This metadata record describes the Classified Point Cloud for the 2019 19 County FEMA Michigan LiDAR project. The data collection was funded by NRCS and USGS and the State of Michigan was in charge of collection. Nineteen counties (some with only partial coverage) were collected in total.
Product: These lidar data are processed Classified LAS 1.4 files, formatted to individual 2500 ft x 2500 ft tiles; used to create intensity images, 3D breaklines and hydro-flattened DEMs as necessary.
Dataset Description: The FEMA 19 County, Michigan 2019 Lidar project called for the Planning, Acquisition, processing and derivative products of lidar data to be collected at a nominal pulse spacing (NPS) of 0.7 meter. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification, Version 1.3. The data was developed based on a horizontal projection/datum of NAD83 (2011), State Plane Coordinate System, international feet and vertical datum of NAVD88 (GEOID12B), international feet. Lidar data was delivered as processed Classified LAS 1.4 files, formatted to individual 2500 ft x 2500 ft tiles, as tiled Intensity Imagery, and as tiled bare earth DEMs; all tiled to the same 2500 ft x 2500 ft schema.
Ground Conditions: Lidar was collected in spring 2019, 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 and meet ASPRS vertical accuracy guidelines, Sanborn Map Company, Inc. established ground control points that were used to calibrate the lidar to known ground locations established throughout the project area. Additional independent accuracy check points in Open Terrain/Bare-Earth and Urban landcovers, in Grass, Brush and Trees categories were used to assess the vertical accuracy of the data. These check points were not used to calibrate or post process the data.
The NOAA Office for Coastal Management (OCM) downloaded laz files from this USGS site and processed the data to the Data Access Viewer (DAV) and to https:
ftp://rockyftp.cr.usgs.gov/vdelivery/Datasets/Staged/Elevation/LPC/Projects/MI_FEMA_2019_C19/
Counties included: Alcona, Alpena, Antrim, Cheboygan, Chippewa, Crawford, Dickinson, Gogebic, Houghton, Iron, Kalkaska, Keweenaw, Luce, Menominee, Montmorency, Ontonagon, Oscoda, Ostego, and Schoolcraft.
