  Description:
    Abstract:
      These inundation surfaces were creating using the United States Army Corps of Engineers (USACE) sea level change projection curves (as specified in USACE Engineer Circular EC 1165-2-12), NOAA tide gauge data, and a 5-meter horizontal resolution Digital Elevation Model (DEM). A simple bathtub method was initially used to create the surfaces, and then the surfaces were enhanced with a hydrologic connectivity filter, which removes isolated inundated areas not connected to an ocean, gulf, or major waterway. The inundation surfaces in this download are in vector feature class format, and include both the bathtub inundation surfaces (feature classes with the "_BATHTUB" suffix) and the enhanced inundation surfaces with the hydrologic connectivity filter applied (features classes without the "_BATHTUB" suffix. These surfaces can also be downloaded as rasters (their native format). For more information and full technical methods, please see the final report on the project website: <http://sls.geoplan.ufl.edu>
    Purpose:
      The UF GeoPlan Center created these inundation surfaces as part of the Sea Level Scenario Sketch Planning Tool, which was developed under contract with the Florida Department of Transportation. The Sea Level Scenario Sketch Planning Tool is a series of tools and data intended to assist with the identification of potentially vulnerable transporation infrastructure due to inundation from sea level change.

  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report:
        Horizontal accuracy of these inundation surfaces can be approximated from the DEM used to create the surfaces. The horizontal accuracy of the DEM used is approximately 5.433 meters, which is the cell size of the DEM.
    Vertical_Positional_Accuracy:
      Vertical_Positional_Accuracy_Report:
        The vertical accuracy of these inundation surfaces can be approximated from the accuracy reports of the Lidar data, which was used to derive the DEM used to create these inundation surfaces. A review of the accuracy reports submitted with the coastal Lidar data accepted by the FDEM reports the vertical accuracy of collected Lidar data in terms of root mean square error (RMSE). The overall average RMSE for this data throughout all land cover categories is 11.87cm (4.68 inches). This translates to a 66% chance that a feature with an elevation equivalent to 4.68 inches will be correctly located on the DEM. The 95% confidence interval provides a more appropriate and acceptable probability, equivalent to 23.26cm (9.16 inches). Since the DEM and projected SLC values are calculated as integers, this translates to a 10 inch minimum vertical mapping resolution. Hence, any projected SLC that yields inundation levels equal to or greater than 10 inches have a 95% chance of being accurately mapped on the DEM.

      Process_Description:
        The USACE sea level curve calculator spreadsheet was downloaded from the USACE website: <http://www.corpsclimate.us/ccaceslcurves.cfm> and used to create sea level change projections. Sea level change projection values were then converted to NAVD88 datum. For FDOT District-wide inundation surfaces, an area weighted mean process was used to calculate sea level change values where multiple tide stations were in proximity to the coastline of the respective District. For the Statewide inundation surfaces, the values from the Key West tide station were used.
        Inundation surfaces were then creating by selecting elevations equal to or below the sea level change value. Resulting inundation surfaces are a single-value raster layer with the value indicating the presence of inundation, and a null value indicating the absence of inundation. The single-value in the grid represents the sea level change value after conversion to NAVD88 (where necessary) and calculation of the area weighted mean (for FDOT District surfaces).
        The raster inundation surfaces were then converted to both multi-part and single-part shapefiles for processing GIS intersections of the data.
        A 5-meter Digital Elevation Model (DEM) created by the UF GeoPlan Center was used to create all inundation surfaces. The DEM can be downloaded from the Florida Geographic Data Library (FGDL) at:<http://www.fgdl.org>. FGDL DEM filename is FLIDAR_MOSAIC_IN, and title is "FLORIDA DIGITAL ELEVATION MODEL (DEM) MOSAIC - 5-METER CELL SIZE - ELEVATION UNITS INCHES"

    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.
