Description:
This data set contains sensitive biological resource data for waterfowl species in coastal Louisiana. Vector polygons in this data represent waterfowl habitats with density values by habitat zone and watershed or by survey zone. Species-specific abundance, seasonality, status, life history, 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 Gulf-Wide Information System (G-WIS) database for the entire coastal zone of Louisiana. The G-WIS data include three main components: shoreline habitats, sensitive biological resources, and human-use resources. The Louisiana G-WIS biological data layers are primarily based on quantitative LDWF survey data collected over the last decade through 1999 or 2000. Species abundance and concentration attributes associated with the spatial data are quantitatively expressed as mean densities or counts and/or as categorical descriptive values (high, medium, or low population densities). See also the NESTS, SH_BIRD, and NHP data layers, part of the larger Louisiana G-WIS database, for additional bird information.

The source dataset was derived from sources including USGS quads, aerial photography, highway plans, DOTD's control section road network and existing general highway maps. The source data set originated in 1983-1985 by digitizing 7.5' USGS quads on high precision input tables, but is updated regularly at LDOTD using the other sources mentioned above.

Description:
This data set contains arcs representing the Environmental Sensitivity Index (ESI) classification of the outer coast of Louisiana. The ESI is a classification and ranking system, which characterizes the relative sensitivity and ease of cleanup of shoreline habitats exposed to spilled oil. This data set comprises a portion of the Gulf-Wide Information System (G-WIS) database for the entire coastal zone of Louisiana. The G-WIS data include three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the HABITAT and ESIP data layers, part of the larger Louisiana G-WIS database, for additional habitat and ESI information.
