In order to complete rural cadastre, 1/5000 scaled base map production
has been carried out for 480.000 km2 area after 1955 by
photogrammetric method ...
Digital Orthophoto production has been started after 2007 for kadastral
renowation and update works for the purposes of decision-support,
quality control and establishing legal basis

Orthophoto Map Production - Planning
• Considering requests made by the Department of Cadastre,
• Orthophoto map production areas are determined annually
within the context of Joint Map Production Protocol signed
with the General Command of Mapping since 2010.

Existing Situation;
Aerial Photograph+Cadastre; Orthophoto+Cadastre;
Old-dated aerial photographs within the archieve of GDLRC, whose
orthophotos were not produced, are demanded and used by Cadastre
Directorates at renewal and update of cadastral maps
It is quite hard to use these images at cadastral works, which are not in
orthophoto format, having no coordinates & scale and including errors
arising from field slope.
