Identification_Information: Citation: Citation_Information: Originator: United States Geological Survey, Biological Resources Division's, National Wetlands Research Center Publication_Date: 19980512 Title: Political Boundaries of Parishes within the State of Louisiana Geospatial_Data_Presentation_Form: Vector Digital Data Description: Abstract: 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 the boundary information from the Digital Raster Graphic Maps (DRGs) of 7.5 Minute Topographic Quadrangles and merging the Louisiana territorial waters from the Louisiana Oil Spill Contingency Plan Map CD to create a digitized overlay of Louisiana political boundaries for all parishes. Purpose: To create a digitized overlay of the State of Louisiana, highlighting the political boundaries for all parishes.

Native_Data_Set_Environment: The dataset of Louisiana Parish Political Boundaries was digitized in Arcview 3+ utilizing polygon topology and was then converted to an ARC/INFO coverage . The computer operating system platform was NT. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: 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. Quantitative_Attribute_Accuracy_Assessment: Attribute_Accuracy_Value: A string value (parish name) is assigned to each attribute in this project. Attribute_Accuracy_Explanation: The parish names comprise the attributes for this dataset. Logical_Consistency_Report: 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. Completeness_Report: 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. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The accuracy of this data meets the accuracy of the National Map Accuracy Standards. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 40 feet Horizontal_Positional_Accuracy_Explanation: The accuracy of the dataset 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. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: 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.

Process_Step: Process_Description: 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 DRG's and from the Louisiana Oil Spill Contingency Plan map CD respectively. Polygons were digitized, in ArcView 3+, 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.
