FIGURE 1: The Bi-directional Nature of LIS/G1S
More recently this unidirectional mapping
process has become bidirectional (see
Figure 1) as users of maps and related
products have started playing a more
active role. Although there is still a
demand for the final map product, there is
an increasing interest in the database that
is created in the digital mapping process.
Ultimately the user community is not so
much interested in a map product as it is
in the spatial information that is conveyed
through this medium. This has widened
the scope of LIS/GIS considerably since
we must now incorporate the user
community and its needs. In this way we
are shifting from a supply-driven,
technologically-controlled environment to
one which is demand-driven and oriented
towards problem-solving.
While this technology is playing a role in
defining our technical capabilities, this
would have no value if there were not a
concomitant demand for the resulting
information. Many of the problems that
are being faced by society today—soil
erosion (desertification), water and air
pollution, infrastructure maintenance,
siting of hazardous and solid waste sites,
protection of endangered species, third
world poverty, etc.— can only be solved
or alleviated if we bring together a variety
of information and knowledge from a
number of different sources' and
disciplines.
With increasing concerns about the
environment (evidenced in part by the
emergence of “green” parties) and related
problems like the “greenhouse effect”,
there will be an increasing demand for
approaches that are problem-oriented as
opposed to those that are rigidly divided
on disciplinary grounds. For example, in
an article in Issues in Science and
Technology Schneider (1988) lists the
following elements as being crucial to
addressing the greenhouse effect:
behavioral assumptions (estimating future
pollution levels); carbon cycle response;
global climatic response; regional climatic
response; physical and ecological im
pacts; economic, social and political
inputs; and policy responses. Clearly
these elements of the problem cannot be
addressed from the narrow perspective of
one or two disciplines.
Schneider (1988) argues for an
interdisciplinary (as opposed to a
multidisciplinary) approach that is
oriented around a specific problem area.
To achieve this, he advocates the addition
of “courses and programs that show
graduates and undergraduates how to
approach complex, multidisciplinary
problems, and how to work in teams. At
the graduate level, students should be
encouraged to look beyond a single field
of specialization” (p. 98). This approach
is being following by several of the
LIS/GIS programs at The Ohio State
University (described in the latter part of
this paper).
In the specific context of LIS/GIS, it
seems that what we are attempting to do
is reassemble a complete “picture” of the
human and natural landscape, in the past
the trend has been to cater to disciplinary
specialists by allocating different pieces
of this landscape to such specialists as
hydrologists, soil scientists, geologists,
and others. Now we are realizing that the
only way we can address many of
today’s important problems is to
reconsolidate this situation. It is no
coincidence that many of the leaders in
GIS design and development have come
from a landscape architecture background
