces, agriculture, and other land and water types. By comparing these land cover data sets over a period of time, users can also document land use trends and changes.

 

Imagery  Remote sensing technologies are usually the most cost-effective means of getting information for areas that are inaccessible, far away, difficult to traverse, require a broad view, or are too large to effectively manage or assess with traditional surveying methods.

 

T-Sheets  These are a series of maps of the Louisiana coast between the years 1855-1948 created by the United States Coast Survey. These T-sheets provide an invaluable look at the shoreline condition over a century ago and serve as a starting point for analyzing shoreline change. These scans were produced by NOS, and provided by NOAA Coastal Services Center.
