Continental Mapping Consultants 20170730 Lidar point cloud The Federal Emergency Management Agency (FEMA) required high accruacy classified LiDAR data in combination with raster digital elevation models and hydrographic breaklines. For this effort, Continental Mapping Consultants (Continental) collected and processed high accuracy classified LiDAR data in .LAS format as well as a combination of raster digital elevation models.

N/A Unclassified N/A Environment as of Metadata Creation: Microsoft Windows 7 Professional; Esri ArcGIS 10.2.2; Microstation V8i Select Series 3 (version 8.11.09.459); TerraScan (version 016.001) Data cover the entire area specified for this project. These raw LAS data files include all data points collected. No points have been removed or excluded. A visual qualitative assessment was performed to ensure data completeness. No void areas or missing data exist. The raw point cloud is of good quality and data passes Nonvegetated Vertical Accuracy specifications. Flightlines included in this lift (170423) include line numbers: 20501, 20502, 20503, 20504, 20506, 20507, 20508, 20509, 20510, 20511, 20512, and 20513. The specifications require that only Nonvegetated Vertical Accuracy (NVA) can be computed for raw lidar point cloud swath files. The vertical accuracy was tested with 45 independent surveys located in open terrain. These check points were not used in the calibration or post processing of the lidar point cloud data. The survey check points were distributed throughout the project. Specifications for this project require that the NVA be 19.6 cm or better AccuracyZ at 95 percent confidence level. 0.100 meters AccuracyZ at 95 percent Confidence Interval The NVA was tested using 45 independent surveys located in open terrain. The survey check points were distributed throughout the project. The 45 independent check points were surveyed using the closed level loop technique. Elevations from the unclassified lidar surface were measured for the x,y location of each check point. Elevations interpolated from the lidar surface were then compared to the elevation values of the surveyed control. The RMSE was computed to be 0.051 meters. AccuracyZ has been tested to meet 10.0 cm Non-Vegetated Vertical Accuracy at 95 Percent confidence level using RMSE(z) x 1.9600 as defined by the National Standards for Spatial Data Accuracy (NSSDA); assessed and reported using National Digital Elevation Program (NDEP)/ASRPS Guidelines. 0.179 meters AccuracyZ at 95 percent Confidence Interval The VVA was tested using 35 independent surveys located in open terrain. The survey check points were distributed throughout the project. The 35 independent check points were surveyed using the closed level loop technique. Elevations from the unclassified lidar surface were measured for the x,y location of each check point. Elevations interpolated from the lidar surface were then compared to the elevation values of the surveyed control. The RMSE was computed to be 0.091 meters. AccuracyZ has been tested to meet 17.9 cm Vegetated Vertical Accuracy at 95 Percent confidence level using RMSE(z) x 1.9600 as defined by the National Standards for Spatial Data Accuracy (NSSDA); assessed and reported using National Digital Elevation Program (NDEP)/ASRPS Guidelines.

The base stations determine where LiDAR can be collected with the highest confidence of accuracy as determined by reading the same satellites in the aircraft and on the ground. Base stations typilcally are set at airports and provide coverage within 20 to 25 miles of the base if possible in order to cover in its entirety. Due to the timing constraints of weather and leaf off conditions requirement, and the high quality of the CORS network, the MIBC station located in Battle Creek and the MICW station located in Coldwater were used for this project. Both stations collect a 1 second sampling rate and are maintained by the Michigan Department of Transportation. The purpose of boresighting is to determine the offset values for the IMU used in the LiDAR sensor. To determine the boresight offset values, the LiDAR sensor has to be flown in a certain configuration over a well-controlled site. The boresighting is done both prior to the flight of the project area and after. This insures that the quality of the LiDAR was maintained throughout the process. 5017_Calhoun_MI_Control.csv 2016 Compass Data Inc. N/A mailing and physical

Centennial CO 80112 USA 303-627-4058 The aerial survey teams were deployed at the first opportunity based on availability of acceptable weather conditions. Due to snow cover and lake effect precipitation, the flight was delayed until April. Leica’s AeroPlan software was utilized to conduct the final flight planning. The sensor used was a Leica ALS70, which is owned and operated by Kucera International. There were 37 project flight lines, and 1 cross flight collected. The LiDAR acquisition started on April 18, 2017 in which one lift was achieved. Due to weather concerns, two aircraft were initially deployed. Due to sensor complications, a re-flight of the northern portion of the county was performed 5 days later on April 23, 2017 in which two lifts were achieved. Altitude: 7500 feet Aircraft Ground Speed: 150 knots Pulse Rate: 263.2 kHz Scan Rate: 48.1 Hz Full Field of View: 38 degrees Multi-Pulse: Yes Full Swath Width: 4650 meters Swath Overlap: 20% Average Point Density: 2.3 pts/m^2 Solar activity reached low levels on 17-18 Apr due to isolated C-class flare activity from Region 2651 (N12, L= 070, class/area=Cso/150 on 23 Apr), but solar activity was at very low levels through the remainder of the period (19-23 Apr). 5017_Calhoun_MI_Control.csv 2017 Kucera International Inc.
