GIS In Underwater Relief Mapping

GIS In Underwater Relief Mapping
-Exploration of continental Shelf edges. This is
a multibeam map image of a continental shelf edge
Off the coast of South Carolina. By using
underwater GIS we Can get the dimensions of
underwater trenches and this can help Us do many
other things. It may cost a lot to get these
types of Images because many are taken from
ships or subs using sonar, But it can all pay
off in the long run. (www.caris.com/calender/deta

-Other Important benefits Perhaps one of the most
important benefits to Using underwater Gis to
map relief is making it possible To keep track of
underwater tectonics activity Which can lead to
events such as Tsunamis. What GIS can do is show
a before and after Image of underwater ridges or
fault. What this Can do is let scientists know
what has changed . By knowing what has changed
scientists can make Seismic predictions and
potentially save lives. Some downfalls to this
are that underwater events Are hard to predict
and are often not predicted Until it is to late.
Underwater research is Also very hard to fund.
Without funding these Projects can not take
place and lives cannot Be saved.

-A good example of a payoff would be. The ability
to find ships that have met their final resting
places Under water. We can find objects such as
ships by using GIS to Map underwater relief. Any
time there is relief under water (a change In the
sea floor) there has to be an object or
landform. (www.caris.com/calender/details.cfm?img
