GeoMapApp iconGeoMapApp 3.1.6

An application created for the discovery, exploration, manipulation, visualization and analysis of a large choice of built-in and user-imported data sets.
GeoMapApp is an earth science exploration and visualization application that is continually being expanded as part of the Marine Geoscience Data System (MGDS) at the Lamont-Doherty Earth Observatory of Columbia University. 

This powerful program provides direct access to the Global Multi-Resolution Topography (GMRT) compilation. The database hosts high resolution (~100 m node spacing) bathymetry from multibeam data for ocean areas and ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) and NED (National Elevation Dataset) topography datasets for the global land masses.

What's New in version 3.0.0
  • This release represents a major upgrade to the base topography dataset accessible through GeoMapApp to include the GMRT 2.0, with greatly expanded coverage in the oceans, and the ASTER and NED topography datasets for the global land masses. The ASTER GDEM topography dataset (Japan METI/NASA), provides 30 m resolution for the continents from 83°S to 83°N and replaces the SRTM dataset used in earlier versions of GeoMapApp. For North America, the even higher resolution NED dataset (USGS) is now used, providing topography of the continental U.S. to 10 m resolution.
  • For the oceans, the GMRT v2.0 synthesis includes bathymetric coverage to 100 m resolution from multi-beam bathymetry mapping expeditions and regional gridded compilations from a number of areas and international sources. New data coverage within GMRT v2.0 is focused in the Atlantic and central Pacific with over 100 expeditions added since the prior release, GMRT v1.0. In addition, GMRT v2.0 includes a new 50 m grid resolution layer for the continental shelves and other ocean areas where native resolution of the available sonar data is sufficient. The high resolution bathymetry are merged with the Smith and Sandwell v12.1 global topography compilation, the IBCAO v2.23 for the Arctic, and the BedMap Subglacial Topographic Model of the Antarctic.
