Description:

Abstract:

This data set consists of the 1988 National Wetlands Research Center Habitat vector data that has been converted to a rasterized version. The original Arc/Info vector data were developed by photointerpreting 1988 color infrared aerial photography (scale 1:63000), digitizing the maps and incorporating the digital data into a geographic information systems (GIS). The vector data (343 7.5' quadrangles) were then converted to raster to allow for all the quadrangles to be merged into one data set. The original attributes were aggregated into 19 Level One landcover categories that were developed by NWRC; this new classification of the Classification of Wetlands and Deep-Water Habitats of the United States (Cowardian, et al. 1979) simplifies the 800+ classes for interpretation.

Purpose:

To provide a general landcover classification for interpretation on projects not requiring an intense level of detail.

Any downloading and use of these data signifies a user's agreement to comprehension and compliance of the NWRC Standard Disclaimer. Insure all portions of metadata are read and clearly understood before using these data in order to protect both user and NWRC interests. See section 6.3 Distribution Liability.

Use_Constraints:

Acknowledgement of the National Wetlands Research Center 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 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 of that comparisons with other data sets for the same area from other time periods may be inaccurate due to inconsistencies resulting from changes in photo interpretation, mapping conventions, and digital processes over time. These data are not legal documents and are not to be used as such.

Horizontal_Positional_Accuracy_Report:

The accuracy of the horizontal positions are based on the accuracy of the original data source. The 1:100000 quadrangles have a minumum resolution of 25 meters prior to the rasterization process.

Process_Step:

Process_Description:

The individual 7.5' quadrangles were merged into the 1:100,000 groupings to assist in the aggregation of the Cowardian classification. A coding scheme was developed to aggregate the 800+ Cowardian classes into a manageable grouping of 157 land cover classes. The 157 classes were then reaggregated into 19 Level One categories. The 1:100000 groupings were then rasterized and converted to an ERDAS format. The data were then merged into one coastal Louisiana data set. To perform coastwide and basin landcover and wetland trend analyses, the 1988 data set were clipped to the extent of the 1978 Level One habitat data set.
