Turkish Statistical Regions Classification (2005):
GIS Team – Study (1):
WHY? In the process of harmonization with EU, • to clarify the regional policy frame,• develop regional statistics,• have legislative background
HOW? Basic factors used for identification:• Population,• Regional development plans,• Socio-economic status of provinces,• Statistical indicators,• Geography.
According to current administrative division - 4 levels:• LAU - level 1: 923 region (districts – unofficial),• NUTS level 3: 81 region (provinces – official),• NUTS level 2: 26 region (province groups – official),• NUTS level 1: 12 region (level 2 groups – official).

GIS Team – Study (3):
For the purpose of gathering and processing of the statistics that pertain to artificial and natural areas on the earth (residential areas, roads, agricultural areas, forests, water bodies etc.) on both national and regional scale, via location dependent remote sensed data (satellite images and air photos) in a way to support the traditional data collection methods of the Institute.

Organizational Structure for GIS and RS at TURKSTAT: RS Team
Personnel number: 2
Turkey has approximately 78 million ha total area
Land use data in Turkey are obtained from 2 different sources:• Agricultural censuses• Annual crop production statistics
RS Team – Studies:
Following land use variables have been derived from the census of agriculture:
• unused and undeveloped potentially productive land• permanent meadow• pasture lands• wooded land and forest land• non-arable land
Since 1992, TURKSTAT has carried out two remote Sensing studies for agricultural statistics:
• The first application named as “Cereal Acreages Estimation Project” was carried out between the years 1992-1997. MARS methodology was used for this application.
• The second application was "Determination of Land Cover/Use Map by Using Remote Sensing and Geographical Information System Techniques" on the basis of CORINE methodology between 2001 and 2005.
RS Team – Studies:
IMPLEMENTATION of CLC2000 in TURKEY
CORINE Land Cover 2000 (CLC2000) activities in Turkey have started in the Turkish Statistical Institute (TURKSTAT) in 2001 without any support from European institutions.
• The Eastern part of the country has been finished by TURKSTAT in the summer of 2004. • The Western part of the country has been completed by a subcontractor of TURKSTAT (HAT GIS, Ankara) between August 2004 and January 2005. • The two parts have been integrated to a seamless database by TURKSTAT.
During 2005 an internal agreement have been concluded that CLC2000 in Turkey will be implemented at the National Information Centre, Soil and Water Research Institute of the Ministry of Agriculture (N.I.C.). The parties who have signed this agreement are:
• Ministry of Environment and Forestry (MEF)• Nature Conservation and National Parks General Directorate• Environmental Impact Assessment General Directorate• Authority for Special Protected Areas• Forestry General Directorate (FGD)
• Ministry of Agriculture and Rural Affairs (MARA)• Turkish Statistical Institute (TURKSTAT)

Confidentiality - Granularity
• Not enough granular data, so…however,• Spatial Address Register System is on the way…
• TURKSTAT & Minister of Interior• Turkish NSDI is on the way…
• GIS Directorate is established.• legislative background is ready – yet unofficial• standards are ready - yet not publihsed
