Unpublished Material Digital Image File .IMG Albany, NY None Available Atlantic Axis Geospatial has contracted Atlantic to obtain professional services related to the development of Light Detection and Ranging (LiDAR) data between April 2015 and June 2015. This data set is consisting of LiDAR Point Cloud, Classified LiDAR, Digital Elevation Model, and LiDAR Intensity Images which all pieces encompasses the entire 2,424 Square miles (6,278 km)of the NY_WarrenWashingtonEssex_Spring2015 project area. The project area spans 5 counties including Warren, Washington, Essex, Hamilton, and Franklin. This data set consists of LiDAR point cloud with nominal pulse spacing of 0.5557m, LAS swath files (249), and tiled Las files. Each LAS file contains LiDAR point information, which has been calibrated, controlled, and classified. Each file represents a separate swath of LiDAR. Ground Conditions: water at normal levels; no unusual inundation; no snow; leaf off The calibrated point cloud data from the laser sensor was merged to produce processed (*.las) files including but not limited to 3D position, intensity, and time-stamp. A filtering methodology was utilized to produce a multi-return surface elevation model dataset with bare-earth conditions. GeoCue, TerraScan, and TerraModel software was used for the initial batch processing and manual editing of the (*.las) point clouds. The errors (noise columns) in classification were corrected by identifying the areas of dense noise in the point cloud and manually removing the incorrectly classified ground surfaces and above ground features.The Withheld and Overlap flags were utilized for the final LAS v1.4 file production. These classified LiDAR points were then used in the creation of other deliverables such as Bare-Earth Digital Elevation Models (DEMs) and LiDAR Intensity images.The final deliverables are in UTM and includes 2783 tiles. How the Withheld Points are Identified: Withheld (ignore) points were identified in the files using the standard LAS Withheld bit. Class Code:0 Class Item: Never Classified Class Code:1 Class Item: Undetermined/Unclassified Class Code:2 Class Item: Ground Class Code:7 Class Item:Low Point (Noise) Class Code:17 Class Item:Bridge Deck Class Code:18 Class Item:High Noise This LiDAR elevation data and its derivatives including high resolution Bare Earth DEMs and LiDAR Intensity imagery will be used for conservation planning, design, research, floodplain mapping, wetlands identification, dam safety assessments, hydrologic modelling, subsidence monitoring, and general spatial analyst. All Lidar data was acquired, calibrated, and used in the creation of Lidar derived products by Atlantic. 201504290800201505230800 ground condition Complete As needed -74.561953 -73.201550 44.297386 43.339153 535500.00 643500.00 4905000.00 4800000.00 None Elevation Data LiDAR DEM Intensity Image None New YorkWarrenEssexWashingtonHamiltonFranklinAdirondack No restrictions apply to this data the data represented is the result of data collection and processing per contract specifications and indicates the general existing conditions at the time of the data collection.

All DEM tiles show no edge artifacts or mismatches from tile to tile. Void areas (i.e., areas outside the project boundary but within the tiling scheme) are coded using a unique NODATA value. This value is identified in the appropriate location within the file header. Data cover the entire area specified for this project. The raw LAS data files included 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 Fundamental Vertical Accuracy specifications.Void areas (i.e., areas outside the project boundary but within the tiling scheme) are coded using a unique NODATA value. This value is identified in the appropriate location within the file header. Vertical Accuracy of the point cloud and bare-earth lidar data was assessed and reported in accordance with the ASPRS Positional Accuracy Standards for Digital Geospatial Data; Six-Hundred and Seventy-Three (673) surveyed points were measured for the purpose of assessing the accuracy of the NY_WarrenWashingtonEssex_Spring2015 project data. (294 NVA + 379 VVA). 0.077 m This DEM data set was tested to meet ASPRS Positional Accuracy Standards for Digital Geospatial Data (2014) for a 10.0(cm) RMSEz Vertical Accuracy Class. Actual NVA accuracy of the bare-earth DEMs was found to be RMSEz = 0.77 m, equating to +/- 0.152 m at 95% confidence level. 0.099 m This DEM data set was tested to meet ASPRS Positional Accuracy Standards for Digital Geospatial Data (2014) for a 10.0 (cm) RMSEz Vertical Accuracy Class. Actual VVA accuracy was found to be RMSEz = 0.099 m, equating to +/- 0.178 m at 95% confidence level. Horizontal error in lidar derived elevation data is largely a function of positional error as derived from the Global Navigation Satellite System (GNSS), attitude (angular orientation) error (as derived from the INS) and flying altitude; and can be estimated based on these parameters. 0.130 m As described in Section 7.5 of the ASPRS Positional Accuracy Standards for Digital Geospatial Data the horizontal errors in lidar data are largely a function of GNSS positional error, INS angular error, and flying altitude. Therefore lidar data collected with GNSS error of 0.05m and the IMU error of 0.03492 degrees at an altitude of 2300m; the expected radial horizontal positional error will be RMSEr = 0.130 m.

LiDAR ranging data were initially calibrated using previous best parameters for this instrument and aircraft. Relative calibration was evaluated using advanced plane-matching analysis and parameter corrections derived. This process was repeated interactively until residual errors between overlapping swaths, across all project lifts, was reduced to 2 cm or less. Data was then block adjusted to match surveyed calibration control. Raw data NVA was checked using independently surveyed check points. Swath overage points were identified and tagged within each swath file. 20150601 0800 NY_WarrenWashingtonEssex_Acq_05_02_ANY_WarrenWashingtonEssex_Acq_05_03_ANY_WarrenWashingtonEssex_Acq_05_05_ANY_WarrenWashingtonEssex_Acq_05_05_BNY_WarrenWashingtonEssex_Acq_05_06_ANY_WarrenWashingtonEssex_Acq_05_06_BNY_WarrenWashingtonEssex_Acq_05_06_CNY_WarrenWashingtonEssex_Acq_05_07_ANY_WarrenWashingtonEssex_Acq_05_07_BNY_WarrenWashingtonEssex_Acq_05_07_CNY_WarrenWashingtonEssex_Acq_05_07_DNY_WarrenWashingtonEssex_Acq_05_23_ANY_WarrenWashingtonEssex_Acq_04_29_ANY_WarrenWashingtonEssex_Acq_04_29_BNY_WarrenWashingtonEssex_Acq_04_29_CNY_WarrenWashingtonEssex_Acq_04_30_A AtlanticChris CannonAssociate Vice President Production Managermailing and physical address

This type of noise is only present in the SN7123 ALS70 sensor acquired data in the southern half of the project area. A combination of the acquisition discriminator settings, flying height, FOV, terrain, and surface reflectance were the cause of these occurrences. In these instances the scanner’s nadir position (scanner nadir as opposed to the center of the acquired swath) in correlation to the planar surface of a roof or waterbody exhibited a bias in the digitized intensity from the low-gain channels. As the laser output is scanned through the point where the laser output is perpendicular to the roof or water surface with very low reflectance the increased sensitivity from the acquisition discriminator settings resulted in an increase of laser backscatter reflected into the receiver. That backscatter was represented as columns of erroneous points or noise, while this did not affect the laser returns at ground level it did effect the automated high noise filtering in the initial classification process.201506150800NY_WarrenWashingtonEssex_Acq_05_02_ANY_WarrenWashingtonEssex_Acq_05_03_ANY_WarrenWashingtonEssex_Acq_05_05_ANY_WarrenWashingtonEssex_Acq_05_05_BNY_WarrenWashingtonEssex_Acq_05_06_ANY_WarrenWashingtonEssex_Acq_05_06_BNY_WarrenWashingtonEssex_Acq_05_06_CNY_WarrenWashingtonEssex_Acq_05_07_ANY_WarrenWashingtonEssex_Acq_05_07_BNY_WarrenWashingtonEssex_Acq_05_07_CNY_WarrenWashingtonEssex_Acq_05_07_DNY_WarrenWashingtonEssex_Acq_05_23_ANY_WarrenWashingtonEssex_Acq_04_29_ANY_WarrenWashingtonEssex_Acq_04_29_BNY_WarrenWashingtonEssex_Acq_04_29_CNY_WarrenWashingtonEssex_Acq_04_30_A Atlantic Chris Cannon Associate Vice President Production Manager mailing and physical address

The solution file was generated and CloudPro software was used to generate georeferenced laser returns which were then processed in strip form allowing for the QC of the overlap between strips (lines). The data from each line were combined and automated classification routines run to determine the initial surface model. This initial surface model was then verified to the surveyed test points. 20150601 0800 NY_WarrenWashingtonEssex_Acq_05_02_ANY_WarrenWashingtonEssex_Acq_05_03_ANY_WarrenWashingtonEssex_Acq_05_05_ANY_WarrenWashingtonEssex_Acq_05_05_BNY_WarrenWashingtonEssex_Acq_05_06_ANY_WarrenWashingtonEssex_Acq_05_06_BNY_WarrenWashingtonEssex_Acq_05_06_CNY_WarrenWashingtonEssex_Acq_05_07_ANY_WarrenWashingtonEssex_Acq_05_07_BNY_WarrenWashingtonEssex_Acq_05_07_CNY_WarrenWashingtonEssex_Acq_05_07_DNY_WarrenWashingtonEssex_Acq_05_23_ANY_WarrenWashingtonEssex_Acq_04_29_ANY_WarrenWashingtonEssex_Acq_04_29_BNY_WarrenWashingtonEssex_Acq_04_29_CNY_WarrenWashingtonEssex_Acq_04_30_A LiDAR Post-Processing: The calibrated and controlled LiDAR swaths were processed using automatic point classification routines in TerraSolid software. These routines operate against the entire collection (all swaths, all lifts), eliminating character differences between files. Data were then distributed as virtual tiles to experienced LiDAR analysts for localized automatic classification, manual editing, and peer-based QC checks. Supervisory QC monitoring of work in progress and completed editing ensured consistency of classification character and adherence to project requirements across the entire project. All classification tags are stored in the original swath files. After completion of classification and final QC approval, the NVA and VVA for the project are calculated. Sample areas for each land cover type present in the project were extracted and forwarded to the client, along with the results of the accuracy tests. Upon acceptance, the complete classified LiDAR swath files were delivered to the client. Atlantic Chris Cannon Associate Vice President/ Production Manager mailing and physical address
