encouraging the use of basic public services. In addition, e- 
government can improve and accelerate the public services and 
can reshape them so that they can be easily got and they can 
meet the needs. Transition to electronic interaction includes 
great changings, which are difficult to manage in institutions 
(Prime Ministery, 2002). 
With December 4, 2003 dated and 2003448 numbered circular, 
one of the goals of the Turkish Republic Government was 
declared as; "To form a government structure which is 
participative, transparent, active and which has the principle of 
having easy workflow for presenting fast public services in high 
quality". General Command of Mapping appropriated to carry 
out its jobs in this respect and has accelerated the studies of 
forming geographic information system and geographical 
database. 
According to 4th article of the law numbered 657, General 
Command of Mapping has been charged with the duty of 
supporting public institutions with geographical products and 
supporting Turkish Armed Forces for defense purposes. Besides 
the other duties it is also responsible for, 
* Taking aerial photographs in different scales, bathing 
and archiving them, 
e Meeting map or photograph needs of ministries, 
public and private institutions according to existing 
law for them. 
The aerial photograph archiving jobs are still carried out by 
traditional methods and need experienced person to accomplish. 
But the developments in informatics technology can effect and 
change the economical, social and cultural structures of 
societies. Accordingly; public and private sectors want to get 
the information they need, fastly and mostly from internet. In 
General Command of Mapping only geodetic and geophysics 
data are being presented by e-mail. But in the future all map 
and map information are aimed to supply. 
General Command of Mapping has finished the technical study 
of presenting its products by using internet. After finishing the 
legal arrangements in Commerce Law with the leadership of 
Ministry of Justice and Ministry of Commerce such as digital 
signature validity or contract prepared in the internet, the 
needed information will be able to be sold through internet. For 
this reason whole archives and catalogues must be prepared in 
digital form. One of these archives is photo laboratory archives 
which have got the films taken since 1930's. 
3. THE STRUCTURE OF EXISTING PHOTO 
LABORATORY ARCHIVES 
Composing of films, after bath, on 1/100.000 or 1/200.000 
scaled maps is prepared by a person in charge in Photo 
Laboratory Branch Office. In this operation which requires 
experience; 
* Aerial photographs in strips are compared with the 
map. 
© Aerial photographs are arranged in flight direction 
according to their overlapping ratio. 
* Enough amounts of photograph center points are put 
in the map and combined. 
Then these film rolls and diapositives are archived_according to 
their dates and film numbers in Archives Section in same 
branch office. The maps that are used in composing are 
archived according to their names, in huge cabinets, in another 
room. 
If it is thought that the whole aerial photographs, which have 
been taken since 1939, are in these archives, greatness and 
historical importance of these archives can be seen easily. The 
most important problem that this archives comes face to face, 
can be seen, if the films which have been spoiled and rotten 
despite ideal room temperature, archives faults and probable 
personnel negligence are appreciated, in this 63-year dynamic 
archives. 
The formal aerial photograph requests from this branch office 
are: 
e By the name of settlements, 
* By coordinates, 
e By map names in different scales, 
e By drawn outlines on a map. 
If the greatness of archives and one person in charge are 
thought, it can be approved that replies to these requests need 
dense labor and experience. It is evaluated that a Photo 
Laboratory Archives Information System which is suited to the 
technological development and meets the needs should be 
prepared. This system is essential to protect the whole aerial 
photographs since the beginning, to improve the archiving 
methods and conditions and to reply correctly and fastly to the 
photograph demands.

The workflow of designing draft Photo Laboratory Archives 
Information System which was designed as sub-system of 
geographical database of General Command of Mapping, suited 
to Turkey National Information System, is presented in

After the system design, pilot project application phase: was 
started. For this reason; 1/100.000 scaled BURSA-G23 map, 
which includes the 1999 earthquake region, was chosen. Then, 
In sequence: 
e The last press of selected map was scanned in 254 
dpi, and was kept in .tiff format. 
e Then it was compressed by using MrSid format 
resulting from 28MB. to 4 MB. (1/100.000 scaled 393
