United States Geological Survey, Biological Resources Division's, National Wetlands Research Center 19980512 vector digital data parishes_USGS_1998 http://www.usgs.gov/ This data set contains vector line map information. The vector data contain selected base categories of geographic features, and characteristics of these features, in digital form. The information was collected by digitizing Digital Raster Graphic Maps (DRGs) of 7.5 Minute Topographic Quadrangles and Louisiana territorial waters from the Louisiana Oil Spill Contingency Plan Map CD to create a digitized overlay of Louisiana highlighting the political boundaries for all parishes.

Lafayette Louisiana 70506 (337) 266-8543 (337) 266-8616 steve_hartley@usgs.gov The National Wetlands Research Center acknowledges the use of USGS Topographic Quadrangles for the state of Louisiana for the creation of the political boundaries. ESRI ArcCatalog 9.2.2.1350 Shapefile The accuracy is not based on a formal quantitative assessment. Field checking was not performed for this assignment. To attain a better estimate of accuracy, a formal re-evaluation of the political boundaries of parishes within Louisiana would be necessary. A string value (parish name) is assigned to each attribute in this project. The parish names comprise the attributes for this data set. All polygons are closed, and have been cleaned in an editing environment. Adjacent polygons do not have identical attributes. Each polygon has one and only one attribute. Processing of digital data follows conventions and standard methodologies for the time period and within limitations of available workstation equipment at the date of data development. The accuracy of this data meets the accuracy of the National Map Accuracy Standards. 40 feet The accuracy of the data set meets the National Map Accuracy Standards which is met by every topographic quadrangle utilized in this project. The National Map Accuracy Standards' horizontal accuracy requires that at least 90 percent of points tested are within 0.02 inches of the true position. The accuracy of the data set meets the National Map Accuracy Standards, which is met by every topographic quadrangle utilized in this project. National Map Accuracy Standards' vertical accuracy requires that at least 90% of well defined points tested be within one half contour interval of the correct value.

Data, in the form of a digitized overlay of parish political boundaries and territorial waters, was collected from Topographic maps of the State of Louisiana in the form of DRGs and from the Louisiana Oil Spill Contingency Plan map CD respectively. Polygons were digitized, in ArcView 3.0, on the computer screen by using a mouse to draw and move lines. Polygons were subsequently edited and assigned attributes (parish names) within the ArcView environment. The shapefiles created in ArcView were then converted to ARC/INFO format and cleaned. The final data is in the form of an ARC/INFO coverage. 19980101 The original data set was taken and projected from UTM NAD27 coordinates to geographic NAD83 decimal degree coordinates. The attribute area in acres was then added to the data set. 1999 Louisiana State University, Department of Geography and Anthropology DeWitt Braud mailing address
