Description:
Abstract:
Digital Elevation Model for the eastern half of Seminole County plus portions of north central and northeast Orange County. Collected in support of Central Florida Coordination Area (CFCA) projects. Derived from a terrain dataset created from LiDAR data acquired in February of 2009. Grid cell size is 5 feet; vertical datum is NAVD88.
Purpose:
Raster grid contains information that will be used to create hydraulic and hydrologic models.

Source_Contribution:
The Light Detection and Ranging (LiDAR) LAS dataset is a topographic survey conducted for the St. Johns River Water Management District. The 3d Breakline collection was done utilizing MARS proprietary software.
Process_Step:
Process_Description:
The ABGPS, IMU, and raw Leica ALS50 LiDAR data are integrated with Leica's Incorporated's ALS Post Processor software. The resultant file is in a LAS binary file format . The LAS file version 1.1 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 geodetic coordinates referenced to the NAD83 HARN horizontal datum and NAVD88 vertical datum. The date and time for each flight line can be determined using the Julian date and time. The Julian date is a continuous count of days and fractions since noon Universal Time on January 1, 4713 BCE on the Julian Calendar.

Process_Description:
The unedited data are classified to facilitate the application of the appropriate feature extraction filters. A combination of proprietary filters are applied as appropriate for the production of bare earth digital terrain models (dtms). Interactive editing methods are applied to those areas where it is inappropriate or impossible to use the feature extraction filters, based upon the design criteria and/or limitations of the relevant filters. These same feature extraction filters are used to produce elevation height surfaces. The LiDAR mass points were delivered in American Society for Photogrammetry and Remote Sensing LAS 1.1 format. The header file for each dataset is complete as define by the LAS 1.1 specification. In addition the following fields are included: Flight Date Julian, Year, and Class. The data was classified as follows: Class 1 = Unclassified. This class includes vegetation, buildings, noise etc. Class 2 = Ground Class 7= Noise Class 9 = Water Class 12= Overlap

Process_Description:
The DEM was created from a terrain (delivered by PDS) using ArcCatalog's 'Terrain to Raster' tool. 'Natural Neighbors' was chosen as the sampling method and a cell size of 1.524 meters (5 feet) was designated. The project boundary was edited by erasing areas along the border that intersected with selected waterbody features. The edited project boundary was used as a mask to remove DEM artifacts in the water.
