CoNED Measures Elevation, Helps Model Inundation Scenarios at Hawaiian Cultural Site
In the land of Kamehameha, south of Kona on the big island of Hawaii, a sacred landscape called Puʻuhonua O Hōnaunau faces the uncertainty of the rising seas.
The bones of royal chiefs rest there. Stories of how ancient Hawaiian lawbreakers flocked to this place of refuge still resonate throughout the 180-acre national historic park that surrounds Hōnaunau Bay.
Coastal Storm Modeling System Relies on Elevation Data Provided by CoNED, EROS
With sea levels rising and storms increasingly threatening their shorelines and cliffs, officials in Southern California face some difficult decisions.
CoNED Digital Elevation Model Helps Majuro Prepare for Sea Level Rise
University of Hawaii Geology and Geophysics Professor Chip Fletcher spread his maps on the table as land planners from Majuro—a large coral atoll of 64 islands in the Central Pacific’s Republic of the Marshall Islands—leaned in.

Inundation exposure assessment for Majuro Atoll, Republic of the Marshall Islands using a high-accuracy digital elevation model
Majuro Atoll in the central Pacific has high coastal vulnerability due to low-lying islands, rising sea level, high wave events, eroding shorelines, a dense population center, and limited freshwater resources. Land elevation is the primary geophysical variable that determines exposure to inundation in coastal settings. Accordingly, coastal...

Coastal National Elevation Database
The Coastal National Elevation Database (CoNED) Applications Project develops enhanced topographic (land elevation) and bathymetric (water depth) datasets that serve as valuable resources for coastal hazards research (Danielson and others, 2016; Thatcher and others, 2016). These datasets are used widely for mapping inundation zones from riverine...

Evaluating the potential for near-shore bathymetry on the Majuro Atoll, Republic of the Marshall Islands, using Landsat 8 and WorldView-3 imagery
Satellite-derived near-shore bathymetry (SDB) is becoming an increasingly important method for assessing vulnerability to climate change and natural hazards in low-lying atolls of the northern tropical Pacific Ocean. Satellite imagery has become a cost-effective means for mapping near-shore bathymetry because ships cannot collect soundings safely...
