Louisiana Gulf-Wide Information System Data

Environmental Sensitivity Index (ESI), Biology, and Socio-economic Components

=============================================================================

Geospatial data and relational data tables representing the environmental sensitivity index (ESI), biology, and socio-economic components of the Louisiana Gulf-Wide Information System (G-WIS).  Note that these data are delivered in Geographic coordinates (NAD83).  The conversion of the spatial data layers from the original UTM working projection to the Geographic coordinate system resulted in a small decrease in precision, and necessitated small changes in some coverages and relational data tables to maintain topological and data integrity.

 

Data Descriptions:

 

Environmental Sensitivity Index (ESI) and base layer coverages

 

esi - spatial data layer containing arcs ranked according to Environmental Sensitivity Index guidelines (only outer coast)

esip - spatial data layer containing polygons ranked according to Environmental Sensitivity Index guidelines (compressed)

hydro - spatial data layer containing hydrography (compressed)

index - spatial data layer containing index

 

Biology coverages and relational data tables

 

activity - data table containing activity/life-history information for biological resources

bear - spatial data layer containing biological resources for Louisiana black bear

biores - data table containing species, seasonality, concentration, and source information for biological resources

breed - data table containing life-history information for biological resources

crawfish - spatial data layer containing biological resources for crawfish and river shrimp

freshwater_fish - spatial data layer containing biological resources for freshwater (inland) fish

gator - spatial data layer containing biological resources for alligators

habitats (salinity, brackish marsh, intermediate marsh, salt marsh, fresh marsh, scrub shrub, seagrass, swamp)  - spatial data containing coastal habitats

nests - spatial data layer containing biological resources for waterbird colonies

nhp - spatial data layer containing biological resources from the Natural Heritage Program database (rare and endangered species)
