GeoMapApp – earth science exploration and visualization application

GeoMapApp is an open source, earth science exploration, global topography database, 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.

GeoMapApp relies on the internet to access a rich content of information for physical oceanography, paleoclimates, geochemistry, geology, seabed sediment and rock compositions, ocean crust age, spreading rates, bathymetry, and sediment thickness.

GeoMapApp is widely used by geoscience educators and researchers as a tool for discovering and integrating multidisciplinary earth science research data, for proposal preparation and meeting presentations and talks, for the generation of figures for publications, and for a broad range of education practices at the graduate, undergraduate and high-school level.

Features include:

  • Direct access to the Global Multi-Resolution Topography (GMRT) compilation:
    • 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.
