Description: The Bismarck lidar project area covers approximately 395 square miles which includes a 100 meter buffer around the county boundary. The lidar data was acquired at a nominal point spacing (NPS) of 0.7 meters and a single swath nominal point density (NPD) of 2.0. Project specifications are based on Bismarck requirements and on the U.S. Geological Survey National Geospatial Program LiDAR Base Specification, Version 2.1. The data was developed based on a horizontal projection/datum of NAD83(HARN) / North Dakota South (Feet Intl), and vertical datum of NAVD88 - Geoid12A (Feet). LiDAR data was acquired using a Leica ALS 80 sensor with serial number 8239 from April 15, 2020 to April 17, 2020 in 4 total lifts. Acquisition occurred with leaves absent from deciduous trees, when no snow was present on the ground, and with rivers at or below normal levels.

Subject: This data, along with its derivatives, is the result of a countywide elevation mapping project through a cooperative partnership with the Bismarck-Mandan Metropolitian Planning Organization. This data was produced from lidar data collected in April 2020, which was processed and delivered in 2020.
