systems based on some tests and trials that have been
done in various military bodies. For the technological
evaluations of GIS in CCIS systems, there have been
many tests. The tests that have been done around in
various military bodies concentrated on mainly;
a) Comparison of WEB and Client/Server
architectures,
b) Comparison of RDBMS and file system
storage of spatial data.
Under those basic circumstances the tests are based on
the criteria such as data access, query, display,
symbolization, zoom in/out, panning and etc. On those
tests, the type of the data used is 2D/3D Raster and
Vector data, satellite imagery and gazetteer data.
The results of those tests can be summarized as;
In terms of comparison of RDBMS and file system
storage of spatial data:
e In the database storage; security, update and raster
data access are ‘Easy’ but in the file system, they
are ‘Hard’.
e Open format standard is available for database
storage but not for the file system.
e Response speed is ‘fast’ for database storage but
‘slow’ for the file system.
e Indexing is available for database storage but
“limited” for the file system.
In terms of comparison of WEB and Client/Server
architectures:
e There is no need for; high capacity RDBMS server,
high capacity WEB GIS server, high capacity
network b/w client and server, high capacity
network b/w RDBMS server and Web server for the
WEB Architecture, but all those are necessary for
Client/Server architecture.
* Technological future expectations are exist for
WEB Architecture, but not for the Client/Server
architecture.
* Response speed is "Fast in WEB Architecture but
‘Slow’ in the Client/Server architecture.
e Network load is ‘Low’ in WEB Architecture but
‘High’ in the Client/Server architecture.
* Management and SW upgrade is Easy’ in WEB
Architecture but Hard in the Client/Server
architecture.
* Cost of the WEB Architecture is " Low after 50
users’ but High' in the Client/Server architecture.
* Unnecessary Functions are "Limited in WEB
Architecture but ‘Many’ in the Client/Server
architecture.
In line with the assessments above; the most effective
architecture is *WEB based GIS architecture with
RDBMS based spatial data storage"
3.2 The Implementation of the Test Results at the
COP (Common Operational Picture) Concept
The COP was designed for two purposes. One of them is
to be a situational awareness tool for the majority of the
users for assigned Areas of Responsibility (AOR) and
Areas of Interest (AOI). Especially for the decision
mechanism, functional enhancements such as logistics,
intelligence ete. provides multi dimensional view of the
645
(ITR
theatre. Second purpose is, to be a decision support
utility via monitoring, recognized Maritime, Air and
Ground pictures on a single screen. Thus, COP provides
basically data sharing and co-operative working
opportunity in other words information flow among
various information systems and user groups via
network. Interoperability is secured by common GIS
environment and integral Functional Information such as
operation, intelligence, logistics etc.
COP has the ability to show the;
e Maritime Recognised Picture
e Ground Recognised Picture
Air Recognised Picture
Intel Recognised Picture
Logistic Recognised Picture
Meteorological Picture

COP is a helpful tool for the decision making. For this
reason, according to the information requirements of the
decision mechanisms, only the concerning aspects of the
CCIS and theatre are projected on the screen. In fact
“Common” Operational Picture reflects 3 dimension of
the real theatre via recognized Maritime, Air and Land
pictures, but concerning aspect is related to the command
level of decision mechanism.
The data for COP comes from;
e ARP, MRP and LRP track/force element data.
e Information on forces (enemy, friendly & neutral
ORBAT).
e Planning data.
e Historical data.
e Intelligence and logistics data.
e Geographic and meteorological data.
