2. STATE INSTITUTE OF STATISTICS
The foundation of modern and scientific statistical services began with the establishment of the “Central Statistical Department” under the Prime Ministry in 1926, three years after the foundation of the Republic. Later, the Central Statistical Department Center was renamed the “Central Directorate of Statistics”. And due to the need for improvements in the statistical system of the country a Law was enacted in June 1962 to set up the State Institute of Statistics under the Offices of the Prime Minister.
SIS is the main official organisation that is responsible for the collection, evaluation and dissemination of statistics for the decision makers, researchers and public in a wide range of issues like economy, demography, agriculture, education, tourism, environment etc.

7. 2002 GENERAL INDUSTRIAL AND ESTABLISHMENT
CENSUS
GIS PILOT STUDY

8. Objectives To provide a geo-referenced address frame based
on establishments
To define enumaration areas
To realise field organisation using GIS
State Institute of Statistics, June 2001
To disseminate census results in geo-referenced form
(paper maps, on web) in addition to tables
Allow SIS users making spatial analysis on addres based
information after census
To develop a model and extend for whole settlements
in Turkey

9. Data to be used in the project
Scale : 1: 1000
Data Source : Digital Maps provided from municipality
Production Year: 1994
Coverage : İstanbul Metropolitan Area – Bahçelievler District
Area: square kilometer
Data layers :
1. District border
2. Quarter borders (11 Quarters)
3. Streets
4. Buildings
5. Parcels
6. Others

10. Main Steps of the Project
Providing Digital Maps
Organizing Data layers
Determining inconsistency (if exists then field work)
Updating maps using high resolution images
Defining enumaration areas according to the criteria that an enumarator can visit at most 15 establishments in a day
Preparing hardcopies showing enumaration areas and address list.
Field work for census
Relating questionnaries to maps
Opening geographic database to other units
Dissemination

11. Enumaration Area Map Used in Pre-test Study

12. CLASSIFICATION OF STATISTICAL REGIONS
OF TURKEY
State Institute of Statistics, June 2001

13. Main Criteria Followed for Defining Statistical Regions
Population
Regional Development Plans
Socio-economic Development Rank of Provinces
Main Statistical Indicators
Geography

14. Turkish Statistical Regions
Turkish Statistical Regions consist of three regional levels corresponding to the existing administrative divisions :
Level 3 : 81 regions (81 Provinces)
Level 2 : 26 regions (group of provinces)
Level 1 : 12 regions (group of level 2 regions)

15. Turkish Statistical Regions - Level 3

16. Turkish Statistical Regions - Level 2

17. Turkish Statistical Regions - Level 1

19. LAND COVER/USE PROJECT
of TURKEY
State Institute of Statistics, 2002

20. The objectives of the project can be given as follows:
To provide the optimal usage of natural resources
in the country
To determine the environmental policies by comparing regional land cover
To construct a spatial data frame for the other
related Surveys
State Institute of Statistics, 002
To update Land Cover Study done by SIS in 1993
To obtain harmonized land use statistics with EU
(The methodology of this project will be same as
CORINE Land Cover Project)

23. The main stages of the Project will be as follows:
State Institute of Statistics, 2002
The main stages of the Project will be as follows:
Covering whole country by high resolution satellite
images ( Landsat 7-ETM images were purchased)
Preparation of 1:100,000 scaled image maps
Geometric correction of satellite images
Image enhancement process for visual image interpretation
(Resolution merge and contrast enhancement processes
were done)

24. Preparation and design of geographical database
Digitisation of resultant land use classes
Integration of land use database with the relevant data from
other Public or Private Organizations in Turkey
State Institute of Statistics, 2002
Determination of land use classes by using photo-
interpretation techniques and by help of ancillary data
(topographic, forestry, hydrological etc. maps )
Plotting of these maps

28. THEMATIC MAPPING Paper Maps Image Maps ( jpg, bmp, cgm etc.)
Internet Mapping (Using ArcIMS)

31. Internet Mapping
The aim is to use GIS technology to support geo-referenced information dissemination with the help of internet mapping tools
Depending on SIS dissemination policy users will have access
to perform queries
to create their own thematic maps
interactively on internet.

32. Internet Mapping
At the beginning web based geo-referenced statistical data dissemination on internet will be based on admininistrative boundaries especially province and district level. For this purpose 1: scaled digital administrative boundary coverage is being used.
