Abstract

These files contain rasterized topographic lidar elevations generated from returns classified as ground (2). These data were collected by the Compact Hydrographic Airborne Rapid Total Survey (CHARTS) system along the coast of Michigan. 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). Native lidar data is not generally in a format accessible to most Geographical Information Systems (GIS). Specialized in-house and commercial software processes the native lidar data into 3-dimensional positions that can be imported into GIS software for visualization and further analysis. The 3-D position data are used to generate a series of gridded file products, with each covering approximately 5 kilometers of shoreline.The data file naming convention is based on the year, project, area name, "Box" number and the product type. An example file name is "2009_NCMP_Isle_Royale_16TCT330995_BareEarth_1mGrid.tif", where 2009 is the year of data collection, NCMP is the project under which data were collected, Isle_Royale is the area of data collection, 16TCT330995 is the "Box" number and "BareEarth_1mGrid" is the product type.

In addition to these bare earth Digital Elevation Model (DEM) data, the lidar point data that these DEM data 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.
