Sanborn Map Company 20090925 Unknown HYDROGRAPHICFEATURE vector digital data HYDROGRAPHICFEATURE withheld Lidar generated breaklines for S.C. Dept. of Natural Resources. Single Line Feature: linear hydrographic features such as stream and canal centerlines, shorelines, ridge lines, road crowns, tops and bottom of stream banks, embankments, etc. Dual Line Feature: linear hydrographic features such as streams, rivers, canals, etc. with a width greater than 40 feet. Bridge, overpass, or box culverts (greater than 24 feet in width) features: Feature should show edge of bridge, overpass, or box culvert. Closed water bodies: land/water boundaries of constant elevation water bodies such as lakes, reservoirs, ponds, etc. Features shall be defined as closed polygons and contain an elevation value that reflects the best estimate of the water elevation at the time of data capture. Water body features are be captured for features quarter acres in size or greater. Donuts will exist where there are islands within a closed water body feature. 3-dimensional breaklines were delineated to help describe a change in the smoothness or continuity of a surface and to ensure the Digital Terrain Model (DTM) is hydrologically correct. en 20090925 publication date Complete Unknown -80.792967 -80.075435 33.335336 32.815921 2060642.055446 2285015.890092 354999.999672 550000.532152 -34.652000 131.980000 None Breakline DTM DSM Contour Elevation Lidargrammetry Lidar None South Carolina Dorchester County United States This data may be used by the requested party for stated purposes and should not be re-distributed.

Hydro connectivity, monotonicity and vertical consistency of the breaklines were validated. A visual qualitative assessment was performed to ensure the data completeness against the intensity images derived from Lidar points. The 3D breaklines inherit the accuracy of the Lidar stereo pairs it was acquired from. Lidar source compiled to meet 1m horizontal accuracy. The 3D breaklines inherit the accuracy of the Lidar stereo pairs it was acquired from. S.C. Dept. of Natural Resources Unknown Unknown LiDAR vector digital data LiDAR Survey of Dorchester County, SC, under a contract with SCDNR. online 2009 publication date LiDAR LiDAR dataset was used to create intensity stereo pairs for 3D breakline compilation. The ABGPS, IMU, and raw Leica ALS-50 LiDAR data are integrated into the LEICA ALS post processor software. The resultant file is in a LAS binary file format. The LAS file version 1.1 formats 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 horizontal datum and GRS80 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. withheld withheld withheld 2009 withheld S.C.

A combination of proprietary filters is 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. withheld 2009 withheld S.C. Dept. of Natural Resources James D.
