SI/GI Data
Spatial Data Providers
• General Directorate of Land Registry
and Cadastre
• General Command of Mapping
• Provincial Bank
• Local Governments/Municipalities
• Other Governmental Institutions
• Private Companies
Spatial Data Owners
• General Directorate of Land Registry
and Cadastre
• General Commander of Mapping
• Provincial Bank
• Local Governments
• Other Governmental Institutions
Legislation
• All SI/GI data are protected by Turkish Republic
Official Law. However the law is not well detailed,
therefore comments might be necessary to clarify
the usage.
• New regulation was released in July 2005 for precise
high resolution/large scale spatial data production.
• Not yet special law for National SDI. It is under
preparation. It is in government action plan (2003) as
activity 47, activity 36 and activity 75
• Other governmental documents - Some of the
institutions/organisations prepare their own official
rules regarding their needs.

Strengths
•
Spatial data have been collected using modern technology since
beginning of 1900s in Turkey
•
Governmental institutions are responsible to archive the spatial
data
•
Spatial data are protected by laws for public benefits
•
Spatial data are exchanged between the governmental institutions
• Latest data collection technology is closely followed and
technical regulations are modified regarding the scientific and
technological developments. The new regulation was released in
July 2005. Regarding this regulation spatial data collection for
large scale applications are standardized for all governmental
institutions, therefore for private institutions.
• New 4D geodetic network has been established based on
artificial satellite technology and regularly updated.
Weaknesses
•
Very old spatial data still exists, needs to be modernized.
•
Still no single standards in all level, governmental institutions apply
institutional standards while collecting spatial information.
•
Cadastral works has not been completed for all over the country.
Most existence ones need renewing.
•
Tectonic movements are very effective all over the country.
Therefore spatial information is quickly getting out of date.
•
Existing cadastral laws do not fit the needs of modern digital
information systems
•
Using small scale spatial data needs military permission.
Best Practices
• Land Registry and Cadastre Information System – TAKBIS
• Marmara Earthquake Region Land Information System – MERLIS
• İstanbul Great Municipality Urban Information System
• Bursa Great Municipality Urban Information System
• e-government
• Seddulbahir and Kumkale Fortresses Documentation Project
Land Registry and Cadastre Information System
- TAKBİS -
