FEMA Task Order number is HSFE05-11-J-0090. The area of data acquisition is for the entire county of Racine County in Wisconsin. The collection area consists of 332 square miles and was captured to the "Highest" vertical accuracy requirement. Specifications listed below are based on FEMA Procedure Memorandum No. 61 Standards for LiDAR and Other High Quality Digital Topography. This collection specification is the equivalent of a 2 foot contour accuracy, and was collected with a nominal pulse spacing of 1.3 meters. The airborne GPS and IMU data were processed immediately following each mission. In addition, a sample of the LIDAR data was post-processed at the completion of each mission and the data was reviewed to ensure planned data quality and coverage. This data set contains point cloud data(' in LAZ (compressed LAS) format', ''). The data may have been reprojected or otherwise modified from the original data in an automated process. Disregard projection information in this abstract and refer to the spatial reference section. The STARR - Racine County project is to provide high accuracy processed LiDAR data in Wisconsin. The project includes re-classification of previously collected LiDAR data to produce LAS files, contours, DTMs, DEMs and Breaklines for a 2 foot contour accuracy. The project consisted of acquisition, post-processing, and classification of LiDAR data. The classified bare-earth data achieved the following: Vertical accuracy achieved for the 332 square miles was of the Highest vertical accuracy at a RMSE Z of 0.481 ft (95% confidence level of less than 0.980 ft) or better in the "Open Terrain" land cover category. Accuracy statement is based on the area of moderate to flat terrain. Diminished accuracies are to be expected in areas of dense vegetation. The accuracy of the LiDAR data as tested met the vertical accuracy or better, however, derived products may be less accurate in areas of dense vegetation due to a lesser number of points defining the bare-earth in these areas.

The 332 square miles of data was acquired at 1700 meters above ground level (AGL) and has a horizontal accuracy of 0.31 meters. Vertical Positional Accuracy Ground survey check points were collected by Quantum Spatial for use in data set positional reference and vertical accuracy evaluation. In vertical accuracy evaluation, the ground survey check points of various ground cover categories are compared to vertical values of a Triangulated Integrated Network (TIN) derived from the LiDAR data, differences in elevation are calculated to establish a RMSE. Two check point ground surveys were made performed between March 2010 - March of 2011 and another survey was performed February 2013. Ground cover categories include Hard Surface, Short Grass, Tall Grass, Brush and Forest. The Fundamental Vertical Accuracy (FVA) of the Classified Bare Earth for the STARR Racine County project achieved a RMSE of 0.500 ft (95% confidence level of less than 0.980 ft) in the "Open Terrain" land cover category against the Triangulated Integrated Network (TIN). 46 control points were used in this evaluation. The Supplemental Vertical Accuracy (SVA) of the Low Grass achieved a RMSE of 0.444 ft (95th Percentile of less than 0.751 ft) against the Triangulated Integrated Network (TIN). 44 points were used in this evaluation. The Supplemental Vertical Accuracy (SVA) of the Long Grass achieved a RMSE of 0.485 ft (95th Percentile of less than 0.977 ft) against the Triangulated Integrated Network (TIN). 45 points were used in this evaluation. The Supplemental Vertical Accuracy (SVA) of the Brush achieved a RMSE of 0.466 ft (95th Percentile of less than 0.748 ft) against the Triangulated Integrated Network (TIN). 43 points were used in this evaluation. The Supplemental Vertical Accuracy (SVA) of the Forest achieved a RMSE of 0.507 ft (95th Percentile less than 0.860 ft) against the Triangulated Integrated Network (TIN). 45 points were used in this evaluation. The Consolidated Vertical Accuracy (CVA) of all categories achieved a RMSE of 0.481 ft (95th Percentile of less than 0.920 ft) against the Triangulated Integrated Network (TIN). 223 checkpoints were used in this evaluation. Completeness Report Complete Conceptual Consistency None Ground based survey points were compared to the LiDAR airborne data points. Two hundred twenty-three survey points were collected throughout Racine County in various ground cover categories. 2013-12-20T00:00:00 The LiDAR data was captured using Quantum Spatial's twin-engine AeroCommander 500 or a Cessna 320 with an Optech ALTM Gemini LiDAR system. This system consists of a Airborne Global Position System (ABGPS), inertial measurement unit (IMU), and laser sensor. The ABGPS collects XYZ coordinates of the laser sensor and the IMU calibrates the orientation of the aircraft. During flight, laser pulses are reflected from features on the surface and the system collects this data. The acquired LiDAR data receives a preliminary review to assure that complete coverage is obtained and to ensure the absence of data gaps. Acquisition parameters: 1. Scanner - Optech ALTM Gemini LIDAR 2. Flight Height - 1700 meters above ground level 3. Swath Width - 44 degrees 4. Sidelap - 55% 5. Nominal Point Spacing - 1.3m GPS and IMU processing parameters: 1. Processing Programs and version - Applanix POSPac, version 4.4 2. IMU processing monitored for consistency and smoothness - Yes. 2013-12-21T00:00:00 Point Cloud Processing: 1.

Geoid Model used to reduce satellite derived elevations to orthometric heights - Geoid09 (Meters). LIDAR Processing: 1. Processing Programs and versions - TerraSolid TerraScan (version 013.020), TerraModeler (version 013.005) and TerraMatch (version 013.009), Intergraph MicroStation (version 08.05.02.70), and GeoCue (version 2013.1.45.1) GlobalMapper (version 13.2.1). 2. Point Cloud data is imported to TerraScan in a Microstation V8 (V) CAD environment on a specified 1500m by 1500m tiling scheme 3. Analyze the data for overall completeness and consistency. This is to ensure that there are no voids in the data collection. 4. QC (Quality Control) for calibration errors in the dataset. This is accomplished by sampling the data collected accross all flight lines and classify the individual lines to ground. The software will use the ground-classified lines to compute corrections (Heading, Pitch, Roll, and Scale). 5. Orientation corrections (i.e. Calibration corrections) are then applied (if needed) to the entire dataset. 6. Automatic ground classification is performed using algorithms with customized parameters to best fit the project area. Several areas of varying relief and planimetric features were inspected to verify the final ground surface. 7. Quantum Spatial provided Quality Assurance and Quality Control (QAQC) data for this project. Quantum Spatial processed QA/QC points in 'open terrian' land cover category that were used to test the accuracy of the LiDAR ground surface. TerraScan's Output Control Report (OCR) was used to compare the QAQC data to the LIDAR data. This routine searches the LIDAR dataset by X and Y coordinate, finds the closest LIDAR point and compares the vertical (Z) values to the known data collected in the field. Based on the QAQC data, a bias adjustment was determined, and the results were applied to the LIDAR data. 8. Once the automatic processing and testing of LiDAR is complete, Quantum Spatial meticulously reviews the generated bare-earth surface data to insure that proper classification was achieved as part of a Quality Control process. Point classification follows the standard established by The American Society for Photogrammetry and Remote Sensing (ASPRS).

A routine is used to drape line work following monotonic elevation change of drainage. 10. Final deliverables are generated and output to a client specified PLSS tiling scheme. 2013-12-30T00:00:00 Data were retrieved from the Wisconsin View website in LAS format, NAD83(2007) UTM 16N projection with NAVD88 (Geoid09) vertical meters.
