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.

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.

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...

Introduction: Special issue on advances in topobathymetric mapping, models, and applications

Detailed knowledge of near-shore topography and bathymetry is required for many geospatial data applications in the coastal environment. New data sources and processing methods are facilitating development of seamless, regional-scale topobathymetric digital elevation models. These elevation models integrate disparate multi-sensor, multi-temporal...

Topobathymetric elevation model development using a new methodology: Coastal National Elevation Database

During the coming decades, coastlines will respond to widely predicted sea-level rise, storm surge, and coastalinundation flooding from disastrous events. Because physical processes in coastal environments are controlled by the geomorphology of over-the-land topography and underwater bathymetry, many applications of geospatial data in coastal...
