Description:
Abstract:
This data set consists of the 1km cell grid for the Louisiana Coastal Area. The LCA project area was divided into a grid consisting of 43,138 one square kilometer polygons to function as a basic input unit for the LCA desktop model. The grid was generated using ESRI ArcInfo GIS software.
Purpose:
To allow for exchange and integration of spatial and non-spatial information in the LCA desktop model at different scales.

Access_Constraints:
It is strongly recommended that these data are directly acquired from the distributor described in the distribution section of this metadata record or from another USGS server and not indirectly through other sources which may have changed the data in some way. The distributor makes no claim as to the data's suitability for other purposes.
Use_Constraints:
Acknowledgement of the US Geological Survey, National Wetlands Research Center, Coastal Restoration Field Station as a data source would be appreciated in products developed from these data, and such acknowledgement as is standard for citation and legal practices for data sources is expected by users of these data. 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 these data, based on the description of appropriate/inappropriate uses in this metadata record. These data are not legal documents and are not to be used as such.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The accuracy of the attributes (mostly geographic) are generated through GIS software. Exact accuracy is dependent on the software.
Logical_Consistency_Report:
Data are inherently polygonal. Segments making up the outer and inner boundaries of a polygon tie end-to-end to completely close the area. No duplicate features exist.
Completeness_Report:
The data are complete as possible. There are no known ommissions.
