N2 - What scale is the GIS basic scale? The answer of this question is very important. Since when GIS applications are investigated in the world today, it is seen that GIS developers' concepts mainly intersect on small scale applications. However digitals maps scale is starting from 1 over 1 which represents real dimension. Therefore the resolution and positioning quality of data defines the scale of applications. If so, GIS scale starting from 1 over 1. In that case GIS concept might be expressed as a pyramid and from bottom to top, and it might be ordered as Land Information System, Urban Information System and finally Special Purpose GISs. Certainly there are two main indispensable information structures at the very bottom of this pyramid. They are a precise, reliable and robust geodetic infrastructure and basic maps respectively. Remote Sensing and Photogrammetry are mainly used as geo-data collection technologies. Therefore they take place to produce basic maps and related data collections in that definition. So both technologies need to stand on geodetic infrastructure. Hence this paper has been prepared for transferring information about geodetic infrastructure of Turkey to the people who would like to carry out GIS, Remote Sensing and Photogrammetric applications in Turkey. From that point further in this paper reader will obtain detail information about existing coordinate systems and their responsible institutions in Turkey. More over, way of working with these coordinate systems will be expressed. Thereafter sufficiency of geodetic infrastructure of Turkey will be discussed for GIS applications and data collection techniques, like Remote Sensing, Photogrammetry and GPS. Finally close future strategies on national geodetic infrastructure that are going to be applied in Turkey will be pointed out and interpreted.
