NOAA-National Marine Fisheries Service: Complete Pending NMFS PRD Review

GeoPlan relied on the integrity of the attribute information within the original data.

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

This data is provided 'as is' and its horizontal positional accuracy has not been verified by GeoPlan

This data is provided 'as is' and its vertical positional accuracy has not been verified by GeoPlan

NOAA-National Marine Fisheries Service: Users be advised that the accuracy of this data set is completely dependent upon the accuracy of the shoreline and bathymetric data used in the creation process. For more details on this process, see the process description. The text description in 73 FR 72210 is always the one, true definition of Acropora critical habitat. These or any other depictions are for information purposes only and shouldn't be relied on for regulatory purposes.

The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist. Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. The University of Florida GeoPlan Center shall not be liable for any damages suffered as a result of using, modifying, contributing or distributing the materials. A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.

DATA LINEAGE SUMMARY:

Bathymetry source: NGDC Coastal Relief Model for Puerto Rico & Virgin Islands (Vol. 9), and Florida and Eastern Gulf of Mexico (Vol. 3). Using ESRI's ArcGIS ArcMap software and Spatial Analyst extension, ran the 'Surface Analysis' tool, 'Contour'. Set contour interval to 30 (CRM is in tenths of meters). The contour line was a bit blocky, so smoothed using ET GeoWizard (3rd party software) to smooth the contour using Bezier Curve smoothing algorithm with default settings (5 for smoothness) for the Caribbean and 10 for smoothing setting for Florida, and then cleaned. Converted the polyline to a polygon. Deleted very small polygons/ or polys for depths +/- 1m. Process Date: 20071030 Used detailed shoreline for Puerto Rico and the Virgin Islands from NOAA National Centers for Coastal Ocean Science (NCCOS), by selecting 'Land' and 'mangrove' polygons. Used NOAA medium resolution vector shoreline for Florida to create land polygon. Erased the bathymetry polygons with the land/mangrove polygons . For Florida shoreline, or shoreward side of the critical habitat polygon, used Florida Fish & Wildlife Commission (FWC) for near shore bathymetry (digitized from NOAA nautical charts) for the 6 ft depth to Government Cut, FWC 1:24,000 scale shoreline, COLREG lines, and intercouncil boundary between South Atlantic and Gulf of Mexico Fishery Management Councils at the mouths of bays and inlets, and information from the U.S. Navy for exclusions. The polygon that included to the 30 meter contour was erased with the appropriate data for the shoreward side. Process Date: The process of creating an outer boundary using the gridded bathymetry data produced polygons with very dense vertices. ET GeoWizards (3rd party software) was used to generalize the polygons, using the Douglas-Poiker algorithm. A generalize tolerance of .00001 arc seconds was assigned. Process Date: 03/12/2009 GeoPlan Center downloaded the Acropora (Elkhorn and Staghorn Coral) Designated Critical Habitat in Shapefile format on May 26th, 2011. The Shapefile was downloaded from: NOAA Fisheries Geographic Information Systems, Fisheries Data: Critical Habitat http://www.nmfs.noaa.gov/gis/data/critical.htm#se -Acropora_CH_po.shp -Data that was related to the State of Florida was selected out of the dataset and reprojected from Decimal Degrees WGS 1984 to FGDL Albers Conical Equal Area -Renamed layers to acropora_ch_sep09.shp -Fields SNAME, CNAME, STATE, STATUS, ACRES, DESCRIPT, and FGDLAQDATE were added and populated -Upcased all records Process Date: 20110531
