The latest geometric revision to the Parish Boundaries was made 8/2/2012.All revisions are described below under "Credits".Louisiana Parish Boundaries approved by Resolution of the GIS Council on January 19, 2000. This is a region dataset depicting the polygon boundaries of the 64 parishes comprising the state of Louisiana. Parish boundaries extend 3 miles out into the Gulf of Mexico from the coastline. This dataset was derived from many data sources and conveys the best currently (2005) available representation of the parishes of Louisiana and as a consequence, the best currently available representation of the territorial bounds of the state.

This data set contains boundaries for parishes in coastal Louisiana. Vector polygons in this data set represent parish management areas. Location-specific type and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Louisi...

USGS and FEMA collaborated to collect data on residences in six of the twenty disaster-declared parishes in Louisiana during the August 8–11 floods in 2016. The National Map Corps (TNMCorps), a volunteer program run the National Geospatial Program of the U.S. Geological Survey, were invited to help with this task. From August 30 to September 30, 2016, Corps editors created and classified data points for each building within the six parishes. FEMA used this information to find which buildings in the parishes were residences, and to estimate by how many feet underwater the houses were. This data was then used to help determine the amount of assistance provided to homeowners in these parishes.The data points were summarized into 5 km hexagons (a process called hexbinning) to provide an easier visualization of the number of points collected by TNMCorps. Lighter colors indicate more buildings per hexagon. Per-hexagon numbers range from 1 to 1800.Map also includes flood extent estimates from FEMA and GOSEP (Louisiana Governer's Office of Homeland Security & Emergency Management). Parish outlines derived from U.S. Census TIGER data.

The NOAA Coastal Change Analysis Program (C-CAP) produces national standardized land cover and change products for the coastal regions of the U.S. C-CAP products inventory coastal intertidal areas, wetlands, and adjacent uplands with the goal of monitoring changes in these habitats through time. The timeframe for this metadata is summer 2016. These maps are developed utilizing high resolution a...

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the Alabama West (FIPS 2703) State Plane projection and coordiante system The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000.

The Barrier Island Comprehensive Monitoring (BICM) program was developed by Louisiana’s Coastal Protection and Restoration Authority (CPRA) and is implemented as a component of the System Wide Assessment and Monitoring Program (SWAMP). The program uses both historical data and contemporary data collections to assess and monitor changes in the aerial and subaqueous extent of islands, habitat types, sediment texture and geotechnical properties, environmental processes, and vegetation composition. Examples of BICM datasets include still and video aerial photography for documenting shoreline changes, shoreline positions, habitat mapping, land change analyses, light detection and ranging (lidar) surveys for topographic elevations, single-beam and swath bathymetry, and sediment grab samples. For more information about the BICM program, see Kindinger and others (2013). The U.S. Geological Survey, Wetland and Aquatic Research Center provides support to the BICM program through the development of habitat map products using aerial imagery and lidar elevation data and assessing change in habitats over time. These data provide a snapshot of barrier island habitats and can be combined with other past and/or future maps to monitor these valuable natural resources over time. The current effort of this habitat mapping program includes developing habitat maps for 2008 and 2015-2016 for the following BICM regions: 1) West Chenier; 2) East Chenier; 3) Acadiana Bays (only Marsh Island); 4) Early Lafourche Delta; 5) Late Lafourche Delta; 6) Modern Delta (only Chaland Headland and Shell Island); and 7) Chandeleur Islands. Additionally, a habitat change analysis will be conducted comparing reaches mapped in 2008 and 2015-2016. The BICM program has developed two habitat classification schemes which include a detailed 15-class habitat scheme and a general eight-class habitat scheme. The detailed scheme was developed specifically for this habitat mapping effort and builds off the general scheme used in previous BICM habitat mapping efforts (Fearnley and others, 2009). The additional classes developed in the detailed scheme are primarily used to further delineate various dune habitats, separate marsh and mangrove, and distinguish between beach and unvegetated barrier flat habitats. To ensure comparability between this effort and previous BICM map products, we have crosswalked the detailed classes to general habitat classes previously used by Fearnley and others (2009).
