multimedia companies are now announcing
products which can be run over the internet,
allowing users to simply click on the file of inter-
est and run the production in real time. These
capabilities help solve the second problem men-
tioned, the distribution of information for easy
access by analysts and managers,
Multimedia has intrigued people for the
past several years but has also presented signifi-
cant technical challenges in computation, mem-
ory, storage, communications, and user interface.
For example, 8 bit audio files, a standard CD
ROM sound resolution, require 22 kilobytes per
second or 1.3 megabytes per minute. Video files
can vary widely depending on the compression
algorithm and image complexity but generally
range from 250 kilobytes to 3.5 megabytes per
second or 15 to 210 megabytes per minute.
As Figures 2 through 5 show, the appro-
priate hardware infrastructure for multimedia is
now becoming affordable and, in some cases,
standard, launching a new approach to the distri-
bution of complex information. Greater amounts
of memory per dollar will assist in the real time
rendering of 3-dimensional data or lengthy times
series of images. One multimedia window could
provide the user with the option to view 3-
dimensional, temporal data in a variety of ways
as defined interactively by the user rather than as
a prerendered set of images. Higher resolution
displays will show a full satellite image on a sin-
gle screen - all in true color. It will also support
multiple multimedia windows, each of which
will be able to manage a high resolution view of
the information involved, e.g. video in one win-
dow and a 3-dimensional rendering in another.
Improvements in storage and processor speed
will assist in managing the multitude of images
involved in a full scale multimedia production.
All of these technologies support the representa-
tion of the data or information in a way which
makes it more useful to the end user.
The impact of the dramatic increase in the
communications bandwidth will be the ease with
which multimedia files can be distributed to any
interested party. Even large images or animations
covering a long time period will not create the
transmission and performance barrier they do
today. For instance, with a 100X increase in com-
munications bandwidth, the 50 megabyte file
which required 40 seconds to transmit over a T3
line could require only .4 seconds in the year
2004.
The increase in communications band-
width will also make it possible to interact with
multimedia products over the internet or other
high speed lines. Today such files can be viewed
but in several years a user will be able to interac-
tively select images to be viewed, choose the rep-
resentation, and make comments on his/her
perception of the issue.
Given the bandwidth, the reduced cost of
transmission, and the trend towards distribution of
executables (versus requiring special software),
multimedia over the network will be far easier
than paper publication. Environmental impact
statements have been mentioned as an example but
clearly the possibilities extend far beyond that,
into both simple and complex problem representa-
tion.
Together with the high demand for more
informative, and fun, approaches to complex data,
the trend in multimedia is likely to be towards
lower costs and rapid growth. If multimedia can
also solve the two problems addressed in this
paper, improved representation of information and
easy accessibility to that representation, growth in
the natural resources arena is certain to be substan-
tial.
