SI/GI Data
13
Spatial Data Providers

• General Directorate of Land Registry and Cadastre
• General Command of Mapping
• Provincial Bank
• Local Governments/Municipalities
• Other Governmental Institutions
• Private Companies

14
Spatial Data Owners

• General Directorate of Land Registry and Cadastre
• General Commander of Mapping
• Provincial Bank
• Local Governments
• Other Governmental Institutions

15
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.

• Central Government
• Local Government
• Municipality
• Utilities
• Defence and Military
• Public Security
• Disaster Management
• Education/Research

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.

18
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  quickly getting out of date.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.

19
Best Practices

• Land Registry and Cadastre Information System
  TAKBIS
• Marmara Earthquake Region Land Information System
  MERLIS
• Istanbul Great Municipality Urban Information
  System
• Bursa Great Municipality Urban Information System
• e-government
• Seddulbahir and Kumkale Fortresses Documentation
