Ayres Associates unknown The project established topographic mapping to 1-foot interval contours using LiDAR (Light Detection and Ranging) for the Bismarck-Mandan Metropolitan Planning Organization (MPO). The MPO is comprised of the City of Bismarck, City of Mandan, City of Lincoln, and portions of Burleigh and Morton Counties in North Dakota. The LiDAR data was collected on 20160326 through 20130328 using the Orion Optech H300 sensor. Nominal point spacing for the raw (unprocessed) LiDAR point cloud is approximately 0.7-meter, resulting in a nominal point density of 2 points per square meter. Aerial LiDAR survey data acquisition was conducted with the ground is free of snow, and with the atmospheric conditions between the aircraft and the ground free of clouds and fog. Aerial LiDAR survey data acquisition is flown with an average of 30% overlap between swaths. The primary target area is the Bismarck-Mandan Metropolitan Planning Organization (MPO) and vicinity (approximately 400 square miles). The project will successfully provide leaf-off DEM geo-referenced digital orthoimagery of the project area as defined by the MPO. The purpose of the MPO, a certified planning entity in the State of North Dakota, is to provide a forum for public officials, citizens, and other interested groups to establish policies and plans for effectively addressing various metropolitan transportation issues. The MPO has a planning process that supports metropolitan community development and social goals. These plans and programs shall lead to the development of an integrated, inter-modal metropolitan transportation system that facilitates the efficient, economic movement of people and goods. n/a Optech Orion H300 4 0.69 0.69 2.10 2.10 975 115 30 42.5 75 4 0.41 1064 0 0.25 523 25 NAD 1983 HARN StatePlane North Dakota South FIPS 3302 Feet Intl North American Vertical Datum 1988 (Geoid 12A) n/a n/a n/a n/a n/a n/a n/a 1.4 6 Class 11 Swath overage points deemed unreliable to be included in the standard deliverable classifications 16 1 Processed, but unclassified 2 Bare-earth ground 5 High Vegetation 6 Building 7 Low noise 9 Water 10 Ignored Ground 11 Withheld 17 Bridge Decks 18 High noise 20160326 20160328 ground condition Complete None planned -101.093572 -100.582052 46.983863 46.652896 None elevation data Lidar classification None Bismarck Mandan Lincoln City Burleigh Morton County North Dakota Any and all accessibility to data of or pertaining to the 2016 lidar dataset is to be determined by the Bismarck-Mandan Metropolitan Planning Organization (MPO).

Spatial consistency of coverage of the Bismarck-Mandan MPO 2016 project area was maintained throughout the dataset. A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. Vertical accuracy meets or exceeds an RMSEz of 0.31 international feet. LiDAR processing utilizes several software packages, including GeoCue and the TerraSolid suite of processing components. The GeoCue software is a database management system for housing the LiDAR dataset (usually multiple gigabytes in size). GeoCue incorporates a thorough checklist of processing steps and quality assurance/quality control (QA/QC) procedures that assist in the LiDAR workflow. The TerraSolid software suite is used to automate the initial classification of the LiDAR point cloud based on a set of predetermined parameters. Lidar technicians refer to ground cover research (natural and cultural features) within the project area and determine algorithms most suitable for the initial automated LiDAR classification. (Some algorithms/filters recognize the ground in forests well, while others have greater capability in urban areas). During this process each point is given an initial classification (e.g., as ground, vegetation, or noise) based on the point's coordinates and the relation to its neighbors. Classifications to be assigned include all those outlined by ASPRS standards. The initial classifications produce a coarse and inexact dataset, but offer an adequate starting point for the subsequent manual classification procedure. During this step, "overlap" points are automatically classified (those originating from neighboring flightlines) using information gathered from the ABGPS and IMU data. Any duplicate points existing from adjacent flightlines are removed during this process. Hydrographic breaklines are collected using LiDARgrammetry to ensure hydroflattened water surfaces. This process involves manipulating the LiDAR data's intensity information to create a metrically sound stereo environment. From this generated "imagery", breaklines are photogrammetrically compiled. Breakline polygons are created to represent open water bodies. The LiDAR points that fall within these areas are classified as "water." All hydrographic breaklines include a 1.5 foot buffer, with the Class 2 (bare earth) points being re-classified as Class 10 (ignored ground). TerraSolid is further used for the subsequent manual classification of the LiDAR points allowing technicians to view the point cloud in a number of ways to ensure accuracy and consistency of points and uniformity of point coverage. A triangulated irregular network (TIN) model was created from the Bare Earth LAS and breaklines. The TIN was processed to create one foot contours.
