New! December 7, 2009: GeoMapApp version 2.3
Click here to launch version 2.3 of GeoMapApp using Java WebStart or select from the Download Links menu to the left to install the application.
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. The application provides direct access to the Global Multi-Resolution Topography (GMRT) compilation that hosts high resolution (~100 m node spacing) bathymetry from multibeam data for ocean areas and Shuttle Radar Topography Mission elevations over land.
Requirements
The application runs in the Windows XP, Windows Vista, Mac OS X (10.4, 10.5), Linux and Solaris operating systems using the Java Runtime Environment (requires version 1.5.0_08 or more recent).

Overview
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. One can select and view seismic reflection, gravity, magnetic and topographic profiles from tens of millions of kilometers of ocean surveys dating back to the 1960s. There are dedicated interfaces to explore the results of 40 years of ocean floor drilling, earthquake locations, magnitudes and epicenter depths, and seabed photographs from submersibles, remotely operated vehicles and towed camera sleds. The image in the map window can be saved or sent directly to a printer. Tabular datasets are selectable with lasso tools and can be manipulated in interactive graphs. Gridded datsets can be sun-shaded from selected directions and illumination angles then contoured. Users may import grids and tables from their own file system as well as from Web Mapping and Web Feature Services and take advantage all of the visualization capability of the application.
Version 2.2.0 displays clickable bounding-box overlays in the map window indicating the location of all available datasets when using tear-off menus. The Layer Manager has an additional button to zoom to the region enclosing the data of that layer.
Version 2.2.0 provides links to selected datasets residing at the World Data Center and at the Publishing Network for Geoscientific & Environmental Data (PANGAEA®).
Version 2.2.0 plots symbols on the map using colors represented by comma-separated rgb triplets in any data table column labeled rgb
Version 2.1.0 provides cascading and tear-off menus to facilitate selection from a large assortment of terrestrial and ocean datasets. GeoMapApp now has a Layer Manager that lists the currently selected layers for viewing, re-ordering and individual rendering with variable transparency. Each layer has its own Info Button that displays relevant dataset source and citation information to a browser window as well as a Zoom Button to scale the dataset to the map window.
Version 2.1.0 offers the ability to display images in separate layers either from menu choices or by opening image files in the user's file system, including kmz files. If you are unable to view Geologic Maps or Nautical Charts it is likely that your installed Java Runtime Environment is not sufficiently current.
Version 2.1.0 allows users to run GeoMapApp through a Proxy Server.
Upon startup, there are choices of Mercator, North polar or South polar projections for the map window. Our Virtual Ocean application offers additional visualization on the surface of a rotating 3-D virtual globe with tilting to enhance the vertical exaggeration.
