Geographic Extent: Seven counties in New York. East Zone AOI is Franklin and St. Lawrence Counties, Central Zone AOI is Lewis, Madison, Oneida, Onondaga, and Oswego Counties. Dataset Description: New York FEMA 2016 QL2 Lidar project called for the planning, acquisition, processing, and derivative products of lidar data to be collected at a nominal pulse spacing (NPS) of 0.7 meters. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification, Version 1.2. Lidar data was delivered as flightline-extent unclassified LAS swaths, as processed classified LAS 1.4 files formatted to 4,597 individual 1,500-meter x 1,500-meter tiles, as tiled intensity imagery, and as tiled bare earth DEMs; all tiled to the same 1,500-meter x 1,500-meter schema. Continuous breaklines were produced in Esri file geodatabase format. Contours with a 1-foot interval were produced in Esri file geodatabase format, tiled to the same 1,500-meter x 1,500-meter schema. Ground Conditions: Lidar was collected in winter/spring of 2016/2017, while no snow was on the ground and rivers were at or below normal levels. In order to post process the lidar data to meet task order specifications and meet ASPRS vertical accuracy guidelines, Quantum Spatial, Inc. established a total of 76 ground control points that were used to calibrate the lidar to known ground locations established throughout the New York East Zone (Franklin and St. Lawrence Counties) project area. An additional 71 independent accuracy checkpoints, 71 in Bare Earth and Urban landcovers (59 NVA points), 59 in Forested, Brushland/Trees, and Tall Weeds/Crops categories (59 VVA points), were used to assess the vertical accuracy of the data. Quantum Spatial, Inc. established a total of 30 ground control points that were used to calibrate the lidar to known ground locations established throughout the New York Central Zone (Lewis, Madison, Oneida, Onondaga, and Oswego Counties) project area. An additional 64 independent accuracy checkpoints, 41 in Bare Earth and Urban landcovers (41NVA points), 23 in Forested, Brushland/Trees, and Tall Weeds/Crops categories (25 VVA points), were used to assess the vertical accuracy of the data. These checkpoints were not used to calibrate or post process the data. The NOAA Office for Coastal Management (OCM) downloaded the 4597 las files from the New York State GIS site. The data for Frankin and St. Lawrence Counties were downloaded from this URL: ftp://ftp.gis.ny.gov/elevation/LIDAR/FEMA_FranklinStLawrence2016/. The data for the Oneida Sub-Basin area (1351 laz files) were downloaded from the USGS ftp site: ftp://rockyftp.cr.usgs.gov/vdelivery/Datasets/Staged/Elevation/LPC/Projects/USGS_LPC_NY_FEMA_R2_B1_2016_LAS_2018/laz/. The data were processed to the Data Access Viewer (DAV) and https.

The required accuracy (ACCz) is: 19.6 cm at a 95% confidence level, derived according to NSSDA, i.e., based on RMSE of 10 cm in the "bare earth" and "urban" land cover classes. The NVA was tested with 71 checkpoints located in bare earth and urban (non-vegetated) areas. These check points were not used in the calibration or post processing of the lidar point cloud data. The checkpoints were distributed throughout the project area and were surveyed using GPS techniques. See survey report for additional survey methodologies. 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 points. AccuracyZ has been tested to meet 19.6 cm or better Non-Vegetated Vertical Accuracy at 95% 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 NVA of the raw lidar point cloud swath files was calculated against TINs derived from the final calibrated and controlled swath data using 71 independent checkpoints located in Bare Earth and Urban land cover classes. Tested 0.0864 meters NVA at a 95% confidence level (4.41 cm NVA RMSE) using RMSE(z) x 1.9600 as defined by the National Standards for Spatial Data Accuracy (NSSDA). Central Zone (Lewis, Madison, Oneida, Onondaga, Oswego Counties) The project specifications require that only Non-Vegetated Vertical Accuracy (NVA) be computed for raw lidar point cloud swath files. The required accuracy (ACCz) is: 19.6 cm at a 95% confidence level, derived according to NSSDA, i.e., based on RMSE of 10 cm in the "bare earth" and "urban" land cover classes. The NVA was tested with 41 checkpoints located in bare earth and urban (non-vegetated) areas. These check points were not used in the calibration or post processing of the lidar point cloud data. The checkpoints were distributed throughout the project area and were surveyed using GPS techniques. See survey report for additional survey methodologies. Elevations from the unclassified lidar surface were measured for the x,y location of each check point.

Completeness Report All files are inspected to ensure that they conform to the specified file naming conventions, all files load in their correct geographic position, all files conform to the project specifications for file standard and content. These 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 Non-Vegetated Vertical Accuracy specifications. Conceptual Consistency Data covers the entire area specified for this project. Data were collected and processed by Quantum Spatial, Inc. for FEMA. The data were downloaded from the New York State GIS ftp site and the USGS ftp site by the NOAA Office for Coastal Management (OCM) where the data were processed to make it available for custom download from the Data Access Viewer (DAV) and bulk download from https. LAS Point Classification: The point classification is performed as described below. The bare earth surface is then manually reviewed to ensure correct classification on the Class 2 (Ground) points. After the bare-earth surface is finalized, it is then used to generate all hydro-breaklines through heads-up digitization. All ground (ASPRS Class 2) lidar data inside of the Lake Pond and Double Line Drain hydro-flattened breaklines were then classified to Water (ASPRS Class 9) using TerraScan macro functionality. A buffer of 1 meter was also used around each hydro-flattened feature to classify these ground (ASPRS Class 2) points to Ignored ground (ASPRS Class 10). All Lake Pond Island and Double Line Drain Island features were checked to ensure that the ground (ASPRS Class 2) points were reclassified to the correct classification after the automated classification was completed. All overlap data was processed through automated functionality provided by TerraScan to classify the overlapping flight line data to approved classes by USGS. The overlap data was classified using standard LAS overlap bit. These classes were created through automated processes only and were not verified for classification accuracy. Due to software limitations within TerraScan, these classes were used to trip the withheld bit within various software packages. These processes were reviewed and accepted by USGS through numerous conference calls and pilot study areas. All data was manually reviewed and any remaining artifacts removed using functionality provided by TerraScan and TerraModeler. Global Mapper us used as a final check of the bare earth dataset. GeoCue was then used to create the deliverable industry-standard LAS files for both the All Point Cloud Data and the Bare Earth. Quantum Spatial, Inc. proprietary software was used to perform final statistical analysis of the classes in the LAS files, on a per tile level to verify final classification metrics and full LAS header information. 2017-01-01T00:00:00 The NOAA Office for Coastal Management (OCM) downloaded 4597 las files from ftp://ftp.gis.ny.gov/elevation/LIDAR/FEMA_FranklinStLawrence2016/.
