GeoMapApp is a data exploration and visualization tool that is continually being expanded as part of the Marine Geoscience Data System.  GeoMapApp is an integrated mapping application developed at Lamont-Doherty Earth Observatory. It is a Java™ application that may be freely downloaded from www.geomapapp.org, and will run on all platforms with a Java Runtime Environment (standard or available for Windows, MacOSX, Solaris and Linux). Learn more about GeoMapApp by reading about GeoMapApp, the Help pages, and the Development History.

GeoMapApp is your window into a global, multi-resolution digital elevation model. The GMRT includes high resolution (~100 m node spacing) topography from multibeam data for ocean areas and SRTM - Shuttle Radar Topography Mission (http://www2.jpl.nasa.gov/srtm/) - over land.

Updating your Mac: We will soon be releasing GeoMapAppVG which includes WorldWind 3-D visualization. WARNING: To use this on a Mac, when you upgrade to Leopard 10.5.2 do not install the new graphics update (February 2008 - http://www.apple.com/support/downloads/leopardgraphicsupdate10.html) because it will break your Java!  We are currently trying to find out if this particular update can be uninstalled and if steps are being taken to correct the problem.
