Item Identification

Title: Gulf Sturgeon (polygon)
Status: Completed
Publication Date: 2003-03-19

These data represent the marine and estuarine critical habitat, Units 8 through 14, for Gulf Sturgeon as designated by Federal Register Vol. 68, No. 53, Wednesday, March 19, 2003, Rules and Regulations. There is a separate geospatial dataset that shows the riverine critical habitat, Units 1 through 7.


The purpose of these data is to visually represent the critical habitat areas for GIS analysis and display.

Access Information

Security Class: Unclassified
Data Use Constraints:

The GIS files and their associated coordinates are not the legal source for determining the critical habitat boundaries of species described in this dataset, but are used to identify areas which contain the physical and biological features essential to the conservation of the species or areas otherwise determined to be essential. Inherent in any dataset used to develop graphical representations, are limitations of accuracy as determined, among others, the source, scale and resolution of the data. While the NOAA National Marine Fisheries Service (NMFS) makes every effort to represent the critical habitat shown with data as completely and accurately as possible (given existing time and resource constraints), the NMFS gives no warranty, expressed or implied, as to the accuracy, reliability, or completeness of these data. In addition, the NMFS shall not be held liable for improper or incorrect use of the data described and/or contained herein. Graphical representations provided by the use of these data do not represent a legal description of the critical habitat boundary. The user is referred to the critical habitat textual description in the appropriate final rule for this species as published in the Federal Register. These data are to be used only in the context of the definition and purpose of critical habitat. This primarily relates to Section 7 consultation under the Endangered Species Act. These data may be used for planning and land management purposes. They are not to be used for legal survey use. Please refer to Federal Register Citation Number 68FR13370, published 20030319 for the legal critical habitat information.

Process Steps

Process Step 1

CC ID: 1083529

The base shoreline data set used in this process was the Coastal Assessment Framework shapefile from NOAA/NOS/SPO. Additional reference data sets included Mr SID CIR Imagery of the Lake Pontchartrain Causeway from, TIGER Line shapefiles of roads in Louisiana and Florida from and road and railroad shapefiles in Mississippi from MARIS. Maptech's Digital Chart Kit, Regions 8 and 17 featuring NOAA Digital Charts and a text description of the 72 COLREGS Demarcation lines from were also used. These additional layers were used to designate boundaries on individual units as dictated by the critical habitat designations described in the Federal Register Document.Inland units were created by digitizing a polygon slightly larger than the water body it represented. The new polygons were then "edit clipped" to the shoreline to exactly match the shoreline. In areas where the entire water body was not included, the boundaries were drawn following the feature described in Federal Register document. (Ex. The Lake Pontchartrain Causeway was digitized from the Mr SID's and used as the western boundary of the polygon. Bays with adjacent rivers or bayous that were excluded had their boundaries created by drawing a straight line across the river's mouth as dictated by the Document.) Every effort was made to exclude features at locations consistent with the descriptions in the Document.Near shore units were created by creating a 1 nautical mile buffer of the coastline (9nm in the case of the Suwannee Sound) or barrier island as indicated by the Document. The seaward side of these buffers was used as the southern boundary of the units. For the passes between islands, line segments were digitized to represent the 72 COLREGS Demarcation lines and 1 nautical mile buffers were created from those lines. Those buffers were merged with the buffers of the islands to complete the southern boundaries of the units. Every effort was made to accurately follow the descriptions of the 72 COLREGS lines. Whenever coordinates were used in the description, those coordinates were used in the creation of the buffers. When no coordinates were given, the lines/buffers were created by following the descriptions in the text.The Maptech software was used primarily as a guide to locate areas by name. The digital charts were also useful for accuracy evaluation in placement of the 72 COLREGS lines, as they were visible on the charts and could be compared to the lines digitized from text descriptions.
