+ Close inspection of reliability in obtaining a wide
range of geographical analysis and products.
People and organizations examining GIS technology are
initially attracted to it by the many applications and
benefits it offers within their own profession, discipline or
area expertise. There are three GIS capabilities which
have major significance for people and organizations:
e The ability to share common database of geographic
information which often leads to better cooperation
and a vast reduction in redundancy and
inconsistency.
e The ability to bring together unrelated data, using
location as a method for building the relationships
which can lead to interdisciplinary discoveries and
cooperation at many levels.
e The ability to aggregate data into larger geographic
units that are more useful for the large scale
applications which can lead to far better
understanding, cooperation and management of the
operational units within an organization.
The aim of this studies is to show up the importance of
the Geographic Information Systems (GIS) clarifying
basic ad hoc aspects and to set up pilot projects on the
design and implementation of a GIS. The hardware and
software used ITU Civil Engineering Faculty for different
applications are explained (Seker and Altan, 1995).
Some of these applications are;
Environmental Information System,
Information System in Rural Areas,
Information System for ITU Ayazaÿa Campus,
Urban Information System for Public Works of
Municipalities,

3.1. Environmental Information System
The objective of this study is to develop techniques for
establishing an environmental information system and to
explore its utility as an aid for evacuating water quality
management in Porsuk River. Water quality
management constitutes an integral part of research
project on *River Basin Management for the Sakarya
Basin". The project was designed in general, for major
task to develop a better understanding of the water
resources management and to explore the possibilities of
integrated river basin management as the basis for the
comprehensive, multi-purpose management of national
water resources. Porsuk River water quality
management studies is the first application within the
context of the project. This study aims to upgrade the
water quality of the Porsuk River for beneficial uses
planned through the use of on information system abate
environmental impact assessment (Arslan, 1993).
3.2. Information System in Rural Areas
In this study three different applications in the different
parts of Turkey which can be seen in Figure 1. are
performed to investigate the implementation of
information systems in rural areas by using different
kinds of data types in following phases (Seker, 1993,
1995).
- Determine the objectives,
- Creation of the Geographic Database,
- Performing query and analysis,
- Presentation of the results.
