2007 US Army Corps of Engineers (USACE) National Coastal Mapping Program (NCMP) Topobathy Lidar - Michigan (Lake Huron shoreline)
This kmz file shows the extent of coverage for the 2007 USACE Michigan Lake Huron Topo/Bathy lidar data set.
This is a bare earth data set. The data contained in these files contain hydrographic and topographic data collected by the CHARTS system along the Lake Huron coast of Michigan from August 25 - September 26, 2007. The data were collected and processed in geographic coordinates and ellipsoid heights. The positions were relative to NAD83 in decimal degrees of longitude and latitude. The heights were converted from ellipsoid to orthometric heights (NAVD88) using the Geoid03 model with the results in meters. For data storage and provisioning purposes, the NOAA Coastal Services Center converted the data from NAVD88 heights to ellipsoid heights using GEOID03. CHARTS integrates topographic and bathymetric lidar sensors, a digital camera, and a hyperspectral scanner on a single remote sensing platform for use in coastal mapping and charting activities. Data coverage generally extends along the coastline from the waterline inland 500 meters (topography) and offshore 1,000 meters or to laser extinction (bathymetry). The topographic lidar sensor has a pulse repetition rate of 9 kHz at 1064 nm (near-infrared wavelength). The bathymetric lidar sensor has a pulse repetition rate of 1 kHz at 532 nm (green wavelength). Native lidar data is not generally in a format accessible to most Geographical 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.

These data covered the required survey area with minimal gaps in data coverage except boxes 16-27. There is no topo data covering these areas.
|Purpose:||These data were collected as a part of the National Coastal Mapping Program (NCMP) to depict the elevations above the water for the last return in the Michigan coastal zone.|
