These data were created as part of the National Oceanic and Atmospheric Administration Office for Coastal Management's efforts to create an online
mapping viewer depicting potential water level increase and decrease in the coastal areas of the Great Lakes. The lakes included are:
Erie, Huron, Michigan, Ontario, St. Clair, and Superior. The purpose of the mapping viewer is to provide coastal managers and scientists with a
preliminary look at lake level change and potential coastal impacts. The viewer is a screening-level tool that uses nationally consistent data sets and
analyses to help users examine multiple scenarios and prioritize actions. The Lake Level Viewer may be accessed at:
https://coast.noaa.gov/llv
These data depict the mapping confidence of the associated lake water level data for the water level amounts of -6 feet through +6 feet. The mapping
process is designed to give the most accurate picture of water extent possible, but inherent data errors introduce some uncertainty in the exact water
extents. The presentation of data confidence only represents the known error in the elevation data and not uncertainty associated with the natural evolution
of the coastal landforms (e.g., erosion or bluff failure) or future climate change impacts on lake levels.
To access the associated data to be used with this data:

https://coast.noaa.gov/llv
The NOAA Office for Coastal Management has tentatively adopted an 80 percent rank (as either inundated or not inundated) as the zone of relative confidence.
The use of 80 percent has no special significance but is a commonly used rule of thumb measure to describe economic systems (Epstein and Axtell, 1996). The
method used to determine the confidence data only includes the uncertainty in the lidar derived elevation data (root mean square error, or RMSE). This
confidence data shows that the water level depicted in the -6 feet to +6 feet water level change data is not really a hard line, but rather a zone with greater
and lesser chances of being wet or dry. Areas that have a high level of confidence that they will be wet, means that there is an 80 percent or greater
likelihood that these areas will be covered with water. Conversely, there is a 20 percent or less likelihood that the area will be dry. Areas mapped as wet
(inundation) with a high confidence (or low uncertainty) are coded as 2. Areas that have a high level of confidence that they will be dry, means that there is
an 80 percent or greater likelihood that these areas will be dry. Conversely, there is a 20 percent or less likelihood that the area will be wet. Areas mapped
as dry (no inundation) with a high confidence (or low uncertainty) are coded as 0. Areas that have a low level of confidence, means that there is a 21 - 79
percent likelihood of wet or dry conditions. Note that 60 percent of the time, the land-water interface will be within this zone. Areas mapped as dry or wet
with a low confidence (or high uncertainty) are coded as 1.
As with all remotely sensed data, all features should be verified with a site visit. The data are provided as is, without warranty to their performance,
merchantable state, or fitness for any particular purpose. The entire risk associated with the results and performance of these data is assumed by the user.
This data should be used strictly as a planning reference and not for navigation, permitting, or other legal purposes. For a detailed description of the
confidence level and its computation, please see the Mapping Inundation Uncertainty document available at:
http://www.jcronline.org/doi/abs/10.2112/JCOASTRES-D-13-00118.1
The purpose of these data is to show the level of confidence in the water level data based on the uncertainty in the source lidar elevation data.
Acknowledgment of the NOAA Office for Coastal Management (OCM) as the data source would be appreciated in products developed from these data, and
such acknowledgment as is standard for citation and legal practices for data source is expected.

Use Constraints: These data illustrate the scale of potential water level decrease and increase, not the exact location, and do not account for erosion, subsidence,
or future construction. Water level is shown as it would appear based on each lake's long term average water level over the period of record (excludes wind
driven effects) with one foot increments of water level decrease or increase. These data should be used only as a screening-level tool for management
decisions. As with all remotely sensed data, all features should be verified with a site visit. The data set is provided as is, without warranty to its

dataset
Completeness Report
These data are complete. Gaps may exist, but these are due to a lack of available elevation data at the time of data set creation.
Conceptual Consistency
The data were reviewed for consistency and anomalies.
The process to create these data is as follows:
1. NOAA OCM uses the uncertainty of each of the source elevation data sets to create depth rasters and z-score rasters for each water level
(from -6 feet to +6 feet).
2. Each z-score raster is reclassified to areas of low and high confidence. Areas mapped as dry (no inundation) with a high confidence or low uncertainty
are classified as 0. Areas mapped as dry or wet with a low confidence or high uncertainty are classified as 1. Areas mapped as wet (inundation) with a
high confidence or low uncertainty are classified as 2.
