Orthophoto information system in Turkey in the view of spatial data infrastructure

الملخص EN

Spatial technologies are evolving quickly, particularly with regard to land related data.

The design of land information system needs to be efficiently comprehensive to take these into account and manage them through a Spatial Data Infrastructure (SDI).

The most effective management with the technological trends is likely to lie in spatial enablement ofthe various sets of information.

SDIs aim to facilitate and coordinate the sharing of spatial data between stakeholders, based on a dynamic and multi-hierarchical concept that encompasses the policies, organizational remits, data, technologies, standards, delivery mechanisms and financial and human resources necessary to ensure that those working at appropriate (global, regional, national, local) scale.

Satellite images and/or aerial photographs, which are one of the indispensable layers of spatial information systems, are quite important in the context of National Spatial Data Infrastructure (NSDI).

This study overviews the photogrammetry, orthophoto production studies and Orthophoto Information System (OIS) in Turkey within the scope of SDI.
