The table below lists the feature classes available throught the USA WFS server at Atlas0. The feature classes originate from the USSampledata.mdb file provided by the Intergraph Corporation. Attribute data for this dataset has been updated to include Census statistics from the 2000 Census. Click features.xml to view the WFS features.xml file. The URL to access the USA WFS server is http://atlas0.lsu.edu/usa/request.asp.

The Louisiana ("LA") Server at http://atlas0.lsu.edu/la/request.asp
The table below lists the feature classes available throught the Louisiana WFS server at Atlas0. The feature classes originate from two sources: the Louisiana GIS CD version 2 (lagiscdv2) and the Atlas Indices (atlasquery). Click features.xml to view the WFS features.xml file.The URL to access the LA WFS server is http://atlas0.lsu.edu/la/request.asp.

Feature Class   Source   Description (see note below)
bathymetry   lagiscdv2   A linear dataset depicting the offshore bathymetry for Louisiana. The contour interval is 2 meters. These data were derived from point depths depicted on NOAA Navigation charts. The depths on the NOAA charts are typically relative to 'mean low Gulf' levels, so these depths are conservative.
coastalzone   lagiscdv2   A polygon dataset representing the extent of the LDNR regulatory area defined as the Louisiana Coastal Zone. This area comprises a band across the southern border of the state and ranges in width from approximately 30 miles at the west edge of the state to over 150 miles at the eastern and Mississippi River Delta areas of the state.
community   lagiscdv2   A subset of the complete GNIS data set for Louisiana. This subset only includes features identified as in the category of 'Community.' It includes features such as schools, churches, and hospitals.
cwcplan   lagiscdv2   A polygon dataset depicting the areas of coastal wetlands in the state of Louisiana. This area encloses the tidally influenced coastal region three feet or lower in elevation. This dataset was developed as part of the Louisiana Coastal Wetlands Conservation Plan funded by EPA.
ewocds   lagiscdv2   A point dataset representing the locations of Early Warning Organic Compound Detection System (EWOCDS) sites from the Louisiana Department of Environmental Quality.
facilities   lagiscdv2   A subset of the complete GNIS data set for Louisiana. This subset only includes features identified as in the category of 'Facilities.' This category includes infrastructure type constructions such as airports, bridges, dams, tunnels and mines.
hightide   lagiscdv2   A linear dataset representing the astronomical high tide line as compiled from National Wetlands Inventory (NWI) 1:24,000-scale habitat maps that were photo-interpreted from color-infrared aerial photography acquired between November 1988 and March 1989 at a scale of 1:65,000.
landwater   lagiscdv2   A polygon data set derived from TM imagery that indicates areas of land and areas of water in the Louisiana coastal zone.
parish250k   atlasquery   A polygon dataet representing the Louisiana parishes "land" boundaries as digitized from USGS 1:250,000 topographic quadrangles. The dataset includes hyperlinks to web pages on Atlas for searching for data corresponding to the parishes.
parishes   lagiscdv2   A polygon dataset representing 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 (1999) available representation of the parishes of Louisiana and as a consequence, the best currently available representation of the territorial bounds of the state.
places   lagiscdv2   A point dataset showing all populated places of Louisiana asidentified by the United States Census Bureau. The data attributes include city name, FIPS code, Census class, and selected demographic data.
powerlines   lagiscdv2   A linear data set for 'Powerlines' extracted from 1997 TIGER/Line source data. Power transmission lines have Census Feature Class Code (CFCC) C20, and include only high voltage electrical lines, on towers, situated on cleared right-of-way.
primaryroads   lagiscdv2   A linear dataset representing the state maintained primary and secondary road network of Louisiana. The dataset includes Interstates, US highways, and Louisiana State Highways.
q024k   atlasquery   A polygon dataet representing the USGS 1:24,000 tiling system for the 7.5' topographic quadrangles. The dataset includes hyperlinks to web pages on Atlas for searching for data corresponding to the quadrangles.
q100k   atlasquery   A polygon dataet representing the USGS 1:100,000 tiling system for the100K topographic quadrangles. The dataset includes hyperlinks to web pages on Atlas for searching for data corresponding to the quadrangles.
q250k   atlasquery   A polygon dataet representing the USGS 1:250,000 tiling system for the 250K topographic quadrangles. The dataset includes hyperlinks to web pages on Atlas for searching for data corresponding to the quadrangles.
qq024k   atlasquery   A polygon dataet representing the quarter quadrangles of the USGS 1:24,000 tiling system. The dataset includes hyperlinks to web pages on Atlas for searching for data corresponding to the quadrangles.
railroads   lagiscdv2   A linear data set for 'Railroads' of Louisiana extracted from 1997 TIGER/Line source data. Railroad Mainlines, Spurs, Yards, and specialized rail lines have Census Feature Class Codes (CFCC) of B01 - B52, although in this data set, only B01, B03, B11, B12, B13, B21, B23, and B50 codes are present.
refuges   lagiscdv2   A polygon dataset representing the boundaries of National Wildlife Refuges in southcentral United States. National Widlife Refuges are administered and owned by federal agencies.
soils   lagiscdv2   A polygon data set containing the United States Department of Agriculture and the Soil Conservation Service STATSGO soils map clipped to the State of Louisiana boundary.
subsegments   lagiscdv2   A polygon data set of the watershed basin subsegments for Louisiana from the Louisiana Department of Environmental Quailty.
water   lagiscdv2   A subset of the complete GNIS data set for Louisiana. This subset only includes features identified as in the category of 'Water.' This includes features such as lakes rivers, bays, and canals.
wf_manage   lagiscdv2   A polygon dataset representing the boundaries of Wildlife Management Areas in Louisiana. Wildlife Management Areas are administered by the states, but may be privately owned.

Note: The descriptions for the feature classes with a source of lagiscdv2 were taken from the metadata of these feature classes as supplied on the original Louisiana GIS CD version 2.
