Florida DEM 20080327 Unknown vector digital data \\CFMCIFS01\ENG\Storm Water\TMDLs\Caloosahatchee_River\Data\CFM_Data\Hydrographicfeature.shp Hydrographicfeature This data set is one component of a digital terrain model (DTM) for the Florida Division of Emergency Management's (FDEM) Project Management and Technical Services for Mapping within Coastal Florida (Contract 07-HS-34-14-00-22-469), encompassing the entire coastline of Florida. The dataset is comprised of mass points, 2-D and 3-D breakline features, 1-foot and 2-foot contours, ground control, vertical test points, and a footprint of the data set, in the ESRI ArcGIS File Geodatabase format. In accordance with the Baseline Specifications 1.2, the following breakline features are contained within the database: closed water bodies (lakes, reservoirs, etc) as 2-D or 3-D polygons; linear hydrographic features (streams, shorelines, canals, swales, embankments, etc) as 3-D breaklines; coastal shorelines as 2-D or 3-D linear features; edge of pavement road features as 3-D breaklines; soft features (ridges, valleys, etc.) as 3-D breaklines; low confidence areas as 2-D polygons; island features as 2-D or 3-D polygons; overpasses and bridges as 3-D breaklines. Contours were generated from a gridded DEM: 2-foot contours meet National Map Accuracy Standards, with 1-foot contours for visualization purposes. The LiDAR masspoints are delivered in the LAS file format based on the FDEM's 5,000' by 5,000' grid. Breakline features were captured to develop a hydrologically correct DTM. Bare earth LiDAR masspoint data display a vertical accuracy of at least 0.3-feet root mean square error (RMSE) in open unobscured areas. The DTM was developed to support the Florida Division of Emergency Management (FDEM) development and maintenance of Regional Evacuation Studies (Study), which include vulnerability assessments and assist disaster response personnel in understanding threats to Florida's citizens and visitors. Breaklines improve the digital elevation model in areas where the point density is insufficient.

Tallahassee Florida 32399-2100 USA 850-413-9907 850-488-1016 gis@dca.state.fl.us Microsoft Windows 2000 Version 5.2 (Build 3790) Service Pack 2; ESRI ArcCatalog 9.3.1.3000 Shapefile Hydrographic features (streams, shorelines, canals, swales, embankments, etc.) are captured as three-dimensional breaklines with varying elevations. Stream/river features that are 0.5 miles or greater in length are captured. Features that are 8 feet or less in width are captured as single breakline features. Features that are greater than 8 feet in width are captured as double line features. Linear hydrographic features are carried through and/or under bridges to the best of the operator's ability to see. These breaklines were determined from LiDAR and stereo tile (LiDARgrammetry) data of specific dates and that model the land/water contributions and extents on those dates. The 3-D vector line work was created using stereo-compilation. A thorough QC procedure was implemented to verify the elevation of the breaklines and to ensure no zero elevations were found except in coastal areas where it is possible to find z values equal to mean sea level. Additional QC steps were taken to ensure all breaklines agree with the vertical location of the LiDAR. The DTM was developed in accordance with the Baseline Specifications 1.2. The DTM is intended to support 2-foot contours, and the vertical accuracy of ground points in unobscured areas is not to exceed 0.6-feet RMSE. A thorough QC was implemented to verify the breakline elevation accuracy. This feature class represents the complete set of data for 576 tiles within Delivery Area E, 578 tiles within Delivery Area F in Charlotte and Lee Counties, and 174 tiles within the Buy-up area in Lee County. Horizontal accuracy is +/- 3.8-foot at the 95% confidence level using RMSE(r) x 1.7308 as defined by the FGDC Geospatial Positional Accuracy Standards, Part 3: NSSDA. 3.8 LiDAR system calibration is available in the MTS Report of Topographic Survey. 0.3-feet RMSE for unobscured ground points. The accuracy assessment was performed using a standard method to compute the root mean square error (RMSE) based on a comparison of ground control points and filtered LiDAR data points. Filtered LiDAR data has had vegetation and cultural features removed and by analysis represents bare earth elevations. The RMSE figure was used to compute the vertical National Standard for Spatial Data Accuracy (NSSDA). 0.3-feet RMSE - tested The accuracy assessment was performed using a standard method to compute the root mean square error (RMSE) based on a comparison of ground control points and filtered LiDAR data points. Results for this delivery area are available in the MTS Report of Topographic Survey. Florida DEM Woolpert, Inc. 20080327 Unknown vector digital data 24,000 disc 20080327 ground condition LiDAR The LiDAR Project Survey was acquired for the Florida Division of Emergency Management and processed by Woolpert Inc. To collect the breaklines, the LiDAR data was used as the main source data set in addition to orthophotography. Orthophoto imagery for the area within Lee County was from new imagery collected and developed by the Woolpert Team. All imagery for Lee County is dated 2007 with a 0.5-foot pixel resolution. Orthophoto imagery for the areas within Charlotte County was provided by FDEM, and was provided at 1.0-foot pixel resolution and dated 2006. The Airborne Global Positioning System (ABGPS), inertial measurement unit (IMU), and raw scans are collected during the LiDAR aerial survey. The ABGPS monitors the xyz position of the sensor and the IMU monitors the orientation. During the aerial survey laser pulses reflected from features on the ground surface are detected by the receiver optics and collected by the data logger. GPS locations are based on data collected by receivers on the aircraft and base stations on the ground. The ground base stations are placed no more than 20 mile radius from the flight survey area.

The resultant file is in a LAS binary 1.1 file format. The LAS file format can be easily transferred from one file format to another. It is a binary file format that maintains information specific to the LiDAR data (return#, intensity value, xyz, etc.). The resultant points are produced in the Florida State Plane West Zone coordinate system, with units in feet and referenced to the NAD83/90 HARN horizontal datum and NAVD88 vertical datum.
