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. |
