USGS Contract Number: G10PC00026

USGS Task Order: G10PD01737

LiDAR was collected at a 1.0 points per square meter (1.0m GSD) for the county of Androscoggin, Maine while no snow was on the ground and rivers were at

or below normal levels and prior to leaf-on conditions.

In addition to these bare earth Digital Elevation Model (DEM) data, the lidar point data that these DEMs were created from, are also available. These data are available for custom download at the link provided in the URL section of this metadata record.

Hydro breaklines are also available. These data are available for download at the link provided in the URL section of this metadata record. Please note that these products have not been reviewed by the NOAA Office for Coastal Management (OCM) and any conclusions drawn from the analysis of this information are not the responsibility of NOAA or OCM.
* Purpose

One meter point spacing LiDAR data collection provides the information to create Intensity Images, Break Lines, Raster DEMs, and fully Classified LiDAR LAS files.

The project area requires LiDAR to be collected on average of 1 meter point spacing or better and vertical accuracy of 18.0 centimeters RMSE or better to support 2' contour generation when combined with breaklines.
Analytical Accuracy
Horizontal Positional Accuracy
Vertical Positional Accuracy

Deliverables were tested by Photo Science for both vertical and horizontal accuracy. All data is seamless from one tile to the next, no gaps or no data areas.

The vertical unit of the data file is in meters.

Process Steps

Process Step Number 1
» Description

Leica software was used in the post processing of the airborne GPS and inertial data that is critical to the positioning of the sensor during all flights. This software suite includes Applanix's PosPac and Waypoint's GrafNav solutions. PosPac provides the smoothed best estimate of trajectory (SBET) that is necessary for Leica's post processor to develop the point cloud from the LiDAR missions. The point cloud is the mathematical three dimensional collection of all returns from all laser pulses as determined from the aerial mission. At this point this data is ready for analysis, classification, and filtering to generate a bare earth surface model in which the above ground features are removed from the data set.

The point cloud was manipulated within the Leica software; GeoCue, TerraScan, and TerraModeler software was used for the automated data classification, manual cleanup, and bare earth generation from this data. Project specific macros were used to classify the ground and to remove the side overlap between parallel flight lines.

All data was manually reviewed and any remaining artifacts removed using functionality provided by TerraScan and TerraModeler.

Buffered LAS files were created in GeoCue to provide overedge to the DEM creation. These tiles were then run through automated scripting within ArcMap and were combined with the Hydro Flattened Breaklines to create the 2.5 foot DEM. Final DEM tiles were clipped to the tile boundary to provide a seamless dataset.

ERDAS IMG files were then created as the project deliverable.

A manual QA review of the tiles was completed in ArcMap and Global Mapper to ensure full coverage with no gaps or slivers within the project area.

The NOAA Office for Coastal Management (OCM) received 648 raster files. The data were in Maine State Plane West (NAD83) coordinates and NAVD88 (Geoid03) elevations in feet. The bare earth raster files were at a 2.5 ft grid spacing.

OCM performed the following processing on the data for Digital Coast storage and provisioning purposes:

1. Converted the files from img format to cloud optimized GeoTiff format.
