Abstract

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 called the Sea Level Rise and Coastal Flooding Impacts Viewer. It depicts potential sea level rise and its associated impacts on the nation's coastal areas. The purpose of the mapping viewer is to provide coastal managers and scientists with a preliminary look at sea level rise (SLR) and coastal flooding impacts. The viewer is a screening-level tool that uses nationally consistent data sets and analyses. Data and maps provided can be used at several scales to help gauge trends and prioritize actions for different scenarios. The Sea Level Rise and Coastal Flooding Impacts Viewer may be accessed at: http://www.coast.noaa.gov/slr This metadata record describes the Honolulu Weather Forecast Office (HFO WFO) digital elevation model (DEM), which is a part of a series of DEMs produced for the National Oceanic and Atmospheric Administration Office for Coastal Management's Sea Level Rise and Coastal Flooding Impacts Viewer described above. The DEMs created for this project were developed using the NOAA National Weather Service's Weather Forecast Office (WFO) boundaries. This DEM includes the best available lidar known to exist at the time of DEM creation that met project specifications for the Honolulu WFO, which includes the following islands in Hawaii: Kauai, Oahu, Molokai, Maui, Lanai, and Hawaii. The DEM is derived from multiple sources. 1. 2006 Hawaii FEMA Lidar - acquired by FEMA along south shores of islands 2. 2007 USACE Pacific Islands Lidar: Hawaiian Islands - acquired by USACE and Hawaii State Civil Defense along north and windward facing shores of islands Hydrographic breaklines were delineated from LiDAR intensity imagery generated from the LiDAR datasets. The final DEM is hydro flattened such that water elevations are less than or equal to -0.5 meters. The DEM is referenced vertically to the Local Mean Sea Level (LMSL) tidal datum with vertical units of meters and horizontally to the North American Datum of 1983 (NAD83). The resolution of the DEM is 3 meters.

Purpose:

The NOAA Office for Coastal Management has developed high-resolution digital elevation models (DEMs) for use in the Center's Sea Level Rise And Coastal Flooding Impacts internet mapping application. These DEMs serve as source datasets used to derive data to visualize the impacts of inundation resulting from sea level rise along the coastal United States and its territories.

Converted from FGDC Content Standards for Digital Geospatial Metadata (version FGDC-STD-001-1998) using 'fgdc_to_inport_xml.pl' script. Contact Tyler Christensen (NOS) for details.

Activity Log 3

CC ID: 717364
Activity Date/Time: 2018-02-08
Description:

Partial upload of Positional Accuracy fields only.

Data Quality

Horizontal Positional Accuracy:

The DEM is derived from the source lidar data. Horizontal accuracy testing is not performed on the DEM. Lidar source data assumed to meet 1 meter horizontal accuracy.

Vertical Positional Accuracy:

The DEM is derived from the source lidar data. Vertical accuracy is not tested on the DEM. Project specifications require all source lidar data used in constructing the DEM to meet FEMA Specifications for Flood Hazard Mapping.

Completeness Report:

A visual qualitative check was performed to ensure data completeness. All available lidar data known at the time of DEM creation that meets project specifications has been used to develop the DEM. Known data gaps may exist where lidar coverage was incomplete.

Conceptual Consistency:

Data covers the tile scheme provided for the project area. Elevation data checked for anomalous elevation values outside expected range.

Lineage

Process Steps

Process Step 1

CC ID: 619055
Description:

The following datasets were used to develop the DEM: 1. 2006 Hawaii FEMA Lidar 2. 2007 USACE Pacific Islands Lidar Hydrographic breaklines delineated from LiDAR intensity imagery generated from the LiDAR datasets.

Process Date/Time: 2012-01-01 00:00:00

Process Step 2

CC ID: 619056
Description:

GeoCue software was used to develop LiDAR intensity imagery from the LiDAR. The raster resolution was 1ft or 0.3 m.

Process Date/Time: 2012-01-01 00:00:00

Process Step 3

CC ID: 619057
Description:

LiDAR intensity images were viewed in 2-D in ArcMap. Hydrographic features were collected as 2D breaklines.

Process Date/Time: 2012-01-01 00:00:00

Process Step 4

CC ID: 619058
Description:

Class 2, ground LiDAR points are exported from the LAS files into an Arc Geodatabase (GDB) in multipoint format. Hydro breaklines are assigned an elevation of -0.5 meters and loaded into an Arc GDB. An ESRI Terrain is generated from these inputs.

Process Date/Time: 2012-01-01 00:00:00

Process Step 5

CC ID: 619059
Description:

The ESRI Terrain is converted to a DEM in Erdas image file format with a cell size of 3 meters. The DEM is reviewed in Global Mapper for incorrect elevations and artifacts that are introduced from source inputs or during the raster creation process. Corrections are applied to the DEMs and reprocessed for review.

Process Date/Time: 2012-01-01 00:00:00

Process Step 6

CC ID: 619060
Description:

All DEMs are loaded into Global Mapper for the last review. During this last review, an analyst checks to ensure full, complete coverage, no issues along DEM boundaries, DEMs seamlessly edge-match, and that there are no remaining processing artifacts in the dataset. Once approved, DEMs are re-projected to the NAD83 geographic coordinate system.

Process Date/Time: 2012-01-01 00:00:00

Process Step 7

CC ID: 619061
Description:

Re-projected DEMs are further assessed for quality and consistency using Global Mapper. Fine-scale features, including bridges over narrow water bodies and small islands, are assessed for accuracy and edited accordingly. Once the DEMs are polished, they are re-projected to the Universal Transverse Mercator coordinate system.
