Summary
Establishment of spatial information infrastructure was made into a necessity by the “Information
Society Strategy Action Plan" prepared by the State Planning Organization, and the Ministry of
Environment and Forestry was defined to be the relevant institution on this subject. In Turkey, those
institutions that are defined to be the relevant and responsible institutions concerning the
establishment of spatial information infrastructure, conduct their studies considering the policies and
directives set out by the European Parliament and Council. Ministry of Environment and Forestry runs
the Project “Establishment of Spatial Environmental Plan Portal" in Geographical Information System
environment based on INSPIRE and ISO TC-211 standards.
Ministry of Environment and Forestry set out a requirement to transform the dispersed plan data that
were produced by the Directorate General of Environmental Impact Assessment and Planning without
a certain standard in the scope of “1/100.000 scaled Territorial Plans” into a form that can be
compared, assessed, interrogated, developed and updated and that has a standard database.
Through this Project, Ministry of Environment and Forestry aims at collecting the data of Territorial
Plans on a single geographical database environment that is redesigned based on INSPIRE and ISO
TC-211 standards; conducting the monitoring and inspection on database environment; and
presenting to the relevant units via web. Thereby, it is provided for research, planning and decisionmaking units to reach institutional information quickly, to create necessary reporting and statistical
data by making correct interrogation on current data, to present the created results on a multi-user
environment on different medias at the institution.
With the database design created in the scope of the Project, it is aimed to manage and update the
geographical data used by the units, and to prevent data duplications. It is planned to integrate the
territorial plans that is the sub-component of the project “Ministry of Environment and Forestry
Development of Geographical Data Infrastructure" on a single database and in the framework of
international standards.
The Project covers all the data of 1/100.000 scaled Territorial Plan of the 11 Planning Regions (34
provinces) that was made by the Directorate General of Environmental Impact Assessment and
Planning and of the 15 Provinces made by the relevant Governorship. The data of this plan constitutes
the data resources of the project.
The Project consists of three stages; namely the “Analysis and Design”, “Data Integration” and “Web
Application and System Operation”. In the scope of analysis, the requirements are determined by
examining all vectorial and graphical data and necessary studies are conducted to establish the
design of new database. During data analysis, data features like data ownership, data quality, current
situation are examined in detail in terms of metadata information and a database design is created in
accordance with the metadata standard of INSPIRE and in a format to enter the metadata of each
layer.
After analyses are made and requirements are defined, it is designed how to organize these data in
the database; information like data type, data definition, possible values of data, attribute information
on data and metadata information are defined and a database design was established in compliance
with data definition guides of INSPIRE. except for INSPIRE and ISO TC-211, data standards like OGC
(OGC Working Groups), UML, XML were considered in the database design which was prepared on
the basis of the analysis. The database design was transferred to UML diagrams, as in the data
models published in the annex of INSPIRE Directive and guidelines were prepared for each layer, as
in the INSPIRE data sets.
The database was designed to be in accordance with topology structure of Geographical Information
System and to work on multi-user environments. In the phase of creating symbologies related with the
database, standard projections are used that are defined in the Annex of By-law on Territorial Plans of
the Ministry of Environment and Forestry. A style file was created to be used by desktop geographical
information system softwares and this file was made into a guideline. At the end of this phase, a
general standards document was created to be the guide for establishment of Territorial Plan
database that is to be formed later.
In the scope of data integration, which is the next phase, graphical and verbal data of the present
plans were transferred to the database whose design was completed. Transferring data to the
database was made in compliance with the GIS logic, and verbal and graphical data loss did not occur
at this phase. Besides, contrasting data samples and unnecessary data duplication were prevented
through this, and the most effective use of time, manpower and present resources was demonstrated.
Lastly, the database was transferred to the spatial database which can operate directly and problemfree on the relational database management system software, that is present at the Ministry, without
needing any additional applications, and which can provide data transfer from one to another
database, independent update of databases and synchronization of changes when requested.
The web-based application software that was created in the last phase of the project, is being
developed on the Advanced Geographical Data Server (ArcGIS Server Advanced Enterprise) that
operates on the relational database management system at the IT Department of the Ministry of
Environment and Forestry. With the application software, graphical data like administrative borders,
land uses, protected areas, transportation and infrastructure and table data and reports can be
queried, and various GIS analyses like buffer zone analysis will be able to be conducted. Besides,
metadata query of data can be made through the application.
At the end of this project, it was provided to make digital data of 1/100.000 scaled territorial plans to be
redesigned, integrated and manageable.
