National Oceanic and Atmospheric Administration (NOAA) 20031114 vector digital data National Oceanic and Atmospheric Administration (NOAA) State of Florida National Marine Fisheries Service (NMFS), National Oceanic and Atmospheric Administration (NOAA), Department of Commerce 20000329 March, 2000 These data represent the critical habitat for Johnson's Seagrass as designated by Federal Register Vol. 65, No. 66, Wednesday, April 5, 2000, Rules and Regulations. The purpose of these data is to visually represent the critical habitat areas for GIS analysis and display. POLYGON 20031114 publication date Complete As needed -80.531980 -80.000557 27.854618 25.746727 ISO 19115 Topic Category biota None Seagrass Critical Habitat GIS Johnson's Seagrass None St. Lucie Inlet Indian River Lagoon Florida Fort Pierce Inlet Lake Wyman Hobe Sound Jupiter Inlet Biscayne Bay Sebastian Inlet Atlantic Ocean Lake Worth Lagoon Lake Worth None 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. THE DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED AS LEGALLY BINDING. 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 modelling 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.

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 epicting the federally authourized 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.) This data is provided "as is". GeoPlan relied on the integrity of the original data layer's topology. This data is provided "as is" by GeoPlan and is complete to our knowledge. 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 0 onLine Spatial and Attribute Information 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.
