Description:

Abstract:

This data set consists of digital data describing the submerged aquatic vegetation (seagrass) beds of the Gulf Islands National Seashore in the Santa Rosa Sound of Florida in 2001. The data set was created for the National Park Service. The seagrass data were derived from interpretation of color infrared photography and mapped at 1:12,000 as hard copies to USGS digitial orthophoto quarter quadrangle base maps and digitized at the U.S. Geological Survey, National Wetlands Research Center. The data set area covers nine Florida quadrangles; Perdido Bay, Fort Barrancas, Gulf Breeze, Oriole Beach, Garcon Point, Holley, South of Holley, Navarre, and Mary Esther. The seagrass beds were classified according to a U.S. Geological Survey, National Wetlands Research Center derived classification scheme based on the C-CAP Coastal Land Cover Classification system of NOAA Coastwatch Change Analysis Project.

Purpose:

The intended use of this data set is to provide a comprehensive assessment of the distribution and extent of seagrass habitat communities along Santa Rosa Sound in Southwest Florida (Gulf Islands National Seashore.)

Access_Constraints:

It is strongly recommended that this data is directly acquired from the distributor described above or from another USGS Biological Resources Division server and not indirectly through other sources which may have changed the data in some way. The distributor makes no claims as to the data's suitability for other purposes.

Use_Constraints:

Acknowledgement of the U.S. Geological Survey, National Wetlands Research Center as a data source would be appreciated in products developed from these data, and such acknowledgment 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 U.S. Geological Survey, National Wetlands Research Center staff. 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 this data, based on the description of appropriate/inappropriate uses described in this metadata document. 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 is dependent on the expertise of the photointerpreter and the processes involved in converting the delineation to digital form. All work conducted by the photointerpreter is double-checked by another photointerpreter. Upon conversion to a digital form, an on-screen comparison with the hard copy data is performed. The accuracy of these data is believed to be high, although no formal assessment was done.

Logical_Consistency_Report:

Data are inherently polygonal. ArcGIS software is used to create and maintain topological relationships between features. Polygonal features begin and end at the same point, contain no overshoots or undershoots, and contain a single label. Linear features are continuous where appropriate, i.e., dangling arcs are removed if they are not required.

Completeness_Report:

For the cartographic process (photointerpretation), accordance with nationally accepted mapping standards and conventions are followed. For the digital conversion process, conventions and standard check list methodologies in place for the time period were followed.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The accuracy of the horizontal positions is based on the accuracy of the georeferenced data source (which can be USGS DOQQs, DEMS, flight line center points, and/or calibration reports). The sources used vary from project to project. All USGS Mapping products adhere to the National Mapping Accuracy Standard.

Process_Step:

Process_Description:

Cartographic Process - After acquiring aerial photography for the project area, stereo pairs were created and packaged according to the project boundaries. Maps for cartographic transformation were generated using USGS 1998 DOQQ's printed at desired scale with coordinate tic marks for reference. The photos were interpreted using a Bausch and Lomb stereoscope at 10x magnification. Cartographic work was performed using a Zoom Transfer Scope, and magnification varied according to the scale of the source data (photography).
