Coastal Wetlands Planning, Protection and Restoration Act Habitat Data
Entry ID: usgs_nwrc_cwphab

[ Update this Record ]

Summary
Abstract: The Louisiana State Legislature created CWPPRA in order to conserve, restore,
create, and enhance Louisiana's coastal wetlands. The restoration plans
developed persuant to these acts specifically require an evaluation of the
effectiveness of each coastal wetlands restoration project in achieving
long-term solutions to arresting coastal wetland loss. These data sets consist
of digital data describing wetland and upland habitats within the various
The Coastal Wetlands Planning, Protection and Restoration Act Habitat Data
project boundaries for various years according to available funding. The data
set includes maps that were digitized at the Mid-Continent Ecological
Center from hard copies developed at the U.S. Geological Survey, National
Wetlands Research Center. The habitat data were derived from interpretation of
color infrared photography flown at various scales depending on project area
size: Project areas less than 200 acres are flown at 1:6,000, areas of 200 to
20,000 acres at 1:12,000, and areas greater than 20,000 acres at 1:24,000.
Wetlands were classified on the maps using the Cowardin, et al., classification
scheme, to the level of salinity modifiers. Uplands were classified using the
Anderson, et al., classification scheme.

The intended use of this data set is to provide information to aid efforts in
the conservation, restoration, creation, and enhancement of Louisiana's coastal
wetlands in order to aid in long-term solutions to these problems.

Quality
Interpreted photos were quality checked by two photo interpreters for attribute
classification. Field verification was performed for areas where attribute
classification was questionable; local personnel with state and federal
agencies assisted in field identification. The mylar-based maps were quality
checked by cartographic personnel for line and labelworks and any problems were
corrected. The attribute accuracy is tested manually comparing hard copy plots
of the digital data with the source materials. When attributes cannot be
visually verified on plots they are interactively queried and verified on
screen. In addition, the attributes are compared against a master set of valid
attributes.

ARC/INFO software is used to create and maintain topological relationships
between features. There are no duplicate features, but coincident lines are
maintained between data layers when appropriate. Polygonal features begin and
end at the same point, contain no overshoots or undershoots, and contain a
single label. Linear features are continuous where appropriate, i.e., dangling
arcs are removed if they are not required.

For cartographic process, accordance with nationally accepted mapping standards
and conventions were followed.

The horizontal positional accuracy is tested by visual comparison of hard copy
check plots to the source materials and verifying the location of the data
on-screen relative to other data layers in the same geographic area.


Access Constraints
It is strongly recommended that this data is directly acquired from the
distributor described above or from another USGS Biological Resources Division
server and not indirectly through other sources which may have changed the data
in some way. The distributor makes no claims as to the data's suitability for
other purposes.


Use Constraints
Acknowledgement of the U.S. Geological Survey, National Wetlands Research
Center as a data source would be appreciated in products developed from these
data, and such acknowledgment as is standard for citation and legal practices
for data source is expected by users of this data. Sharing new data layers
developed directly from these data would also be appreciated by NWRC staff.
Users should be aware that comparison with other data sets for the same area
from other time periods may be inaccurate due to inconsistencies resulting from
changes in mapping conventions, data collection, and computer processes over
time. The distributor shall not be liable for improper or incorrect use of this
data, based on the description of appropriate/inappropriate uses described in
this metadata document. These data are not legal documents and are not to be
used as such.
