of more than one, availability to easily and effectively report 
creation and stocktaking. ERP targets at all units and functions 
to be integrated in a single computer system for covering the 
needs of special departments. This integrated approach provides 
a high amount of feedback when the software is setup and used 
correctly. 
3.2 Investment Monitoring System 
Investment Monitoring System is a web based software aiming 
at monitoring the tenders made by GDLRC for projects such as 
digital cadastre and renovation. Thus the actuality of the 
information is procured and gains in both time and safety 
aspects are provided. The system affects the expenditure in 
positive way as well as supplying information required for fast 
and reliable reports in means of business intelligence. 
3.3 SGB net 
Strategic management that constitutes the essence of Law No 
5018, together with an understanding of the new public 
financial management, including performance-based budgeting 
and internal control systems, and thanks to SGB.net System, 
which allows to implement these activities, data related to 
public services and work processes is converted to information 
in the digital environment and this information is included in 
the decision making processes to create policy. The system is 
designed to cover all financial processes, applicable to all public 
administrations and structured that can work in an integrated 
way with other systems. 
Since it is a web-based system, it has a substructure that 
everyone can easily access without any extra cost and there is 
no installation cost. The most important feature of the system is 
for the first time a public authority is developed a way not only 
for its own use but also for the use of other public 
administrations. In this way the public administrations can use 
any sub-system or the whole system by adapting their business 
processes the system free of charge. 
Using this program GDLRC prevented the duplication of 
investments; savings were achieved both in terms of time and in 
financial terms. Planning, implementation, monitoring and 
control components form the basis of the system, thus a link is 
established between plan and implementation, application and 
monitoring, monitoring and control. In this context, each 
component is supported by various developed modules. These 
modules are: The Library Module, Receivable Tracking 
Module, Chattel Registration Module, Expenditure 
Management Module, Budget Preparation Module, Budget 
Processes Module, Performance Budget Module, 
Internal/Preliminary Linancial Control Module, Document 
Management Module, Identity Sharing Module, and User 
Management Module. 
3.4 On Line Analytic Processing (OLAP) Cubes 
Work done by staff employed by the company and work periods 
are defined. The web-based software is developed for tracking 
tasks and timelines. Each employee records the work done and 
duration of the work performed to the system. 
Via OLAP reports, the institution top manager can view how 
any staff spends the day, how the pace of the work is and the 
behavior characteristics and so on as a report based on careers, 
units and time intervals. In this way it could be more efficient in 
terms of management. Lor instance, performance management, 
resource management, work flow management, etc. is easier. 
With these reports, people could be managed more effectively, 
individuals might be utilized more effectively and in terms of 
work the most appropriate people can be determined. 
OLAP means intervention to the costs in the large means in 
terms of immediate intervention of human resources for the 
disruptions to the works in progress or in planning, or projects. 
4. COST ANALYSIS 
It is difficult to separate costs in public sector. The biggest 
reason for that is the lack of profit for the public sector. 
However, changes in the production costs can be observed by 
comparing technological developments and changes with its 
resulting production. It is not hard to predict that projects 
mentioned above provide large gains during years. 
Comparison of the spatial data production will be done with 
respect to years in order to observe improvements in production 
cost and to have an idea.

Table 1 : The quantity of aerial photography acquisition in the 
last decade 
It can be seen from the table above that there is a great increase 
in acquisition of aerial photos after 2009. Climate and weather 
conditions, of course, cannot make such a big impact. The 
biggest reason for the increase is using digital photogrammetric 
systems instead of analog devices for the production. 
Processing steps such as rolling, bath-printing etc. in the 
production of maps done by analog devices do not exist in 
digital systems. Besides, error rate is less at analog system 
compared to digital system, because the calculations in digital 
system are adjusted automatically. This means cost and time 
savings which can be easily seen.
