3D Visualization of Oceanographic Forecasts
Below are links to kmz files which include all images.
They take longer to start in Google Earth but will need to be downloaded only once.
In movie mode, please allow enough time for GE to register all the images.
The Stevens Institute of Technology has a rich data catalog of meteorological and oceanographic
observations and predictions from the NYHOPS system that is actively utilized by diverse groups
including Office of Emergency Management, Emergency Management Service personnel, the
navigation community, the
fishing and recreational maritime community, and oceanography researchers within and
outside the east coast of the US. The data are now accessible
in Google Earth, greatly expanding the potential user audience while providing
additional options to users of the traditional
Google Earth features (such as panning, zooming, and fly-throughs) allow the user to
view georeferenced data, such as the NYHOPS forecasts, interactively in a
realistic, virtual 3D world. Further, oceanographic phenomena (including freshwater events)
are easily explored through 24-hour animations of forecasted fields such as currents, temperature,
Future developments include automatic generation and dissemination of navigation route maps. These
maps will be used to aid ships in safe passage through the harbor approaches and interior waters.
(An example transit of a ship moving north from the anchorage into NY Harbor and lower Manhattan may be seen here.
The route maps will also be used by devices such as autonomous unmanned underwater vehicles.
Benefits of 3D Visualization Tools to Users
NYHOPS predicts marine weather conditions (water elevation, 3D currents, and surface waves)
that are of interest to the maritime community. The system also forecasts coastal and inland flooding.
Upwelling and downwelling events that affect nutrient replenishment are also predicted.
Other NYHOPS variables of specific local interest include
salinity for marshland health, chromophoric dissolved organic carbon
for underwater visibility, speed of sound for underwater acoustics, etc.
With our experimental Google Earth-based product, under development, a user can easily determine the precise geographic
location (latitude/longitude) of an event or condition in which he or she is interested,
and then follow that event as it unfolds across 24 hours. Since multiple parameters can
be selected at once, direction of currents can be overlaid on top of sea surface salinity
maps, for example, to track the spreading of a coastal plume.
