In the fall of 2006, Sanborn Map Company was contracted by Camp Dresser McKee, Inc (CDM) to execute a LiDAR (Light Detection and Ranging) survey campaign in the state of Maine. LiDAR data in the form of 3-dimensional positions
of a dense set of masspoints was collected for the 584 sqaure miles of Cumberland and York Counties. This data was used in the development of the bare-earth-classified elevation point data sets. The Leica ALS-50 LiDAR system
was used to collect data for the whole survey campaign. The LiDAR system is calibrated by conducting flight passes over a known ground surface before and after each LiDAR mission. During final data processing, the calibration
parameters are inserted into post-processing software.
Six airborne GPS (Global Positioning System) base stations were used in this project. A new point was set at the Portland Airport (501) The other base stations were set up at National Geodetic Survey (NGS) markers. NGS Monuments
901- PID: OC0229 and 801 - PID: OC0230 are located at the Biddeford Airport. The other existing NGS monuments used in the network are point 701 - PID: AJ2697, located on Bailey Island, point 702 - PID: OC0429, located at Fort
Constitution, and point 703 - PID: OC0478 located southeast of York Beach were tied to the other three points to create a GPS survey network. The coordinates of these stations were checked against each other with the three
dimensional GPS baseline created at the airborne support set up and determined to be within project specifications.
Leica ALS-50 LiDAR Scanner Parameters:
Pulse Rate: 50,000 hertz
Scan Frequency: 36 hertz
Scan Width (Half Angle): 18 degrees
Flying Height: 1,200 meters above ground level
Flying Speed: ~120 knots
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
The LIDAR derived data sets, including Bare Earth and a Gridded DEM support Camp Dresser and McKee's continued development of updated Digital Flood Insurance Rate Maps and flood insurance studies for coastal areas
located in Cumberland and York Counties, Maine. Acquisition is Tide restricted to +/- 3 hours from Low tide.(Source: FEMA Guidelines and Specs, Appendix N).

Horizontal Positional Accuracy
The NSSDA is used to report the horizontal accuracy of the base map data used by FEMA to produce a FIRM. The NSSDA uses radial accuracy (Accuracy) to report the radius of a circle of uncertainty, such that the true or
theoretical location of a point falls within that circle 95 percent of the time. (Guidelines and Specifications Vol 1, p. 70)
; Quantitative Value: 1.0 meters, Test that produced the value: Value in meters. Project specifications require a horizontal accuracy of 1.0 meters. Data not tested but compiled to meet.
Vertical Positional Accuracy
The LiDAR data was evaluated by Sanborn using a collection of 24 GPS surveyed checkpoints. The data set's consolidated vertical accuracy is 0.165 meters (0.54 feet) RMSEz.; Quantitative Value: 0.165 meters, Test that produced the value: RMSEz in meters for all points.
Completeness Report
The NOAA Office for Coastal Management visually inspected the bounding boxes of each tile. The only void in the data set is a portion of tile 20071127_27801050.
Conceptual Consistency
Tests for logical consistency are performed by DFIRM tools topology verification software. The NOAA Office for Coastal Management checked the data set for logical consistency.
Using the Leica ALS-50 Light Detection and Ranging (LiDAR) system, flight lines were planned for standard density 1.4
meter GSD. The Flight plan for the project includes the following specifications to fully meet the project requirements - single pass
density of approximately 1.4 square meters per sample * Swath width ~688 meters * Flight altitude 1200 meters * flight line
spacing ~516 meters with ~125 meters overlap *Scan Frequency- 36 Hz *Scan Angle- 16 degrees * Aircraft ground speed -- 120
knots * System Calibration pre and post mission * Two GPS base stations within 30 KM. Multiple returns were recorded for each
laser pulse along with an intensity value for each return. The data are calibrated for geographic referencing. Points are further
processed, using TerraSolid software, to classify return values. The first and last return data is filtered to remove the vegetation
and above ground manmade features to yield a ground surface.

The NOAA Office for Coastal Management (OCM) received topographic files in LAS format. The files contained lidar
elevation and intensity measurements. The data were received in UTM Zone 19N (NAD83) coordinates
and were vertically referenced to NAVD88 using the Geoid03 model. The vertical units of the data were
meters. OCM performed the following processing for data storage and Digital Coast provisioning purposes:
1. The topographic las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid03.
2. The topographic las files were converted from a Projected Coordinate System (UTm 19N) to a Geographic Coordinate system (GCS).
3. The topographic las files' horizontal units were converted from meters to decimal degrees.
2013-04-01T00:00:00
The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 grids provided by the National Geodetic Survey.
Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org)
