(Submission #256)


Turkey National GIS (TUCBS or TRGIS in English) actions, as National SDI, started in 2004 and have continued with consecutive actions until now. General Directorate of GIS was established in 2011 and accelerated processes of building National GIS. Projects started to define national geo-data standards, to analyse geo-portal development, and to determine institutional and policy requirements.

To develop geo-data standards, use case analysis was utilized to all stakeholders of National GIS, including 15 of ministries, 88 of general directorates, 88 of departments, and 118 of sub-departments. As-is analysis was done with current geo-data specifications. INSPIRE geo-data themes were analyzed because Turkey adopted Europen Union policies. As a result of these; TRGIS geo-data themes were designed for JD-geodesy, TO-topography, OR-ortophoto, AR-land cover, HI-hydrography, UL-transportation, ID-administrative unit, TK-land registry & cadastre, BI-building, and AD-address. TRGIS data specifications were determined with UML application schemas and feature catalogues, based on ISO/TC211 standards and conceptual data components. All application schemas were revised after National GIS stakeholders examined them. Then, GML application schemas of geo-data themes were produced for effective geo-data exchange.

It is supposed that Turkey National GIS data specifications are reference geo-data models that users need to share in their application areas and can be transformed to INSPIRE data sets. These standards are being tested to use in GIS applications corporately. Turkey National GIS legislation was prepared and is about to put into practice. TRGIS portal was built, but it is not available because of some configuration problems.

According to the result of our fieldwork and meetings in Turkey, As understood, public institutions, academicians, and private sectors in GIS industry have deficiencies about SDI vision, understanding and using geo-data specifications suitable to ISO/TC211 standards, INSPIRE and TRGIS geo-data specifications. GIS workers are used to develop applications with traditional approaches that they learned from commercial GIS software. TRGIS and INSPIRE require process-based approach in the long term instead of product-based approach in short term. Uncoordinated bureaucracy and authorization changes constantly hamper the sustainability of TRGIS progress. In this way, solutions, best practices, and experiences will be discussed in TRGIS and INSPIRE implementation.
