Republic of Turkey the Ministry of Environment and Urbanization General Directorate of Geographic Information Systems True Orthophoto and Geospatial Data Generation Project
The True Orthophoto and Geospatial Data Generation Project has been contracted by the Turkish Natural Disaster Insurance Institution (DASK) and is being carried out by the Ministry of Environment and Urbanization General Directorate of Geographic Information Systems acting as the Technical Coordinator. Social, cultural, industrial, and tourism works on shores and harmonization works of data regarding high-resolution orthophoto generation and road and building digital data generation, with information systems in cities, towns, and major districts covering settlement and development areas of cities on the project area of ~40.000 km2 are being carried out.
It is one of the important projects worldwide, as well as being the first in terms of scope, cost, time, and the technology used. Updated building inventory is established in urban areas, by creating main image base of all departments generating geospatial data and generating true orthophotos at a scale of 1/1000 in high-performance computing environment.
High-resolution orthophoto generation phases start with aerial photo shoots primarily covering the planned flights. Then, the image files are transferred to data storage areas, the stored images are measured and balanced, and the orthophoto generation is carried out by using high-performance computing servers. After the completion of the project, the obtained data shall be put into service of all public institutions and municipalities, and shall be free of charge.
When the project is completed, projects such as planning-designing, urban transformation, urbanization, municipality services, unlicensed construction tracking, decision support, natural disaster planning, and emergency cases shall gain effectiveness and pace. It will also shorten the processes for environmental projects, implementation projects, and planning activities, as well as reducing the costs of municipalities with limited resources for planning and project designing. Besides, damage assessment and coordination activities for organizing the instant response shall be performed in a short time after natural disasters.
