This digital data is produced for the purposes of updating/creating a DFIRM database. Quality control checkpoints were collected by CompassData, Inc. Woolpert, Inc. performed LiDAR processing. Quality Control was performed by CompassData, Inc. Quality Assurance testing was conducted by Greenhorne & O'Mara, Inc. All firms were under contract to STARR, A Joint Venture which held the FEMA contract and task order for this work. Survey data have been confirmed to be in proper units, coordinate systems and format. The terrain data have been confirmed as complete LAS format data files. Header files are in proper LAS format with content as specified by FEMA Procedural Memo No. 61. Survey data have been checked for completeness, points have been collected in correct vegetation units, and distributed throughout the AOI. The terrain data have been checked for completeness against AOI polygons. No gaps as defined by FEMA Procedural Memo No. 61 are known to exist within the dataset. However, one area within the southeast portion of the project area was intermittently affected by flooding in the low lying agricultural fields adjacent to the Ohio River. This area presents itself as a data void, but in reality is due to water in the fields, located in Gallatin County IL, which have a history of flooding due to their geological makeup and proximity to the river. These areas (former oxbow lakes) are former meanders of the nearby river that contain water or are saturated with water for major portions of the year. The easting and northing coordinates represent the corners of an approximate boundary of the area. This boundary follows the bend of the river in the flood-affected area.Top Left: X: 402939.6 Y: 418185.3, Top Right: X: 409656.3 Y: 4181932.9, Bottom Left: 398209.6 Y: 4158042.5, Bottom Right: X: 403635.1 Y: 4157990.7. Deliverables were tested by for both vertical and horizontal accuracy. The vertical unit of the data file is in meters with 2-decimal point precision. 0.17 Consolidated Vertical Accuracy (CVA) equal to the 95% confidence level (RMSE[z] x 1.9600) calculated in open terrain, urban environment, tall grass and cropland, and forest.

STARR 2012 DIGITAL 20120430 ground condition Other7 Fully Classified LAS 1.2 dataset includes Class 2 - Bare Earth, and Class 8 - Model Key Points. GPS based surveys were utilized to support testing of LiDAR data. Geographically distinct ground points were surveyed using GPS technology throughout the area to provide Consolidated Vertical Accuracy (CVA) checkpoints to allow vertical testing of the bare-earth processed LiDAR data in different classes of land cover, including: Open (pavement, open dirt, short grass), High Grass and Crops, Forest, Urban. To accomplish this, survey-grade Trimble R-8 GPS receivers were used to collect a series of control points located on open areas, free of excessive or significant slope, and at least 5 meters away from any significant terrain break. In order to successfully collect the Forest land cover class, it was necessary to establish a Backsight and Initial Point with the R8 receiver, and then employ a Nikon Total Station to observe a retroreflective prism stationed under tree canopy. This was necessary due to the reduced GPS performance and degradation of signal under tree canopy. The R-8 receivers were equipped with cellular modems to receive real-time correction signals from the Keystone Precision Virtual Reference Station (VRS) network. Use of the VRS network allowed rapid collection times (~3 minutes/point) at 2.54 cm (1 inch) initial accuracy. All points collected were below the 8cm specification for testing 24cm, Highest category LiDAR data. To ensure valid in-field collections, an NGS monument with suitable vertical reporting was measured using the same equipment and procedures used for the CVA points on a daily basis. The measurement was compared to the NGS published values to ensure that the GPS collection schema was producing valid data and as a physical proof point of quality of collection. Those monument measurements are summarized in the Accuracy report included in the data delivered to FEMA. 59 CVA points were collected. The following software packages and utilities were used to control the GPS receiver in the field during data collection, and then ingest and export the collected GPS data for all points: Trimble Survey Controller, Trimble Pathfinder Office. The following software utilities were used to translate the collected Latitude/Longitude Decimal Degree HAE GPS data for all points into Latitude/Longitude Degrees/Minutes/Seconds for checking the collected monument data against the published NGS Datasheet Lat/Long DMS values and into UTM NAD83 Northings/Eastings: U.S. Army Corps of Engineers CorpsCon, National Geodetic Survey Geoid09NAVD88. MSL values were determined using the most recent NGS-approved geoid model to generate geoid separation values for each Lat/Long coordinate pair. In this fashion, Orthometric heights were determined for each Control, FVA and CVA point by subtracting the generated Geoid Separation value from the Ellipsoidal Height (HAE) for publication and use as MSL NAVD88(09). 20120101 The point cloud data was initially classified via formal data reduction. Woolpert LiDAR specialists develop a ground filtering routine designed to best define the terrain and also to include any non ground classes specified by the client. In the case of this project, classes 1 (default), 2 (ground), 6 (building), 7 (outlier), 8 (keypoint), and 11 (withheld) were specified. The entire classified data set is then reviewed by Woolpert LiDAR technicians to properly reclassify any artifacts and to ensure all specified classes are properly classified. Following the data review the entire data set is run through a process to include full LAS 1.2 header information. The classification and quality control of LiDAR data is carried out using a combination of Woolpert proprietary software and TerraScan software by Terrasolid Limited. The data was delivered in 1500m x 1500m tiles. 20120101 Independent QC was conducted by CompassData, Inc. by providing 'blind' checkpoint coordinates which were conflated against a surface produced from the calibrated LAS points by Woolpert. The tested z values were returned to CompassData for comparison to the surveyed z values. RMSE and 95% Confidence Level values were calculated and reported to STARR. 20120101 Universal Transverse Mercator 16 0.999600 -87.000000 0.000000 500000.000000 0.000000 coordinate pair 0.000010 0.000010 meters North American Datum 1983 Geodetic Reference System 80 6378137.00 298.257222 North American Vertical Datum of 1988 0.01 meters Attribute values Terrain\2149983\SupplementalData\Saline_CVA Survey for Horizontal and Vertical LiDAR QC FEMA Guidelines and Specifications for Flood Hazard Mapping Partners, Appendix M: Data Capture Standards and Data Capture Guidelines (available at http://www.fema.gov/fhm/dl_cgs.shtm) Terrain\2149983\Supplemental_Data\Saline_Collection_Area Area Spatial File FEMA Guidelines and Specifications for Flood Hazard Mapping Partners, Appendix M: Data Capture Standards and Data Capture Guidelines (available at http://www.fema.gov/fhm/dl_cgs.shtm) Terrain\2149983\Saline_Fully_Classified_LAS LAS 1.2 files FEMA Guidelines and Specifications for Flood Hazard Mapping Partners, Appendix M: Data Capture Standards and Data Capture Guidelines (available at http://www.fema.gov/fhm/dl_cgs.shtm) Terrain\2149983\SupplementalData\Saline_Tile_Index Area Spatial File FEMA Guidelines and Specifications for Flood Hazard Mapping Partners, Appendix M: Data Capture Standards and Data Capture Guidelines (available at http://www.fema.gov/fhm/dl_cgs.shtm) Terrain\2149983\SupplementalData\Region 5 Saline Testing Results CVA Digital Document FEMA Guidelines and Specifications for Flood Hazard Mapping Partners, Appendix M: Data Capture Standards and Data Capture Guidelines (available at http://www.fema.gov/fhm/dl_cgs.shtm) Terrain\2149983\General\Saline_Product_Narrative Digital Document FEMA Guidelines and Specifications for Flood Hazard Mapping Partners, Appendix M: Data Capture Standards and Data Capture Guidelines (available at http://www.fema.gov/fhm/dl_cgs.shtm) The Terrain data package is made up of several data themes containing primarily spatial information.
