Geographic Extent: Saginaw County, MI, covering approximately 815 square miles. Dataset Description: This data was part of a joint project between USDA Natural Resources Conservation Service (NRCS), USGS, and the state of Michigan to collect 31 counties of Michigan in 2016. Though the overall project has 2016 in the name, this Saginaw County data was collected in 2015. The Saginaw collection 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 1.0. The data was developed based on a horizontal projection/datum of Michigan State Plane South, NAD83, international feet and vertical datum of NAVD1988 (GEOID12A), international feet. Lidar data was delivered in RAW flight line swath format, then processed to create Classified LAS 1.2 Files formatted to 991 individual 5000 foot X 5000 foot tiles. Corresponding Intensity Images and Bare Earth DEMs tiles were created with the same 5000 foot X 5000 foot tile schema. Breaklines were produced in Esri geodatabase format. Processing by NOAA for ingest into the Digital Coast Data Access Viewer changed the projection and datum to NAD83(2011) ellipsoid heights in meters with geographic coordinates in the cloud optimized point cloud version of LAZ. Ground Conditions: Lidar was collected in spring of 2015, 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, Spicer Group Inc established a total of 120 Land Cover control points (52 QC checkpoints, 68 calibration control points) which were used to calibrate the Lidar to known ground locations established throughout the Saginaw County, MI project area. 28 additional check points were surveyed by Kucera for the accuracy check of the initial acquisition. these 28 points have been added to the NVA Lidar and DEM accuracy reports. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
