GeoPlan relied on the integrity of the attribute information within
the original data.
In addition to the coordinates provided in the Federal Register document, the 
following data were used to assist in the production of this dataset: US Army Corps 
of Engineers - IWW_IR to DA.dgn (Microstation Design File depicting the 
Intracoastal Waterway), Miami Harbor 83-90.dgn (Microstation Design File depicting
the federally authorized navigation channels in Miami Harbor; According to the 
USACE, these channels are likely to be updated in the near future). St. John's River
Water Management District - cb24_det.e00 (ArcInfo Interchange format file, 
converted to an ArcInfo Coverage depicting a detailed shoreline, last update 
12/10/99.) Edited February 2012. See process steps.

The purpose of these data is to visually represent the 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

Due to the collection of data used in this analysis from multiple data sources, some 
instances occur where the USACE ICW file intersects areas of the SJRWMD file 
classified as "Land", particularly in the vicinity of Hobe Sound. Clearly this is not the 
real world situation and efforts will be made to resolve these conflicts in the data. At 
this time, these were the best data available. The text description in 50 CFR Part 
226 is always the one, true definition of Johnson's seagrass critical habitat. These or
any other depictions are for information purposes only and shouldn't be relied on for 
regulatory purposes.

*** Shorelines/Base Layers *** The accuracy of this dataset is dependent upon the

were selected for their suitability to a broad audience, and may not be suitable for 
specific uses requiring higher-resolution information. Coastlines change. Unless 
otherwise noted, where the NOAA Medium Resolution Shoreline is used, assume 
the regulatory boundary reaches the most current coastline delineation available.

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.

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. For more information regarding

Critical Habitat Designations, Maps, and GIS Data

Southeast NOAA Fisheries Region: critical habitat maps and data

A point layer was created using the coordinates in the Federal Register. Those 
points were then used to digitize polygons. The polygons were then "clipped" to a 
detailed shoreline (cb24_det.e00) obtained from St. John's River Water 
Management District (SJRWMD). Following the clip operation, microstation design 
files of the ICW and Miami Harbor navigation channels were obtained from the US 
Army Corps of Engineers (USACE) and converted to shapefiles. The final ICW 
shapefile was created by using a 62.5ft buffer on either side of the centerline and 
editing that buffer file to match the widening areas in the vicinity of the critical 
habitat areas. The final Miami Harbor shapefile was created by digitizing a polygon 
over the channel edge line work in the design file. An Edit Clip was then performed 
to "punch a hole" through the Critical Habitat areas where they intersected the ICW
and the Miami Harbor navigation channel, thus excluding the federally authorized 
navigation channels from the Critical Habitat areas. Finally, the data in the vicinity of 
Miami Harbor in Biscayne Bay were edited visually to correspond to the paper maps 
in the federal register document. Additionally, all data used were reprojected to 
match the detailed shoreline. (UTM Zone 17, NAD 83, HARN)
Process Date: 20031114

2011/2012 edits to shapefile: (a) Indian River north Sebastian Inlet: I recreated the polygon according to eCFR 50 CFR 226.213 in 2007. (b) Indian River south Sebastian Inlet: OK (c) Indian River Lagoon - Fort Pierce inlet: OK (d) Indian River Lagoon - St. Lucie Inlet: I included the ICW in the shapefile, and created one solid polygon. I also redigitized the eastern side along the shoreline using Bing Maps as a background in ArcMap. (e) Hobe Sound: The coordinate in the FR is suppose to be at SR 708, but looking at Bing Maps, it is to the south. I edited the shapefile to continue north to SR 708. I also made one big poly that does not depict the ICW exclusion. The polygon shorelines were also edited to follow the Bing Maps background. (f) Jupiter Inlet: I digitized a boundary that followed the shoreline (again, employing heads-up digitizing techniques using Bing Maps). (g) Lake Worth: the original shapefile had a 4 vertice polygon that approximated the shoreline on the south side. I digitized the shoreline along the south side using Bing Maps as a guide. (h) Lake Worth Lagoon - Boynton Inlet: I edited the polygon to go all the way to the coordinates (the shape file does not exclude the ICW). I also redigitized the western edge to follow the Bing Maps shoreline. (i) Lake Wyman: The original shapefile excluded the ICW, so I redigitized the polygon to extend to the published coordinates. This unit did not follow the shoreline on the eastern side, so I redigitized it to follow the Bing Maps shoreline. (j) A portion of Northern Biscayne Bay, FL: I received a new Biscayne Bay Aquatic Preserve boundary from Florida DEP, Bureau of Survey and Mapping, Division of State Lands (rev. 2010). The boundary is from Section 258.39 (11) Florida Statutes, and Section 258.397. They send me the exterior boundary for the AP. They said that the law for the boundary has not changed, but the boundary is more accurate now. If there are questions about specific sites within the boundary, contact the Title and Land Records Section of the Bureau of Survey and Mapping Division of State Lands (850)245-2788.
