Data Quality

Accuracy:

The Fundamental Vertical Accuracy (FVA) for the various project area achieved an RMSE of 0.185 meters or better.

Horizontal Positional Accuracy:

The horizontal accuracy of all the data sets is 1.0 meters or better, the point spacing is 1.3 meters or better.

Vertical Positional Accuracy:

The Fundamental Vertical Accuracy (FVA) of the Classified Bare Earth for all Areas achieved is 0.185 meters RMSEz (FVA) or better. For individual data sets the accuracies are as follow:

Arrowhead: 0.05m RMSEz (5cm) in open terrain

Twin Metro: .125m RMSEz (12.5cm) in open terrain, some areas as low as .09m RMSEz (9.0cm) in open terrain

Red River: .15m RMSEz (15cm) in open terrain

Southeast: .161m RMSEz (16.1cm) in open terrain

Central Lakes: .154m RMSEz (15.4cm)

Blue Earth County: .125m RMSEz (12.5cm) in open terrain

Chisago County: .0925m RMSEz (9.25cm) in open terrain

Crow Wing County: Unknown, flown to meet 2-foot contour specifications. Assumed accuracy of .185m RMSEz (18.5cm) or better

Pine County: .181m RMSEz (18.1cm) across 5 land cover classes

Wright County: Unknown, flown to meet 2-foot contour specifications. Assumed accuracy of .185m RMSEz (18.5cm) or better

Detailed accuracy information for these data sets may be found in the original documentation located here:

https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/1196/supplemental

; Quantitative Value: 0.185 meters, Test that produced the value:

Accuracy statement is based on the area of moderate to flat terrain. Diminished accuracies are to be expected in areas of dense vegetation. The accuracy of the LiDAR data as tested met the vertical accuracy or better, however,

derived products may be less accurate in areas of dense vegetation due to a lesser number of points defining the bare-earth in these areas.

Process Steps

Process Step 1

CC ID: 1132874
Description:

Lidar data processing by the collection firm and MNDNR varied for each data set. For more information, please refer to the detailed processing steps in the original documentation.

A copy of the original documentation for each record may be found here:

Process Date/Time: 2011-06-06 00:00:00

Process Step 2

CC ID: 1132875
Description:

The NOAA Office for Coastal Management (OCM) downloaded topographic files in .laz format from Minnesota's website in May, 2012 . The files contained lidar elevation measurements. The data were received

in UTM Zone 15N, NAD83 coordinates and were vertically referenced to NAVD88 using the appropriate Geoid03 or Geoid09. The vertical units of the data were meters. OCM performed the following processing for data storage

and Digital Coast provisioning purposes:

1. The topographic laz files were converted from a Projected Coordinate System (UTM Zone 15N) to a Geographic Coordinate system (NAD 83).

2. The topographic laz files' horizontal units were converted from meters to decimal degrees.

3. The topographic laz files' were converted from NAVD88 elevations to NAD83 ellipsoidal elevations using Geoid03 (Southeast, Red River Basin,Crow Wing County,Wright County, Chisago County, Pine County)

or Geoid09 (Blue Earth County,Central Lakes,Twin Cities Metro,Arrowhead).

4. If Classes 13, 17, 18 (Unknown) existed in the data, they were converted to Class 0 (Never Classified).

5. If Classes 14, 15 (Bridges) existed in the data, they were converted to Class 1 (Unclassified).
