Service Description: Maine GeoLibrary LiDAR Project. Geographic Extent: Central Maine, covering approximately 2,882 total square miles. Dataset Description: The Maine and Massachusetts 2015 QL1 and QL2 LiDAR project called for the Planning, Acquisition, processing and derivative products of LIDAR data to be collected at an aggregate nominal pulse spacing (NPS) of 0.7 meters for the 2,882 sqmi of the QL2 Maine AOI. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base LIDAR Specification, Version 1.2. The data was developed based on a horizontal projection/datum of NAD83 (2011) UTM Zone 19, meters and vertical datum of NAVD1988 (GEOID12A), meters. LiDAR data was delivered in RAW flight line swath format, processed to create Classified LAS 1.4 Files formatted to 3,585 individual 1,500 meter X 1,500 meter tiles. Corresponding 1-meter Intensity Image and 1-meter Bare Earth DEM tiles were created with the same 1,500 meter X 1,500 meter tile schema. Breaklines were produced in Esri shapefile format. Ground Conditions: LiDAR was partially collected in spring of 2015 and completed in winter 2015, 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, Quantum Spatial established a total of 286 Land Cover control points. These were used to calibrate the LIDAR to known ground locations established throughout the entire Maine UTM 19 QL2 project area (136 calibration control points and 150 QC checkpoints).
