One Meter Topobathymetric Digital Elevation Model for Majuro Atoll, Republic of the Marshall Islands, 1944 to 2016 Located in the northern tropical Pacific Ocean, Majuro is the capital of the Republic of the Marshall Islands. Majuro Atoll consists of a large, narrow landmass and a set of smaller perimeter islands surrounding a lagoon that is over 100 square miles in size. The waters surrounding the Majuro Atoll land areas are relatively shallow with poorly mapped bathymetry. However, the Pacific Ocean on the exterior of the coral atoll and the lagoon within its interior consist of deep bathymetry with steep slopes. The highest elevation of the Majuro Atoll is estimated at only 3-meters above sea level, which is the island community of Laura located on the western part of the atoll. At the eastern edge of the atoll lies the capital... Categories: Data; Tags: 3D Elevation Program, 3DEP, American Society of Photogrammetry and Remote Sensing, Base Maps, Bathymetric, All tags...

The Republic of the Marshall Islands (RMI) spreads over 29 atolls and has a population of over 50,000 people with homes and communities that may be threatened by these climate change-related events. Policy makers, planners, and others within RMI are faced with decisions about how to prepare for the future and need scientific data and information about the vulnerability of Pacific Islands to potential climate change impacts like sea-level rise.

Detailed knowledge of integrated river system topography, bathymetry, and topobathymetry is essential for fisheries habitat restoration, hydrologic modeling, and other key science applications such as flood mapping and identification of fluvial geomorphic features. An integrated 1-meter topobathymetric digital elevation model (TBDEM) for Hardin, Orange, and Jefferson counties in Southeast Texas has...

Detailed knowledge of integrated river system topography, bathymetry, and topobathymetry, is essential for habitat restoration, hydrologic modeling, and other key science applications such as flood mapping and identification of fluvial geomorphic features. An integrated 1-meter topobathymetric digital elevation model (TBDEM) for the Kootenai River near Bonners Ferry, Idaho, has been developed for this first pilot study. The Kootenai...
