DIGITAL MAP APPS
Dynamic Digital Maps are computer programs that can distribute geologic maps, imagery/movies, and tabular/text based data like chemical analyses and field descriptions in a cross-platform, web-enabled format that is intuitive, easily searchable,and requires no proprietary software to operate. The program acts as an organizational framework and index for presenting maps, imagery, videos and other externally hosted data. A DDM can be downloaded to the user's desktop in any format (e.g. Linux, Windows and Macintosh). When decompressed, the DDM accesses its associated data directly from the host site with no browser needed. Alternatively, the entire package can be distributed and used from CD, DVD, or flash-memory storage.
GeoMapApp and Virtual Ocean are a cross-platform geospatial data visualization system maintained by the Integrated Earth Data Applications (IEDA) geo-data facility at the Lamont-Doherty Earth Observatory. The GeoMapApp DEM is the LDEO Global Multi-Resolution Topography (GMRT) compilation; Virtual Ocean places the GeoMapApp DEM and data on the NASA WorldWind virtual globe. A range of "packaged" global datasets are available for use in GeoMapApp, and one can import geophysics and geochemistry research datasets directly from the IEDA digital collections, as well as selected datasets from other geoscience data portals. One can also map your own geospatially constrained data onto GeoMapApp from a simple Excel file, and generate topographic/bathymetric profiles and other graphical representations of mapped data for further study. GeoMapApp can import shape files and kml/kmz files, and can generate these file formats for export to Google Earth or ArcGIS.
