These files were collected for the USACE New England District (NAE). The files include 13 separate project areas. These areas are named: Bar Harbor, Criehaven and Matinicus Harbor, Kennebec-Swan Island, Kennebec-Training Wall, Kennebunk River, Lubec Channel, Moosabec Reach, Portland Harbor, Richmond Island, Rockland Harbor, Saco River, Scarborough River, and Wells Harbor. The dates of collection for each project are as follows: Bar Harbor (20141110), Criehaven and Matinicus Harbor (20141111-20141113), Kennebec-Swan Island (20141113), Kennebec-Training Wall (20141113), Kennebunk River (20141111), Lubec Channel (20141115), Moosabec Reach (20141115), Portland Harbor (20141109-20141111), Richmond Island (20141109-20141111), Rockland Harbor (20141111-20141113), Saco River (20141110-20141115), Scarborough River (20141109-20141111), Wells Harbor (20141111). These files contain classified topo/bathy lidar data. Data are classified as 1 (valid non-ground topographic data), 2 (valid ground topographic data), and 29 (valid bathymetric data). Classes 1 and 2 are defined in accordance with the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards. These data were collected by the Coastal Zone Mapping and Imaging Lidar (CZMIL) system. CZMIL integrates a lidar sensor with simultaneous topographic and bathymetric capabilities, a digital camera and a hyperspectral imagery on a single remote sensing platform for use in coastal mapping and charting activities. Native lidar data is not generally in a format accessible to most Geographic Information Systems (GIS). Specialized in-house and commercial software packages are used to process the native lidar data into 3-dimensional positions that can be imported into GIS software for visualization and further analysis. In addition to these lidar point data, the bare earth Digital Elevation Models (DEM) created from the lidar point data are also available. These data are available for custom download at the link provided in the URL section of this metadata record. These products have not been reviewed by the NOAA Office for Coastal Management and any conclusions drawn from the analysis of this information are not the responsibility of NOAA or the Office of Coastal Management (OCM). This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
