Two Foot Contour

Data collected between 3/29/17 and 5/3/17. Contours created on 12/13/18. The 1-foot elevation contours were presented as a feature class in an Esri ArcGIS 10.3 File Geodatabase. The contours were derived from Bare-Earth (DEMs) created from QL2 LiDAR data. Source Data Description: MI 2016 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 1.2. The data was developed based on a horizontal projection/datum of Michigan State Plane South, NAD83(2011), international feet and vertical datum of NAVD1988 (GEOID12A), international feet. Deliverables included classified LAS, Raw LAS, Bare-Earth hydro-flattened DEMs, Breaklines and Intensity images. Ground Conditions: LiDAR was collected in spring or fall, while no snow was on the ground and rivers were at or below normal levels.
