Abstract:
Sanborn Map Company furnished the collection and processing, and development of Lidar and aerial photography to support the FEMA mapping requirements for 25 stream miles of corridor totaling 11.3 sq miles on the Winooski River located in Washington Co VT. In addition , Sanborn mapped 31.7 stream miles of corridor for the Otter Creek and East Creek located in Rutland Co VT.The project area was defined using a 1200' buffer limits along either side of the stream centerline. All data was acquired from November 12-20 . 2005. (Source: FEMA Guidelines and Specifications, Appendix N, Section N.1.2).
Purpose:
The LIDAR derived data sets, including a Gridded DEM, TIN file, 2' contours and a mass point and Breaklines file to support Camp Dresser and McKee's continued development of updated Digital Flood Insurance Rate Maps and flood insurance studies for the Otter Creek and Winooski Creeks watershed located in Rutland and Washington Countiues Vermont. (Source: FEMA Guidelines and Specs, Appendix N)
Supplemental_Information:
The TIN is part of a suite of spatial data products generated using Lidar and aerial photogrammetric technology. The TIN data represents the filtered and stereo breakline enhanced bare earth data.

Data_Quality_Information:
Logical_Consistency_Report:
Sanborn used proprietary algorithms to remove features and artifacts in the first and last return data that did not reflect true ground elevations. New aerial stereo photography was flow, and aerial triangulated to allow production of breakline ehnacement of the Bare earth Dem and to hydrologicall enforce contours and elevation data thru the compilation of drainage breaklines
Completeness_Report:
Data contained in the Terrain package highlights specific issues in the Elevation datasets. Terrain data are derived datasets that aid automated hydrologic and hydraulic analyses, the flood hazard area boundary delineations, and quality control.

Process_Description:
Step 1- Lidar data Acquisition and Raw point cloud data process- Sanborn flew the two project areasas a blocks totaling more than 50 square miles using the ALTM 2050 Lidar sensor equiped with Airborne GPS and IMU positioning and orientation units. The data was collected on Nov. 18,19, and 20 2005. The Flight plan for the project includes the following specifications to fully meet the project requirements. * single pass density of approximately 1.0 square meters per sample *Average area sampling density - 1.3 square meters per sample *Swath width 728 meters * Flight altitude 1000 meters * flight line spacing -589 meters with 125 meters overlap *Scan Frequency- 35 Hz *Scan Angle- 20 degrees * Aircraft ground speed -- 140 knots * System Calibration pre and post mission * Two GPS base stations within 30 KM</procdesc> <procsv>Applanix POsPac software for AGPS and IMU processing--Optec Realm software for point cloud gereferencing.--</procsv>
