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. purpose: Classified LAS files are used to show the manually reviewed bare earth surface. This allows the user to create Intensity Images, Breaklines and Raster DEM. The purpose of these lidar data was to produce high accuracy 3D hydro-flattened Digital Elevation Model (DEM) with a 2 foot cell size. These raw lidar point cloud data was used to create classified lidar LAS files, intensity images, 3D breaklines and hydro-flattened DEMs as necessary. credit: NRCS; USGS; Spicer Group Inc The custom download may be cited as National Oceanic and Atmospheric Administration (NOAA) Digital Coast Data Access Viewer.

The survey check points were distributed throughout the project area. The 68 independent check points (40 Spicer Group & 28 Kuchera) were surveyed using the closed level loop technique. Elevations from the classified lidar surface were measured for the x,y location of each check point. Elevations interpolated from the lidar surface were then compared to the elevation values of the surveyed control. The NVA RMSE was computed to be 0.181 international feet (5.52 cm). AccuracyZ has been tested to meet 19.6 cm Nonvegetated Vertical Accuracy at 95 percent confidence level using (RMSEz * 1.9600) as defined by the National Standards for Spatial Data Accuracy (NSSDA); assessed and reported using National Digital Elevation Program (NDEP)/ASPRS Guidelines. The NVA RMSE @ 95% confidence level was computed to be 0.355 international feet (10.82 cm). The VVA was tested using 44 independent surveys located in vegetated areas. The survey check points were distributed throughout the project area. The 44 independent check points were surveyed using the closed level loop technique. Elevations from the classified lidar surface were measured for the x,y location of each check point. Elevations interpolated from the lidar surface were then compared to the elevation values of the surveyed control. The VVA RMSE was computed to be 0.241 international feet (7.35 cm). AccuracyZ has been tested to meet 29.4 cm Vegetated Vertical Accuracy at the 95th percentile as defined by the National Standards for Spatial Data Accuracy (NSSDA); assessed and reported using National Digital Elevation Program (NDEP)/ASPRS Guidelines. The VVA RMSE @ the 95th percentile was computed to be 0.394 international feet (12.01 cm). result: (missing) report: (DQ_CompletenessCommission) nameOfMeasure: Completeness Report evaluationMethodDescription: These raw LAS data files include all data points collected.

Lidar ranging data were initially calibrated using previous best parameters for this instrument and aircraft. Relative calibration was evaluated using advanced plane-matching analysis and parameter corrections derived. This was repeated iteratively until residual errors between overlapping swaths, across all project lifts, was reduced to acceptable levels. Data were then block adjusted to match surveyed calibration control. Raw data NVA were checked using independently surveyed checkpoints. Swath overage points were identified and tagged within each swath file. The results of the final calibration, NVA and horizontal accuracy assessments, and the "raw" swaths were forwarded to the client to obtain a Notice To Proceed on classification and derivative product generation. dateTime: DateTime: 2018-01-01T00:00:00 processStep: (LI_ProcessStep) description: Classified LAS Processing: The bare earth surface is then manually reviewed to ensure correct classification on the Class 2 (Ground) points. After the bare-earth surface is finalized, it is then used to generate all hydro-breaklines through heads-up digitization. All ground (ASPRS Class 2) lidar data inside of the Lake Pond and Double Line Drain hydro flattening breaklines were then classified to water (ASPRS Class 9) using TerraScan macro functionality. All Lake Pond Island and Double Line Drain Island features were checked to ensure that the ground (ASPRS Class 2) points were reclassified to the correct classification after the automated classification was completed. All bridge decks were classified to Class 17. All overlap data was processed through automated functionality provided by TerraScan to classify the overlapping flight line data to approved classes by USGS. The overlap data was identified using the Overlap Flag, per LAS 1.4 specifications. All data was manually reviewed and any remaining artifacts removed using functionality provided by TerraScan and TerraModeler. dateTime: DateTime: 2018-01-01T00:00:00 processStep: (LI_ProcessStep) description: Hydro Flattening Breakline Processing: Class 2 lidar was used to create a bare earth surface model. The surface model was then used to heads-up digitize 2D breaklines of inland streams and rivers with a 100 foot nominal width and Inland Ponds and Lakes of 2 acres or greater surface area. Elevation values were assigned to all Inland Ponds and Lakes, Inland Pond and Lake Islands, Inland Stream and River Islands, using TerraModeler functionality. Elevation values were assigned to all Inland streams and rivers using ESRI Software. All ground (ASPRS Class 2) lidar data inside of the collected inland breaklines were then classified to water (ASPRS Class 9) using TerraScan macro functionality. The breakline files were then translated to ESRI File-Geodatabase format using ESRI conversion tools. dateTime: DateTime: 2018-01-01T00:00:00 processStep: (LI_ProcessStep) description: Hydro Flattened Raster DEM Process: Class 2 lidar in conjunction with the hydro breaklines were used to create a 1 foot Raster DEM. Using automated scripting routines within ArcMap, an ERDAS Imagine IMG file was created for each tile. Each surface is reviewed using ESRI ArcMAP to check for any surface anomalies or incorrect elevations found within the surface. dateTime: DateTime: 2018-01-01T00:00:00 processStep: (LI_ProcessStep) description: Intensity Image Generation Process: Image Generation Process: GeoCue software was used to create the deliverable Intensity Images. All overlap classes were ignored during this process. This helps to ensure a more aesthetically pleasing image. The GeoCue software was then used to verify full project coverage as well. TIF/TWF files were then provided as the deliverable for this dataset requirement. dateTime: DateTime: 2018-01-01T00:00:00 processStep: (LI_ProcessStep) description: Processing Boundary Creation: Processing boundary was created using original client-provided AOI shape file.
